Emotions And Conscience: Intertwined Complexity

Emotions and consciousness are two complex phenomena that are frequently experienced together, yet they remain enigmatic. Emotions are multifaceted, involving changes in subjective experience, cognition, action, expression, and physiology. Consciousness, on the other hand, is associated with information processing functions and specific neural substrates.

The relationship between emotions and consciousness is a topic of ongoing research and debate. Some theories propose that emotions are fundamentally linked to consciousness, while others suggest that emotions can occur independently of conscious awareness. The James-Lange theory, for example, considers emotional feelings as perceptions of physiological body changes. However, contemporary theories, such as the constructionist view, propose that emotions are constructed through a combination of bottom-up affective and top-down cognitive processes.

The study of conscious emotions in animals is particularly challenging due to the lack of verbal reports, which are typically used to assess conscious experiences in humans. However, advancements in neuroscience and comparative cognition offer potential markers and methods for investigating conscious emotions in animals. These include studying brain structures and functions, individual variation in emotional awareness, and decision-making processes.

Overall, the intersection of consciousness and emotion is a fascinating area of research that holds the potential to enhance our understanding of the human mind and the minds of other species.

The role of the body in emotional feeling

The body plays a crucial role in emotional feeling. This is evident in the James-Lange theory, which posits that emotional feelings are perceptions of physiological body changes. This theory has been modified and resurfaced in modern neuroscientific and philosophical concepts of embodiment. The body's vegetative and sensorimotor functions are integral to constituting emotional feelings, and as such, the body cannot be considered in an objective way. Instead, it is experienced subjectively.

The body and the environment

The body is in direct contact with the environment through its sensorimotor functions, which are emphasised in recent body-based concepts of emotional feelings. The body represents the environment through these sensorimotor functions, and it is these bodily representations that are considered crucial in constituting emotional feelings.

However, it is also possible to imagine that the environment has a direct and constitutive role in emotional feeling. In this case, emotional feelings would be constituted directly by the person's relationship with the social environment, rather than indirectly via bodily representations.

Neural bases of interoceptive and exteroceptive awareness

Recent imaging studies have investigated neural activity during interoceptive stimulus processing, such as evocation of blood pressure changes, heart rate changes, and skin conductance. These studies observed neural activity changes in regions like the right insula, anterior cingulate cortex, and amygdala. These regions are assumed to be involved in representing the autonomic and visceral state of the body and thus interoceptive processing.

Interoceptive and exteroceptive awareness

The question arises as to whether the above-mentioned data supports an embodied concept of emotional feeling or a relational concept. The paradigms employed did not investigate interoceptive stimuli in isolation from exteroceptive stimuli but rather in relation to them. Neural activity changes assumed to be specific for interoceptive awareness thus reflect a dynamic balance between intero- and exteroceptive processing rather than isolated interoceptive stimulus processing.

The role of the environment in constituting emotional feelings

The relational concept of emotional feeling proposes that the environment has a direct and constitutive role in emotional feelings. This implies that the environment itself is constitutive of emotional feeling rather than the bodily representation of the environment.

Empirical implications: connectivity and coding

Anatomical connectivity and intero-exteroceptive convergence are important considerations in understanding the neural bases of interoceptive and exteroceptive awareness. The medial orbitofrontal cortex and ventromedial prefrontal cortex have been implicated in interoceptive processing and are part of the anterior cortical midline structures (aCMS). These regions have extensive connections with both intero- and exteroceptive inputs, making them polymodal convergence zones.

Translational versus relational coding

The relational concept of emotional feeling proposes that interoceptive and exteroceptive stimuli are coded in relation to each other, rather than being separately represented and then translated. This coding allows for the assignment of subjective and affective features to the otherwise objective and non-affective stimulus.

Objective-subjective transformation

The relational approach to emotional feeling suggests that the brain's resting state activity is crucial in generating affect. Any stimulus, internal, external, or neural, interacts with the brain's resting state activity, individualizing and privatizing the stimulus and transforming it from an objective to a subjective one.

Non-affective-affective transformation

The question arises as to how non-affective stimuli can be assigned affect. One possible mechanism is through the continuous presence of interoceptive input and subsequent rest-intero interaction, which may lead to what is known as Core Affect. This continuous neural processing of the body's interoceptive stimuli against the brain's neural stimuli may transform the originally non-affective interoceptive stimulus into an affective one.

Dissociation between subjectivity and affectivity

The relational approach to emotional feeling proposes that affectivity and subjectivity are co-constituted. However, in certain cases, such as schizophrenia and depression, this co-constitution may become dysbalanced. In schizophrenia, for example, rest-intero and rest-extero interactions may be reduced, leading to an abnormal loss of subjectivity. In depression, rest-intero interaction may predominate over intero-extero interaction, resulting in a state of "non-feeling".

The role of the environment in constituting emotional feeling

The relational concept of emotional feeling

The relational concept of emotional feeling proposes that the environment has a direct and constitutive role in emotional feelings. This means that the environment itself is constitutive of emotional feeling rather than the bodily representation of the environment. In other words, emotional feelings are directly shaped by the relationship between a person and their social environment, rather than being mediated by the body's sensorimotor and vegetative functions.

Neural and cognitive correlates of emotional consciousness

To understand the role of the environment in constituting emotional feeling, it is essential to consider the neural and cognitive correlates of emotional consciousness. Here are some key findings and theories:

• Higher-order theories of consciousness: These theories propose that a first-order representation becomes conscious only when it is the object of a higher-order representation. The higher-order representation can be either a metacognitive process or a self-representation. While some proponents argue that higher-order theories imply that many animals lack conscious experiences, others suggest that simpler forms of higher-order representation may be sufficient for animal consciousness.
• Global Workspace Theory: This theory posits that consciousness arises from the broadcasting of selected information across a network of modular processors in the brain. According to this theory, conscious emotion would involve the broadcasting of affective information for the flexible coordination of behaviour.
• Integrated Information Theory: This theory proposes that consciousness arises from the integration of information in a system, with higher levels of integration corresponding to higher levels of consciousness. According to this theory, conscious emotion would involve the integration of affective information with other types of information in the brain.
• The role of the brainstem: Some theories propose that the upper brainstem, including structures such as the periaqueductal gray, may play a crucial role in generating conscious experiences, including emotional ones. This idea challenges the traditional focus on cortical regions in consciousness research.
• The role of the cortex: The cortex, particularly the prefrontal cortex, has been implicated in various aspects of emotional processing and consciousness. Damage to certain cortical regions, such as the orbitofrontal cortex and the anterior cingulate cortex, has been found to impair conscious emotional experiences.
• Individual variation in emotional awareness: Studies have found that individual differences in emotional awareness are associated with variations in brain activity, particularly in the dorsal anterior cingulate cortex and the insula. These findings suggest that conscious emotional experiences may be influenced by individual differences in interoceptive awareness and the ability to detect and classify emotional feelings.
• The role of decision-making and choice: Affective states in humans have been found to influence decision-making and choice behaviours. The question of whether these processes require conscious emotional experiences or can occur unconsciously is still under investigation.

The relationship between intero- and exteroceptive stimuli in emotional feeling

The relationship between intero- and exteroceptive stimuli and their impact on emotional feeling is a complex and multifaceted topic. In this section, we will explore the latest research and theories on the subject, focusing on the role of the brain, body, and environment in shaping our emotional experiences.

The Role of the Brain

The brain plays a crucial role in processing interoceptive and exteroceptive stimuli, which are essential for our emotional experiences. Interoceptive stimuli refer to input from our own body, such as physiological changes, while exteroceptive stimuli refer to input from the external environment. The brain integrates these stimuli to form our emotional responses.

The Neural Correlates of Consciousness

Several theories have been proposed to explain the neural correlates of consciousness, including higher-order theories, global workspace theory, integrated information theory, and the role of the brainstem. While there is no consensus on which theory is correct, these theories provide insights into the potential neural substrates of conscious emotion.

The Embodied Approach to Emotional Feeling

The embodied approach emphasizes the crucial role of the body and its vegetative and sensorimotor functions in constituting emotional feelings. This perspective suggests that the body cannot be considered merely as an objective entity but rather as a subjective and experienced entity.

The Relational Concept of Emotional Feeling

The relational concept of emotional feeling proposes that the environment has a direct and constitutive role in shaping our emotional experiences. This means that the environment itself is integral to emotional feeling rather than simply modulating it through the body and its sensorimotor functions.

Interoceptive and Exteroceptive Awareness

Studies have shown that interoceptive awareness is closely related to emotional arousal and subjective experience. However, the question of emotional valence, which indicates whether a feeling is positive or negative, remains unresolved. Regions associated with emotional valence include the medial orbitofrontal cortex, subgenual and pregenual anterior cingulate cortex, and the ventromedial prefrontal cortex.

The Intrinsic Linkage Between Intero- and Exteroceptive Stimuli

The brain's intrinsic activity, such as resting-state activity, also plays a crucial role in emotional processing. This activity interacts with both intero- and exteroceptive stimuli, influencing how we perceive and respond to our environment.

The Subjective Nature of Emotions

The subjective nature of emotions is a key aspect of our emotional experiences. By interacting with the brain's intrinsic activity, interoceptive and exteroceptive stimuli can become subjective and privately experienced. This transformation from objective to subjective is facilitated by the brain's resting-state activity, which individualizes and privatizes the stimuli.

In conclusion, the relationship between intero- and exteroceptive stimuli is complex and multifaceted. The brain, body, and environment all play integral roles in shaping our emotional experiences. By understanding the neural and functional correlates of consciousness and emotion, we can gain insights into the potential markers of conscious emotion in both humans and animals.

The role of the brain's intrinsic activity in emotional feeling

The intrinsic activity of the brain and its role in emotional feeling is a topic that has been explored in recent years, with a focus on understanding the neural and information processing functions associated with consciousness. This area of research aims to identify the neural correlates of consciousness (NCCs) and how they relate to emotional feelings. The following sections will discuss the role of the brain's intrinsic activity in emotional feeling, including its potential markers and implications for animal consciousness.

Neural and Information Processing Functions of Consciousness

The search for neural correlates of consciousness (NCCs) in humans has been a growing area of research, with a range of candidate NCCs proposed. These theories often identify an information processing function implemented in a specific neural substrate as the "minimally sufficient" condition for conscious experience. The distinction between the information processing function and the neural substrate is important when considering the implications of NCC theories for animal consciousness.

Global Workspace Theory

Global Workspace Theory (GW Theory) posits that consciousness arises from the broadcasting of selected information across a network of modular processors. It suggests that isolated modules operate automatically and unconsciously, while the global workspace allows for integrated and flexible behavioural coordination. The neural substrate of the global workspace is proposed to be fronto-parietal association areas with widespread connections.

Integrated Information Theory

Integrated Information Theory (IIT) focuses on the amount of "integrated information" in a system rather than a specific mechanism. It suggests that consciousness is a continuous variable, with higher values indicating more consciousness. IIT does not tie consciousness to a specific mechanism or neural substrate, allowing for a broader view of animal consciousness.

Higher-Order Theories of Consciousness

Higher-Order Theories of Consciousness (HOT and HOE) propose that a first-order representation becomes conscious only when it is the object of a higher-order representation. Different variants of the theory differ in the properties they attribute to the higher-order representations. Some proponents argue that higher-order representations need not be as sophisticated, allowing for the possibility of simpler forms in animal consciousness.

The brain's intrinsic activity, or resting-state activity, has been found to be closely related to emotions. Resting-state activity in midline regions, such as the ventromedial prefrontal cortex (VMPFC) and other anterior cortical midline structures (aCMS), has been associated with emotional feelings. These regions show strong convergence between intero- and exteroceptive inputs, as well as the brain's high intrinsic activity.

Empirical Studies on the Role of Intrinsic Activity

Several empirical studies have investigated the relationship between resting-state activity and emotions. One study found that sad faces induced higher deactivation in midline regions compared to happy faces, while another study found that emotional measures correlated with signal changes in the VMPFC, dorsomedial prefrontal cortex (DMPFC), and posterior cingulate cortex (PCC) during rest and exteroceptive awareness. These findings suggest that the brain's intrinsic activity plays a crucial role in emotions and emotional feelings.

Implications for Animal Consciousness

The search for neural and functional correlates of consciousness in animals is challenging due to the lack of direct methods for establishing the presence of conscious experiences. However, by combining animal-focused approaches with investigations of the components of conscious and non-conscious emotional processing in humans, it may be possible to identify potential markers of conscious affective processing in animals.

The relationship between emotional feeling and phenomenal consciousness

Emotions are an integral part of our lives, influencing our thoughts, actions, and decisions. However, the relationship between emotions and consciousness remains a complex and enigmatic topic. In this article, we will explore the intricate link between emotional feelings and phenomenal consciousness, delving into the latest research and theories to gain a deeper understanding.

Emotional Feelings and their Neural Correlates

Emotional feelings are multifaceted experiences that involve various components such as physiological changes, behavioural responses, and cognitive processes. The conscious experience of emotions, often referred to as "feelings," is a crucial aspect of this multifaceted experience. However, the question of whether non-human animals share this conscious experience of emotions remains a subject of debate.

To understand the relationship between emotional feelings and phenomenal consciousness, it is essential to consider the neural correlates of emotions. The limbic system, including the amygdala, hippocampus, and hypothalamus, plays a significant role in generating and regulating emotions. These brain structures are part of our fast-acting automatic survival network and are responsible for processing emotional responses and memories.

The Role of the Environment in Emotional Feelings

While the body's sensorimotor functions and vegetative states have long been recognized as crucial in constituting emotional feelings, recent theories propose a more direct and constitutive role for the environment. This "relational concept" of emotional feeling suggests that the environment itself plays a fundamental role in shaping our emotional experiences, independent of the body's representations.

The Intrinsic Linkage Between Emotional Feelings and the Social Environment

The concept of "existential feelings" highlights the idea that our emotional experiences are deeply intertwined with our relationship to the world. These feelings reflect our ways of "finding ourselves in the world" and are influenced by our interactions with the social environment. This perspective aligns with the idea that emotions are fundamentally relational and dependent on our connections with others.

The Subjective Nature of Emotions

Emotions are inherently subjective and private experiences. This subjectivity is closely linked to the brain's intrinsic activity, particularly the resting-state activity. Research has shown that emotions are associated with specific midline regions in the default-mode network, which exhibit high levels of resting-state activity. Furthermore, the impact of emotions on subsequent resting-state activity has also been observed, indicating a dynamic interplay between emotions and the brain's intrinsic activity.

The Neural-Intero-Exteroceptive Relational Model of Emotional Feelings

The neural-intero-exteroceptive relational model proposes that emotional feelings arise from the interaction between interoceptive stimuli (changes in our body) and exteroceptive stimuli (changes in our environment). This model suggests that emotions are shaped by the relationship between our body, our environment, and our brain's intrinsic activity.

The Role of Consciousness in Emotional Feelings

Consciousness, particularly phenomenal consciousness, is essential for fully experiencing emotions. The relational approach to emotional feelings emphasizes the role of the environment and our relationship with it. This perspective challenges the traditional view of emotions as solely dependent on the body and its sensorimotor functions. Instead, it suggests that emotions are fundamentally relational and influenced by our interactions with the world.

The relationship between emotional feelings and phenomenal consciousness is complex and multifaceted. While emotions consist of various components, the conscious experience of emotions, or "feelings," is a crucial aspect. The environment plays a direct and constitutive role in shaping our emotional experiences, and the brain's intrinsic activity, particularly resting-state activity, is intimately linked to the subjective nature of emotions. The neural-intero-exteroceptive relational model proposes that emotions arise from the dynamic interplay between interoceptive and exteroceptive stimuli, modulated by the brain's intrinsic activity.
