Summary
This study introduces a three-dimensional model linking neural activity to phenomenal experience and behavior. It proposes distinct neural units for psychomotor, affective, and thought dimensions, explaining their roles in health and neuropsychiatric disorders.
Area of Science:
- Neuroscience
- Psychiatry
- Physiology
Background:
- Understanding the link between phenomenal experience, behavior, and neural activity is crucial in neuroscience and psychiatry.
- Phenomenal-behavior patterns can be categorized into psychomotricity, affectivity, and thought, each potentially having unique neural correlates.
- Existing research explores these dimensions across various physiological and pathological conditions.
Purpose of the Study:
- To provide a data overview on the relationship between phenomenal-behavioral dimensions and brain activity.
- To propose a novel three-dimensional model of neural activity and phenomenal-behavioral patterns.
- To elucidate the neural underpinnings of psychomotricity, affectivity, and thought in both healthy and disordered states.
Main Methods:
- Data overview across physiological and pathological conditions.
- Development of a three-dimensional model of neural activity.
- Analysis of neural units (external, internal, associative) and their relation to phenomenal-behavioral dimensions.
Main Results:
- A three-dimensional model is proposed, organizing neural activity into external, internal, and associative units.
- The external unit relates to sensorimotor networks and the psychomotor dimension.
- The internal unit relates to the salience network and the affective dimension, while the associative unit relates to default-mode networks and the thought dimension.
Conclusions:
- Neural activity is organized into distinct units (external, internal, associative) corresponding to psychomotor, affective, and thought dimensions.
- Hyperactivity or hypoactivity in these neural units correlates with specific manifestations in psychomotricity, affectivity, and thought.
- These neural units dynamically interplay, explaining complex phenomenal experiences and behaviors in health and neuropsychiatric disorders.
