Active inference and cognitive-emotional interactions in the brain

Area of Science:

• Neuroscience
• Cognitive Science
• Computational Psychiatry

Background:

• Active inference provides a unified framework for understanding goal-directed behavior.
• Cognition, emotion, and motivation are crucial for navigating the environment and achieving desired states.

Purpose of the Study:

• To elucidate the integrated mechanisms of cognition, emotion, and motivation within the active inference framework.
• To explore the role of signal processing and neuronal tuning in guiding action.
• To highlight the potential psychopathological consequences of dysregulated integration.

Main Methods:

• Bayesian fusion of exteroceptive, proprioceptive, and interoceptive signals.
• Precision-weighting of prediction errors.
• Affective tuning of neuronal representations.

Main Results:

• Demonstrated how integrated sensory signals and prediction error modulation guide action selection.
• Showcased the mechanism of "affective tuning" in neural processing.
• Linked disruptions in these processes to potential psychopathological outcomes.

Conclusions:

• Active inference offers a comprehensive model for understanding the interplay of cognition, emotion, and motivation.
• Aberrant integration and processing of internal and external signals are implicated in mental health disorders.
• Further research into these mechanisms can inform therapeutic strategies for psychopathology.
