Physiology of free will.

Area of Science:

• Neuroscience
• Philosophy of Mind

Background:

• The common perception of free will suggests individuals consciously choose their actions.
• This sense of agency involves willing movement and responsibility for it.

Purpose of the Study:

• To investigate the neurological basis and timing of the perception of free will.
• To determine if a "free will force" precedes voluntary movement.

Main Methods:

• Review of existing neurological and psychological research on voluntary action and decision-making.
• Analysis of the temporal relationship between neural activity, movement execution, and the subjective experience of willing.

Main Results:

• No evidence supports a "free will force" preceding movement initiation.
• The perception of willing an action is processed after the movement has begun.
• Perceptions of free will likely emerge from integrated activity in frontal and parietal brain regions.

Conclusions:

• The subjective experience of free will is not a direct cause of movement but rather an interpretation generated post-hoc.
• Free will, as a perception, may be considered to exist when the brain operates without external coercion or dysfunction.
