        Complex, integrated electrical patterns rather than just the presence of a specific chemical.

        The measure of electrical activity in the motor cortex (visible via EEG) that builds up milliseconds before a person makes a conscious, voluntary movement. It’s distinct from the sharp spike of a reflex.

        If the action originates from the Prefrontal Cortex (executive function/planning), it’s generally considered “conscious effort.” If the signal bypasses the cortex and stays in the brainstem or spinal cord, it’s a reflex.
