Final answer:
The skill of inhibitory control involves the voluntary suppression of unwanted responses and is governed by the somatic nervous system, which requires complex neural interactions, including GABA(A) receptors activation.
Step-by-step explanation:
The voluntary suppression of unwanted responses is a skill of inhibitory control. This type of response control is voluntary or conscious and is governed by the somatic nervous system. Examples of inhibitory control in the nervous system include the suppression of gland secretions and the inhibition of cardiac muscle to decrease heart rate and stroke volume. These actions represent a complex interaction between the sensory input, central processing within the nervous system, and the motor output that results in controlled muscle movements and glandular functions.
One neurobiological mechanism of inhibitory control is the activation of GABA(A) receptors, which can produce both phasic and tonic inhibitory effects on neurons, thereby regulating responses. Phasic activation results in brief bursts of inhibition, whereas tonic activation produces a continual inhibitory tone that shapes neural excitability. Disinhibition, which is a related concept, occurs through a disynaptic connection where the first synapse inhibits a second cell, which then stops inhibiting the final target, thus allowing for a controlled response.
