Disinhibition

 

the abolition of internal inhibition in the cortex of the brain’s large hemispheres under the influence of a new, extraneous stimulus.

The concept of disinhibition was introduced by I. P. Pavlov. Excitation arising at a point on the cortex of the large hemispheres under the influence of an extraneous stimulus radiates through the cortex, takes over other points of the cortex, including inhibited ones, and abolishes the inhibition, transforming it to excitation. For example, a conditioned food reflex abolished by repeated use of a conditioned stimulus unaccompanied by an unconditioned one (that is, not reinforced with food), manifests itself as soon as a new, previously unused stimulus is added to the conditioned stimulus. Disinhibition may also result from positive induction. The phenomenon of disinhibition may also be observed in other parts of the central nervous system.
