Lecture on the topic:
"Cortical inhibition. Types
of higher nervous activity"
, Inhibition of reflexes
There are :
1) unconditional reflexes
(external);
l 2) conditional reflexes (internal).
,Unconditioned inhibition
This type of reflexes inhibition
occurs immediately in response
to the action of an external
stimulus, that is, it is an innate,
unconditioned form of inhibition.
The biological meaning of the
unconditioned (external)
inhibition of conditioned reflexes
is a reaction to the main, most
important stimulus for the
organism at a definite time
simultaneously suppressing the
reaction to a secondary stimulus,
which in this case is a conditional
stimulus.
, Simple inhibition
This is an extremely
common type of inhibition
that constantly takes
place in the life of both
animals and humans. This
inhibition is expressed in
the termination of the
current reaction under
the influence of the
sudden action of an
external stimulus. For
example, an animal has
developed a conditioned
food reflex to light: the
experimenter turns on the
electric light bulb, and
the dog begins to salivate.
At this time, a loud sound
is heard and conditioned
salivation stops. The
reaction is interrupted,
stopped – inhibited.
