WHAT IS SYNAPTIC PLASTICITY?

PLASTICITY IS THE ABILITY OF THE BRAIN TO CHANGE AND ADAPT TO NEW INFORMATION. SYNAPTIC PLASTICITY IS THE ABILITY OF SYNAPS TO STRENGTHEN OR WEAKEN OVER TIME,IN RESPONSE TO INCREASE OR DECREASE IN THEIR ACTIVITY.SYNAPTIC PLASTICITY IS CHANGE THAT OCCURS AT SYNAPS, THE FUNCTION BETWEEN NEURONS THAT ALLOW THEM TO COMMUNICATE.

Function of synaptic plasticity:-

SYNPTIC PLASTICITY CONTROLS HOW EFFECTIVELY TWO NEURONS COMMUNICATE WITH EACH OTHER.

LONG-TERM POTENTIATION:-

LONG-TERM POTENTIATION, COMMONLY REFERRED TO AS LTP,IS AN INCREASE IN SYNAPTIC RESPONSE FOLLOWING POTENTIATING PULSE OF ELECTRICAL STIMULI THAT SUSTAINS AT A LEVEL ABOVE THE BASE LINE RESPONSE FOR HOURS OR LONGER.LTP INVOLVES INTERACTION BETWEEN POSTSYNAPTIC NEURONS AND THE SPECIFIC PRESYNAPTIC

INPUTS THAT FORM A SYNAPTIC ASSOCIATION, AND IS SPECIFIC TO THE STIMULATED PATHWAY

OF SYNAPTIC TRANSMISSION.

SHORT-TERM POTENTIATION:-

IT IS THE BIOLOGICAL PROCESS BY WHICH SYNAPTIC TRANSMISSION IS TRANSIENTLY ENHANCED, USUALLY AS A RESULT OF AN INCREASE  IN SYNAPTIC VESICLE, RELEASE PROBABILITY PAIRED PULSE FACILITATION IS A WELL KNOWN FORM OF STP.
