Synaptic augmentation
Augmentation is one of four components of short-term synaptic plasticity that increases the probability of releasing synaptic vesicles during and after repetitive stimulation such that A ( t ) = [ T r a n s m i t t e r R e l e a s e ( t ) / T r a n s m i t t e r R e l e a s e ( 0 ) ] − 1 , {\displaystyle A(t)=[{\rm {TransmitterRelease}}(t)/{\rm {TransmitterRelease}}(0)]-1,} when all the other components of enhancement and depression are zero, where A {\displaystyle A} is augmentation at time t {\displaystyle t} and 0 refers to the baseline response to a single stimulus. The increase in the number of synaptic vesicles that release their transmitter leads to enhancement of the post synaptic response.
