Abstract from:
Chance, F.S. & Abbott, L.F. Input-Specific Adaptation in Complex
Cells through Synaptic Depression. (2001) Neurocomputing 38-40: 141-146.
A number of experiments have reported that neurons in primary visual
cortex can adapt in a stimulus-dependent manner. Synaptic depression is
a plausible mechanism for this type of adaptation because its synapse specificity
allows modification of particular inputs while allowing others to remain
unaffected. Furthermore, a form of synaptic depression measured in slice
experiments sets in and recovers over appropriate time scales to account
for such an effect. We show that synaptic depression on feedforward, but
not on recurrent, inputs can produce a fast form of spatial-phase-specific
adaptation in a complex cell model.
