Gamma --> beta frequency shift in the circuits with strongly facilitating synapses.
Joanna Jędrzejewska-Szmek (Faculty of Physics, University of Warsaw)
Synapses exhibiting strong elevation of postsynaptic response due to paired pulse stimulus have been reported in literature . Hereby we investigate the role of strongly facilitating synapses  in neural circuits. Using the non-linear short term facilitaion model presented in  and formalism developed in , we derive a Wilson-Cowan model of strongly facilitating synapse. Then we investigate the possible role of excitatory strong facilitating synapse [1,2] between the excitatory and inhibitory population, showing that it can play an important role in beta --> gamma frequency shift and possible generation of beta rebound, that can be seen in Figure below.
