Abstract:Purkinje neurons are the unique output of the cerebellar cortex, and the inputs mainly come from climbing fibers and parallel fibers from olivary nucleus and granule cells. Based on the anatomic model, which is very similar to the real neural system, this paper analyzed the Phase Response Curve (PRC) of three different neurons (Purkinje neurons, granule neurons, climbing fibers) and classified their neural excitatory by comparing their fI curves, and then further studied the synchronization in this circuit by changing the synaptic conductance and CaP conductance principally. The analysis results show that the synchronization is very significant in the information transfer.
