In a sequence of two talks, this is the second where we discuss synchronous behaviors in neurons. The topic is of relevance to a number of neurological situations including Parkinson's disease, depression, circadian rhythms and motor pattern generators. Our numerical simulations indicate how the coupling (synapses) between neurons can lead them to synchronize, or not, depending on the dynamical states of the individual neurons and on the type and strength of the couplings. In addition, we extend the single-compartment Huber-Braun neuron model equations to include soma, axon and dendrites. This multi-compartment model has yielded promising preliminary results, consistent with experimental data obtained from the neural stomatogastric system of crustaceans like the crab.
