Intercalated cells of the amygdala mPFC) in both primates and rodents, which may explain cortical control over emotional regulation processes such as extinction. Intercalated cells of the amygdala The intercalated (ITC) cells of the amygdala are a group of GABAergic neurons situated between the basolateral and central nuclei of the amygdala that are important for inhibitory control over the amygdala. ITC cells are thought to play a role as the 'off switch' for the amygdala, inhibiting the amygdala's central nucleus output neurons and its basolateral nucleus neurons. Some researchers speculate that ITC cells, via their extensive local inhibition within the amygdala, could serve as a
Action potential potential. Their joint efforts can be thwarted, however, by the counteracting inhibitory postsynaptic potentials. Neurotransmission can also occur through electrical synapses. Due to the direct connection between excitable cells in the form of gap junctions, an action potential can be transmitted directly from one cell to the next in either direction. The free flow of ions between cells enables rapid non-chemical-mediated transmission. Rectifying channels ensure that action potentials move only in one direction through an electrical synapse. Electrical synapses are found in all nervous systems, including the human brain, although they are a distinct minority. The amplitude of an action
