Summatsiya excitation (or inhibition) .Nervnye centers can summarize the afferent impulses, resulting in a strengthening of synthroid buy
the reflex by increasing the frequency of stimulation or annoyed receptors. There are two types of summation: temporal summation - if the pulses come to neuron on the same path through a synapse with a short interval, the EPSP proiskhoditsummirovanie on postsiiapticheskoy membrane and it is depolarized to a level sufficient for the generation of PD; spatial summation associated with the summation of EPSP occurring simultaneously in different synapses of a single neuron. Both species occur in the summation region of the axon hillock, where accutane buy
PD is generated.
