If one nerve stimulus arrives
WebA single axon can have multiple branches, allowing it to make synapses on various postsynaptic cells. Similarly, a single neuron can receive thousands of synaptic inputs … WebIf two action potentials invade an axon terminal 10 msec apart, this can actually result in more transmitter being released on the second pulse than on the first pulse. This is called "short-term facilitation." On the flip side, axon terminals can deplete their stores of neurotransmitter if exposed to persistent, high-frequency activity.

WebIf the neurotransmitter is excitatory, the influx of positive ions will depolarize (bring closer to zero) the cell body. If the neurotransmitter is inhibitory, it will hyperpolarize the cell body. … WebMay 18, 2007 · The first is the mean threshold m k, which is the stimulus at which a motor unit has a 50% probability of firing and determines the horizontal location of the excitability curves that are shown in Figs 2(c) or 2(d). In setting a prior for m we require one that gives economical values for the number of units, N.
