(B) A neocortical pyramidal neuron has thousands of excitatory synapses located on dendrites (inset). The co-activation of a set of synapses on a dendritic segment will cause an NMDA spike and depolarization at the soma. WebSynapses are microscopic gaps that separate the terminal buttons of one neuron from receptors (usually, located on the dendrites) of another neuron. When neurons communicate, they release chemicals that must travel across this gap to stimulate the post-synaptic receptors.
