WebBasically, a postsynaptic neuron adds together, or integrates, all of the excitatory and inhibitory inputs it receives and “decides” whether to fire an action potential. The integration of postsynaptic potentials that occur in different locations—but at about the same time—is known as spatial summation. WebThermoreceptors are of two types, warmth and cold. Warmth fibres are excited by rising temperature and inhibited by falling temperature, and cold fibres respond in the opposite manner. Mechanoreceptors are also of several different types.
