Can you think of situations in which it would be important for the dendrite of the postsynaptic neuron to be stimulated (EPSP- excitatory postsynaptic potential)? To be inhibited (IPSP- inhibitory postsynaptic potential)? What types of problems might occur if it was not possible to control whether postsynaptic neurons were inhibited or stimulated? For example, what if postsynaptic neurons were always stimulated?
