TRUE, The presynaptic and postsynaptic membranes are firstly clearly separated from one another. The synaptic cleft is the term for the space separating the two.
The statement is true
The postsynaptic dense (PSD), which is often found near the apex of the dendritic spine, is a structural and physiological specialization of postsynaptic membrane that characterizes excitatory synapses.
Neurotransmitters that have been released into the synaptic cleft interact to receptor proteins on the postsynaptic cell's membrane, causing the membrane's ionic channels to either open or close. Another action potential starts whenever these channels open, which causes depolarization.
