Expert Answer:

  • If glycine is released from the pre-synaptic membrane, the membrane of post synaptic neuron has two types of ion channels-excitatory and inhibitory.
  • The excitatory channels are those which are specific to sodium ions and inhibitory channels are those which are specific to chloride ions.
  • The flow of sodium ions into the cell causes a membrane potential called excitatory postsynaptic membrane potential (EPSP) whereas the flow of chloride ions causes an inhibitory postsynaptic membrane potential (IPSP).
  • If the synapse is excitatory, Sodium ions flow into the cell resulting into positive current. 
  • If the synapse is inhibitory, chloride ions move into the cell, resulting into negative current.
