Correct Answer: Microelectrode
Description: Ans: C i.e. MicroelectrodeSynaptic potential/Postsynaptic potentialIt is a change in the potential, voltage, of the post synaptic cell.It is an alteration in the membrane potential of a cell resulting from activation of a synaptic input.All animal cells maintain a voltage difference between the intracellular and extracellular regions, holding the intracellular region at a negative voltage that in a baseline state is ur"<> in the range -30 to -70 millivolts.Synaptic inputs from neurons can alter this voltage difference.If the intracellular voltage rises, the signal is called an excitatory postsynaptic potential (EPSP); if it falls the signal is called an inhibitory postsynaptic potential (IPSP).If the cell is electrically excitable, a sufficiently large EPSP may cause it to generate an action potential.
