Define epsp and ipsp

WebThe simultaneous summation of EPSP and IPSP also helps to regulate synaptic transmission and neuronal activity. Facilitation of Neuron. Another important phenomenon associated with summation is the facilitation of neurons. Sometimes, the summated postsynaptic potential is excitatory but is below the threshold level. In this case, the … WebSince the equilibrium potential of K + ions is more negative than the resting membrane potential, the opening of K + channels gives rise to an outward current (an exit of positive charges) and to a hyperpolarization of the membrane; i.e. an IPSP. If this IPSP is concomitant with an EPSP, it will reduce the amplitude of the EPSP.

WebIn simple terms, EPSP creates an excitable state at the post-synaptic membrane that has the potential to fire an action potential whilst IPSP creates a less excitable state that inhibits the firing of an action potential by the post-synaptic membrane. This is the key difference between EPSP and IPSP. WebEPSP (excitatory postsynaptic potential) is a temporary depolarization of postsynaptic membrane caused by the flow of positively charged ions into the postsynaptic cell as a …

WebEPSP is due to influx of sodium ion. If IPSP is produced, postsynaptic region becomes hyperpolarized and hence there will not be development of action potential in postsynaptic region. IPSP will be due to efflux of potassium ions or influx of chloride ions at postsynaptic regions. Properties of Synapse: 1.
