WebFeb 9, 2024 · It is an electrical charge that occurs within the post-synaptic membrane of the neuron as a result of excitatory neurotransmitters. EPSP creates an exciting environment within the post-synaptic membrane. This excitation results in the firing of an action potential. IPSP is referred to as inhibitory postsynaptic potential. WebC, Temporal summation occurs when a series of subthreshold EPSPs in one excitatory fiber produce an AP in the postsynaptic cell. This occurs because the EPSPs are superimposed on each other temporally before the local region …

WebJul 7, 2024 · Summation of postsynaptic potentials occurs when a presynaptic neuron fires repeatedly at a high rate (“temporal summation”)or when several presynaptic terminals fire at the same time (“spatial summation”) or from a combination of temporal and spatial summation. What do you mean by summation? WebApr 11, 2024 · The postsynaptic potentials are subject to summation which means that they can be added. They can summed up spatially i.e. in a particular region or temporally i.e. during a particular time. The summations are explained as follows: WebSpatial summation uses multiple synapses acting simultaneously.

WebFeb 14, 2024 · Temporal summation – this happens when all the postsynaptic potentials occur in the same place but at slightly different times. For example, if there are two single excitatory signals (EPSPs) that arrive at the postsynaptic neuron from two different dendrites, they cannot reach the threshold for action potential on their own. WebSimple temporal summation of postsynaptic potentials occurs in smaller neurons, whereas in larger neurons larger numbers of synapses and ionotropic receptors as well as a longer distance from the synapse to the soma enables the prolongation of interactions between neurons.
