Answer: This addition and response to the net effect of postsynaptic potentials is called SPATIAL SUMMATION. Option C is correct..
Explanation: Spatial summation is the effect of triggering an action potential in a neuron from one or more presynaptic neurons. This occurs when more than one excitatory postsynaptic potential (EPSP) originates simultaneously and a different part of the neurone.
This addition and response to the net effect of postsynaptic potentials is known as spatial summation.
• A mechanism of provoking an action potential in a neuron with input from several presynaptic cells is known as spatial summation.
• It is the algebraic addition of potentials from distinct regions of input, generally on the dendrites.
• The EPSPs summation or the excitatory postsynaptic potentials summation enhances the chances of the potential to attain the threshold potential and produce an action potential. On the other hand, the IPSPs or inhibitory postsynaptic potentials summation can inhibit the cell from attaining an action potential.
Thus, the correct answer is option c, that is, spatial summation.
