Question

Quizplus · Accepted Answer

Neural integration refers to the process by which the nervous system combines and processes information from multiple sources, including sensory inputs and internal states. The basis of this integration is the summation of postsynaptic potentials (PSPs) that occur in overlapping time and space. PSPs can be either excitatory or inhibitory and can add together to create a net effect that determines whether a neuron will fire an action potential or not. This process is known as temporal and spatial summation. Therefore, choice A, which describes the addition of PSPs overlapping in time and space, is the best choice.
