Answer 1

The basis of neural integration is the linear addition of postsynaptic potentials overlapping in time and space, which determines whether an action potential will be initiated in the postsynaptic neuron.

Step-by-step explanation:

The basis of neural integration is the linear addition of postsynaptic potentials overlapping in time and space. This means that when multiple presynaptic inputs create excitatory postsynaptic potentials (EPSPs) at the same time and at the same place on a neuron, these potentials add up and can reach the threshold to initiate an action potential in the postsynaptic neuron. Additionally, inhibitory postsynaptic potentials (IPSPs) can cancel out EPSPs, regulating the net change in postsynaptic membrane voltage.
