Which of the following statements regarding synapses is incorrect? A. When a second EPSP (excitatory postsynaptic potential) arrives at a single synapse before the effects of the first have disappeared spatial summation occurs. B. An action potential occurs if the excitatory effect is greater than the inhibitory effect and the membrane voltage reaches threshold. C. A postsynaptic potential is a graded potential that can be the result of a neurotransmitter released into the synapse between two neurons. D. An inhibitory postsynaptic potential (IPSP) is associated with hyperpolarization.

When a second EPSP (excitatory postsynaptic potential) arrives at a single synapse before the effects of the first have disappeared, spatial summation occurs. - This statement is correct. Spatial summation occurs when multiple EPSPs arrive at a synapse at the same Show more…

29. Which of the following statements about the process of summation in a neuron is FALSE? A. Spatial summation adds up the simultaneous influences of synapses at different locations on the postsynaptic cell. B. The concentration of voltage-gated sodium channels is highest in the dendrites of the postsynaptic cell. C. Axons that terminate closer to the axon hillock have more influence on the summation process than those that do not. D. The process is essentially a comparison of all the excitatory and inhibitory postsynaptic inputs. E. Slight perturbations of the membrane potential spread across the postsynaptic cell body.
