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

The concentration of voltage-gated sodium channels is actually highest at the axon hillock, not the dendrites of the postsynaptic cell. This is important for the initiation of action potentials.
