Which of the following statements is false?
  a. Synaptic potentials may vary in magnitude.
  b. Synaptic integration sums arriving signals over
  space and time.
  c. An excitatory postsynaptic potential is
  hyperpolarizing, whereas an inhibitory
  postsynaptic potential is depolarizing.
  d. Synaptic integration means that signals arriving
  at a neuron can be reinforced or dampened.
  e. Synaptic integration means that signals arriving
  at a neuron can be sent on or suppressed.

Question 2

  c. excitatory and inhibitory signals are summed in
