Post by: fstiles93 on Mar 29, 2018
Since all action potentials are identical, the intensity of a sensation depends on:
  a. whether a myelinated or unmyelinated neuron has been stimulated.
  b. the duration of the stimulation.
  c. whether the neuron stimulated is a pre- or postsynaptic neuron.
  d. the total number of neurons stimulated and the frequency of their discharge.
  e. the presence of an EPSP or IPSP, which allows for a graded response.

Question 2

What is a characteristic of the all-or-none response?
  a. If a stimulus is strong enough, all axons in a nerve bundle will fire simultaneously.
  b. A neuron will only produce an action potential if it has been depolarized to its threshold level.
  c. All neurons of a nerve bundle discharge impulses at the same frequency.
  d. A neuron can create an action potential of varying intensities.
  e. Either all or none of the neurons of a brain region will fire impulses when stimulated.
