a. occurs when membrane-bound synaptic vesicles are released from thepresynaptic cell and then fuse with the plasma membrane of thepostsynaptic cell.b. requires the release of calcium ions from the postsynaptic cell.c. is required f<strong>or</strong> excitat<strong>or</strong>y neurotransmission but not f<strong>or</strong> inhibit<strong>or</strong>yneurotransmission.d. all of the abovee. none of the above26. The recept<strong>or</strong> potential of a primary sens<strong>or</strong>y neuron:a. is another name f<strong>or</strong> the action potential in a primary sens<strong>or</strong>y neuron.b. is the change in membrane potential resulting from the process of sens<strong>or</strong>ytransduction.c. is stimulated by synaptic inputs from other primary sens<strong>or</strong>y neurons.d. all of the above are c<strong>or</strong>rect.e. none of the above is c<strong>or</strong>rect.27. The primary somatosens<strong>or</strong>y c<strong>or</strong>tex:a. is located in the postcentral gyrus, just behind the central sulcus of thecerebral c<strong>or</strong>tex.b. is <strong>or</strong>ganized in a somatotopic map, with sens<strong>or</strong>y inputs from the headrepresented nearest the midline and inputs from the feet at the most lateralposition.c. receives direct synaptic input from primary sens<strong>or</strong>y neurons, without anyintervening synapses.d. on the right side of the brain receives sens<strong>or</strong>y inf<strong>or</strong>mation from the rightside of the body.e. receives sens<strong>or</strong>y inf<strong>or</strong>mation only from the d<strong>or</strong>sal column pathway of thespinal c<strong>or</strong>d.28. In the retina:a. phot<strong>or</strong>ecept<strong>or</strong>s depolarize in response to illumination.b. light is abs<strong>or</strong>bed in rod phot<strong>or</strong>ecept<strong>or</strong>s by the visual pigment molecule,rhodopsin.c. center-surround receptive fields are observed only in retinal ganglion cells.d. all of the abovee. none of the above29. The primary audit<strong>or</strong>y c<strong>or</strong>tex:a. receives direct synaptic inputs from the cochlear nucleus, withoutintervening synapses.b. is located in the frontal lobe of the cerebral c<strong>or</strong>tex.c. is <strong>or</strong>ganized in a two-dimensional array of vertically <strong>or</strong>iented frequencycolumns and binaural columns.d. all of the abovee. none of the above30. The olfact<strong>or</strong>y bulb:a. receives olfact<strong>or</strong>y inputs from the thalamus, which in turn receives directsynaptic input from the axons of primary olfact<strong>or</strong>y recept<strong>or</strong> neurons.b. receives synaptic inputs from the glomeruli of the olfact<strong>or</strong>y paleoc<strong>or</strong>tex.
