Normal changes of the aging brain include:
a. increased velocity of nerve conduction.
b. diminished perception of touch.
c. increased total number of neurons.
d. diminished intelligence quotient.
B
Sensory perceptions of touch and pain are diminished by aging. The velocity of nerve impulse conduction declines, so responses to stimuli take longer. The number of cerebral neurons is thought to decrease by 1% a year, beginning at 50 years of age; however, the vast number of re-serve cells inhibits the appearance of clinical signs.
