title: Vestibular end organ mapping in the squirrel monkey.
abstract: Vestibular end organ mapping (surface preparation) was performed in squirrel monkeys by using succinic dehydrogenase staining. Comparing sensory hair cell counts and surface area measurements of the squirrel monkey to those of man and the guinea pig, the values obtained from the squirrel monkey were between those of man and the guinea pig. When regional (central versus peripheral) cell density was compared, the density of the peripheral area was 1.62X more on the average than that of the central portion.
