Labyrinthine Input to the Vestibular Nuclei and Reticular Formation
The behavior of neurons within the central nervous system in response to vestibular stimulation, particularly natural stimulation, has been under investigation for some time. Adrian (1943), in pioneering studies, was the first to record the activity of neurons in the mammalian vestibular nuclei. Working in the cat, he studied neurons that were sensitive to linear or to angular acceleration. In more recent years, vestibular physiology was provided an important stimulus by the detailed, functionally oriented anatomical studies of Brodai and his collaborators, and of others. These studies may be said to have led to investigations of the central connections of vestibular afferents, and of the behavior of second- and higher- order neurons in response to electrical stimulation of the vestibular nerve and to natural stimulation of the labyrinth. Excellent examples of this work, which began to appear in the middle 1960s, are the various elegant studies of Shimazu and Precht that will be described below.
