In unanesthetized rats, neuronal activity in the lateral hypothalamic area was recorded during horizontal and head-down tilt suspension. When the rat was raised in the horizontally suspended position, 21 of 44 neurons changed activity as follows: immediate increase (7/21, Type I), immediate decrease (3/21, Type II), and gradual decrease (11/21, Type III). When the rat was raised with a head-down tilt position, the responses were suppressed in about half of the neurons tested. These results showed that the LHA neurons altered their activity in response to low G simulation induced by body suspension. Possible signals which induce the changes in the LHA neuronal activity, and an involvement of the LHA in the autonomie reflexes under hypogravic condition are discussed.
