title: Responses of lateral hypothalamic neurons recorded in vitro to moderate changes in glucose concentration.
abstract: Single unit neuronal activity of lateral hypothalamic neurons was recorded extracellularly in hypothalamic slices. Glucose concentration in the perfusate was modified in small amounts to simulate normal physiological glycemic fluctuations associated with feeding. Several neurons responded reliably under these conditions. These data on simulated small glycemic changes, based on observations in the whole animal, suggest that the modulation of neuronal activity reported in this study is a result of a direct action of glucose on cells in this region of the hypothalamus.
