[Convergence of signals on neurons of the anterior hypothalamus during local thermal stimulation of the skin].
Changes in the mean firing rates of the preoptic and septal neurons under thermal stimulation of different skin areas were studied in unanesthetized rabbits. The skin temperature of the rabbit back (skin area I) or face (skin area II) was increased to 38-40 degrees C or decreased to 22-26 degrees C. Out of 111 units under study 21 units responded to changes in the skin temperature. All thermosensitive hypothalamic neurons responded to thermal stimulation of both skin areas. Different types of neuronal responses are described.
