Popis: Changes in the mean firing rate of posterior hypothalamic neurons were studied in experiments on unanesthetized cats in response to elevation of the brain temperature by 0.7–1.5°C and the skin temperature by 3–5°C separately or simultaneously. Altogether 85 neurons were studied in 14 animals: 11 responded to only one form of temperature stimulation, whereas in 16 neurons changes in the firing pattern (in most cases in the same direction) were observed in response to both forms of temperature stimulation. Different types of responses of these neurons were established. Sensitivity to the central temperature stimulus was increased in some neurons of this group when skin temperature stimulation was intensified.
