Outline of Final Research Achievements	To examine the functional properties of cortical pain-related areas, we recorded neuronal responses to the thermal stimuli in the frontal lobe and the primary somatosensory cortex of two Japanese monkeys. In the ventral premotor cortex, neurons responded most strongly when monkeys detected changes in the temperature. This suggested the involvement of the ventral premotor neurons in the process of perceptual decision on slight changes in the temperature. Neurons in the primary somatosensory cortex also responded to the heat stimuli.
