Outline of Final Research Achievements |
To elucidate whether and how the local brain temperature affects perception, we measured the somatosensory evoked potentials (SEPs) while varying the cortical temperature. The amplitudes of SEPs increased when the cortical temperature decreased from 38 to 27.5 °C when no antagonist was administered. The negative correlation was plateaued after administering a GABA(A) receptor antagonist. In contrast, the correlation remained negative after administering an AMPA or NMDA receptor antagonist. These results suggest that GABAergic inhibitory inputs contribute to the negative correlation around the physiological cortical temperature.
