The changes in thermal preference, sleep-wakefulness, body temperature and locomotor activity in the rats with medial septal lesion

It can, therefore, be concluded that the MS lesion affected the initiation of SWS, as there was a decrease in the frequency of SWS episodes. Study of S-W in the rats that were given freedom to select Tamb helped to demonstrate the role of the MS in the inhibition of PS. It also showed that the thermostat of the rats was reset at a lower level by the third week after the MS lesion. Decrease in heat production resulting from a decrease in LMA, could have contributed towards the animals' efforts to maintain a lower Tb.
