Food deprivation does not potentiate glucose taste reactivity responses of chronic decerebrate rats


, : Food deprivation does not potentiate glucose taste reactivity responses of chronic decerebrate rats. Brain Research 870(1-2): 102-108, 7 July

The chronic supracollicular decerebrate (CD) rat fails to increase meal size in response to systemic/metabolic aspects of food deprivation. Here we asked whether or not deprivation increases immediate oral motor responding to taste stimuli (taste reactivity) in CD rats, as it does in neurologically intact controls. The responses of CD rats were evaluated as functions of glucose concentration and deprivation state, with taste reactivity responses recorded myographically during 15-s intraoral infusions and during 45-s post-infusion periods. Five glucose concentrations (0, 3.2, 6.25, 12.5, 25%) were each presented three times during each test session. The rats were tested when not-deprived (i.e. receiving their full complement of gavage feedings), deprived (23.5 h) of food and water, and deprived of food but not water. The number of oral motor responses emitted increased monotonically with stimulus concentration; during oral infusions the increase was greatest over the lower half of the concentration range, whereas responding increased linearly with concentration in the post-infusion period. This CD response profile resembled that obtained previously with neurologically intact rats tested according to the same protocols. In contrast to results obtained in intact rats, deprivation did not influence the CD's response to glucose at any concentration or for any observation period. Although the caudal brainstem may receive and process information associated with deprivation state, neural interactions between forebrain and brainstem structures appear necessary for the behavioral expression of deprivation effects on meal size or, as we can now conclude, on immediate oral motor responses to taste stimuli.
