[Motivational dependence of changes in visual evoked potentials in rats during water deprivation].
Visually evoked potentials (VEPs) of the visual cortex, the dorsal geniculate nucleus and the lateral hypothalamus of satiated and water-deprived rats with and without additional drinking sounds to strengthen motivation were recorded. Differences in the motivational state led to changes in VEPs and altered interrelations in space and time between these brain areas, as estimated the method of coincidence analysis of single VEP.
