[EEG-correlates of alimentary behavior in rabbits with different levels of hunger and satiety]. / EEG-korreliaty pishchevogo povedeniia u krolikov pri razlichnykh urovniakh goloda i nasyshcheniia

The electrical activity of the rabbit brain at different stages of hunger and satiation was correlated with the animal's behavioral reactions. It has been found that alimentary reactions are attended with the appearance of complex high-amplitude and high-frequency electrical potentials in the lateral hypothalamic area, which increased with the longer duration of the animal's hunger, as well as during search, in response to natural and conditioned alimentary stimuli, and when feeding. As satiation sets in, they fade and disappear after food refusal. It is assumed that this form of activity is an EEG expression of alimentary motivational excitation. Its constituent rhythms reflect the different components of alimentary excitation.
