[Correlation of the unit activity of the right and left lateral hypothalamus in food motivation].

Correlation between activities of neurons in the right and left lateral hypothalamus of a rabbit recorded during quiet wakefulness, after 24-h food deprivation, and after satiation was studies by plotting cross- and autocorrelation histograms. A predominant order in correlated bilateral discharges of hypothalamic neurons was revealed in hungry animals: in a significantly greater number of cases (59%) the left-side discharges led the right-side ones with time delays to 200 ms (peaks at 30 and 160 ms). The opposite order of discharges was less common (21%). In the state of hunger, the probability of appearance of theta-range frequencies in correlated neuronal discharges increased (from 11 to 29%).
