[The effect of stimulation of the lateral hypothalamus on the spike trains of the rabbit neocortical neurons].

[Article in Russian]


Cross- and autocorrelation histograms of the impulse activity of the visual and sensorimotor cortical neurons were plotted before and after stimulation of the right (RH) and left lateral hypothalamus (LH) which provoked food motivation reactions. Reorganization in correlated activity of neocortical neurons was more expressed after the LH than the RH stimulation. Only after the LH stimulation the number of neuronal pairs with co-related activity in the left hemisphere increased by 41% and some order of priority appeared in the neuronal discharges. The visual neurons discharged after the sensorimotor ones with delays up to 120 ms. The conclusion was drawn that cortical interhemispheric asymmetry of electrical activity during hunger was associated with unequal operation of the right and left lateral hypothalamus.
