Interactions of rabbit neocortical neurons during natural food motivation.
Studies were carried out on the interaction between neurons in the visual and sensorimotor, and in the visual and frontal regions of the neocortex of both hemispheres in sated and starved rabbits. In starved rabbits, there was an increase in number of pairs of neurons with correlated activity, along with an increase in the number of pairs of neurons with frequency interactions in the theta range and a reduction in the number of pairs with interactions in the alpha range; interhemisphere asymmetry occurred in the interaction of neurons in the visual and sensorimotor regions. The greatest increase in the number of pairs of neurons with correlating activity was seen in the left hemisphere, and a preferential sequence of neuron firing appeared.
