[Neuromediator sensitivity of neurons of the reticular formation and orbital cortex in hungry and satiated rabbits].
In conditions of stereotaxic fixation, noradrenaline microionophoresis and stimulation of the lateral hypothalamus acted in the same sense on impulse activity of 35 and 37% of the neurones in the reticular formation of satiated rabbits, in joint action increasing the number of cells with distribution of intervals characteristic of alimentary motivational excitation. Microionophoresis of acetylcholine to the neurones of the orbital cortex in freely behaving rabbits reshaped the impulse activity of 57% of cells in accordance with the pattern of discharge activity characteristic of alimentary motivational excitation. Such excitation, natural as well as artificially evoked, widens polychemical properties of the neurones of the reticular formation and, on the contrary, narrows polychemical properties of the nerve cells of the orbital cortex.
