Multiunit activity in the mesencephalic reticular formation and septal area of freely moving newborn rat.
A surgical technique to implant stereotaxically fixed probes for recording multiunit activity /MUA/ from the mesencephalic reticular formation and septal area of freely moving 6--12 hr old newborn rat is described. In both brain areas the spontaneous firing of neuron populations showed close correlation with the stages of wakefulness and sleep cycle.
