Abstract: The tetrapeptide tuftsin (Thr-Lys-Pro-Arg) injected intraperitoneally into cats altered the bioelectrical activity of sensory, motor, and limbicoreticular structures in the wakeful state, during two different phases of sleep, and also when the caudate nucleus was electrically stimulated. In wakefulness and during REM sleep, absolute values of the electroencephalographic power spectrum were increased in all the brain structures under study, while during slow-wave sleep they were increased in the sensorimotor cortical areas and decreased in the central medial thalamic nuclei and hippocampus. Tuftsin facilitated the genesis of slow waves in subcortical structures and the expression of theta waves in the hippocampus. It also increased the amplitude of evoked potentials and elongated spindles when the caudate nucleus was stimulated. |
