  • Abstract A series of experiments in rats and rabbits indicates that the hip;ocampus receives two nonspecific inputs from the brain stem, each capable of producing rhythmical slow activity (theta rhythm). One type of theta rhythm can be abolished by injections of atropine sulfate (5 mg/kg, iv, or 25–50 mg/kg, ip) but not by atropine methyl nitrate. Such theta activity typically has a frequency of 4 7 Hz and occurs during ether or urethane anesthesia as well as during behavioral immobility in the… CONTINUE READING
