* From the Department (Received for of Physiobgy, publiion University January of Chicago 3, 1939) IT IS NOW ESTABLISHED that central neurones may exhibit spontaneous rhythmic . Even when synaptic transmission is blocked these spontaneous waves contue may crease amplitude (Libet Gerard, 1938). We have studied the some of the physical chemical factors that fluence this âtrsicâ periodicity, as well as the effect on it of external stimulation under varyg physico-chemical conditions; certa neural factors affectg the rhythm have also been vestigated. METHOD The left hemisphere of s was widely exposed under light nembutal anaesthesia (35 mg. per kg. traperitoneally), the Horsley-Clarke strument attached. An hour later a concentric needle was placed the desired position along the optic pathways amplified recorded with a crystograph or hode ray oscillograph. Retal stimulation was caused usually by a flash-light directed to the contralateral eye, or sometimes by a sgle flash of a condenser discharge through a 2.5 V. bulb. A polarizg current (less than 1.0 mA.) was passed through tissue between an different silver plate (2 to 3 cm. surface) applied to the surface of the opposite cerebral cortex, a silver wire (2 to 3 mm. unsulated tip) placed 3 to
