Animals were then prepared for surgery. Surgery and recording Under anesthesia a hole for craniotomy was drilled exposing dura. A bolt was embedded on the skull using dental cement, for head fixation during recording. 1-3 days of recovery were given before the first recording session. Fig 2 shows recorded areas of the cerebellum.
Arrows mark the target regions.
Bottom panel shows possible patterns of temporal coding of CRs by a hypothetical processing unit. All three cells showed changes in firing rate during CRs. CELL 1 and CELL 2 were recorded from nucleus interpositus and CELL 3 was recorded from the cortical area. Bottom panels show the response of single units on single trials. Top traces show eyelid position, and the bottom traces show neuronal activity.
