Microdialysis was performed in the cerebellar cortex on aged rats during training in the delay eyelid conditioning task. The time window of GABA release once eyelid conditioning starts can be observed on day 1 (A; N= 5 condition, 4 pseudocondition), day 3 (B; N= 5 condition, 4 pseudocondition) and day 5 (C; N= 5 condition, 5 pseudocondition). GABA release was significantly greater in the conditioning group on day 1 compared to day 5 (p<0.05). The pattern of release in aged rats changes across days so that by day 5 GABA remains elevated 2 hours after training. Data are expressed as percent of baseline (% baseline) (y-axis). Black squares represent conditioning, open squares represent pseudoconditioning. (D) Area under the curve representation of GABA release for each day of training during eyeblink conditioning
