  ABSTRACT: Lesions and temporary inactivation of the hippocampus (HPC) in rodents occasionally lead to discrepant amnesic effects. We directly compared and contrasted the retrograde amnesic effects that small HPC lesions (~50% damage), large HPC lesions (~80% damage), and combined dorsal and ventral HPC inactivation using the sodium channel blocker tetrodotoxin (TTX) had on contextual fear conditioning. Compared to control rats, large HPC lesions significantly reduced freezing during retention testing, a behaviour consistent with retrograde amnesia. In contrast, neither the small lesions nor the TTX inactivation significantly reduced freezing. The extent of damage was significantly and negatively correlated with retention performance (r(9) = -0.896, p
