this study was designed to determine ( 1 ) which brain area paces the theta rhythm in the medial entorhinal cortex ( mec ) of rats and ( 2 ) the extent to which the behavioral effects of lesions in the medial septal area ( msa ) , which disrupt the cholinesterase-related pathway to the hippocampal formation , resemble the effects previously reported to result from fimbria-fornix lesions .
