Abstract
The distribution of hippocampal mossy fiber terminals, visualized by means of Timm''s Ag2S stain, was determined morphometrically in a selected hippocampal region. Five inbred mouse strains and 2 rat strains were used, all of them characterized by genetically controlled differences in performing a 2-way avoidance task (shuttle-box). Those rat and mouse strains known for low avoidance scores had significantly more mossy fiber terminals synapsing within or below the layer of hippocampal pyramidal neurons.
