Ipsilateral and contralateral hippocampal CA3–CA1 and CA2–CA1 projections were investigated in adult male Long–Evans rats by retrograde tracing. Injection of the retrograde tracer cholera toxin subunit B in the strata oriens and radiatum of dorsal CA1 resulted in labeling of predominantly pyramidal cells in ipsilateral and contralateral CA3 and CA2.
