A new approach to location of the dentate gyrus and perforant path in rats/mice by landmarks on the skull

The hippocampus has important roles in the con-solidation of information from short-term to long-term memory and spatial navigation. Long-term potentia-tion (LTP) has been promoted as a putative neural mechanism of associative memory formation or stor-age in the mammalian brain. LTP was first described by Bliss and Lomo (1973) in the rabbit, in which a stimulation electrode was positioned within the per-forant path (PP) and a recording field electrode in the dentate area of the hippocampus. Although LTP has been used in many brain areas, most have been focused on the hippocampus.
