In the early 1970s, Andersen and colleagues proposed that the principal excitatory pathways
of the hippocampal formation were organized in a lamellar fashion. This proposition, based …

Grid cells in layer II of the medial entorhinal cortex form a principal component of the
mammalian neural representation of space. The firing pattern of a single grid cell has been …

As the interface between hippocampus and neocortex, the entorhinal cortex is likely to play
a pivotal role in memory. To determine how information is represented in this area, we …

Memory encoding occurs rapidly, but the consolidation of memory in the neocortex has long
been held to be a more gradual process. We now report, however, that systems …

The thalamic midline and intralaminar nuclei, long thought to be a non-specific arousing
system in the brain, have been shown to be involved in separate and specific brain functions, …

Grid cells in the medial entorhinal cortex (MEC) are part of an environment-independent spatial
coordinate system. To determine how information about location, direction, and distance …

The precise functional role of the hippocampus remains a topic of much debate. The dominant
view is that the dorsal (or posterior) hippocampus is implicated in memory and spatial …

Tauopathy in the brain of patients with Alzheimer's disease starts in the entorhinal cortex (EC)
and spreads anatomically in a defined pattern. To test whether pathology initiating in the …

Projections of the hippocampal formation to the prefrontal cortex were visualized in the rat
by means of the anterograde tracer Phaseolus vulgaris‐leucoagglutinin. These projections …

As implied by its name, the parahippocampal region (PHR), by some authors also named the
retrohippocampal area, is a brain area that lies adjacent to the hippocampal formation. It is …
