In keeping with the historical focus of this special issue of Hippocampus, this paper reviews
the history of my development of the SPEAR model. The SPEAR model proposes that …

The discovery of place cells and head direction cells in the hippocampal formation of freely
foraging rodents has led to an emphasis of its role in encoding allocentric spatial …

A commentary is provided on issues raised in the Special Issue of Hippocampus (2023) on
hippocampal system view representations. First, the evidence for hippocampal and …

Complex sensory information arrives in the brain from an animal's first-person ('egocentric')
perspective. However, animals can efficiently navigate as if referencing map-like …

Cells selectively activated by a particular view of an environment have been found in the
primate hippocampus (HPC). Whether view cells are present in other brain areas, and how …

How do rodents' and primates' differences in visual perception impact the way the brain
constructs egocentric and allocentric reference frames to represent stimuli in space …

Encoding an event in memory requires neural activity to represent multiple dimensions of
behavioral experience in space and time. Recent experiments have explored the influence …

Visual information is initially represented in retinotopic coordinates and later in craniotopic
coordinates. Psychophysical evidence suggests that visual information is further …

Hippocampal place cells fire in sequences that span spatial environments and non-spatial
modalities, suggesting that hippocampal activity can anchor to the most behaviorally salient …

Neurons in the rat postrhinal cortex (POR) respond to the egocentric (observer‐centered)
bearing and distance of the boundaries, or geometric center, of an enclosed space …
