DOI: 10.1002/hipo.22680
Abstract: The rodent postrhinal cortex (POR), homologous to primate areas TH/TF and the human 'parahippocampal place area', has been implicated in processing visual landmark and contextual information about the environment. Head direction (HD) cells are neurons… read more here.

DOI: 10.1016/j.bbr.2017.10.026
Abstract: &NA; The lateral mammillary nuclei are a central structure within the head direction system yet there is still relatively little known about how these nuclei contribute to spatial performance. In the present study, rats with… read more here.

DOI: 10.1016/j.cub.2021.04.071
Abstract: Birds are experts in many behaviors akin to those in mammals that are known to involve the hippocampus, yet the avian hippocampus is still poorly understood. A new study finds head-direction cells, but not place… read more here.

DOI: 10.1098/rstb.2021.0452
Abstract: The neural coding of space centres on three foundational cell types: place cells, head direction cells and grid cells. One notable characteristic of these neurons is the symmetry properties of their spatial firing patterns. In… read more here.

DOI: 10.1152/jn.00518.2019
Abstract: The home is a unique location in the life of humans and animals. In rats, home presents itself as a multicompartmental space that involves integrating navigation through subspaces. Here we embedded the laboratory rat’s home… read more here.

DOI: 10.3389/fnbot.2022.867019
Abstract: Maintaining a stable estimate of head direction requires both self motion (ideothetic) information and environmental (allothetic) anchoring. In unfamiliar or dark environments ideothetic drive can maintain a rough estimate of heading but is subject to… read more here.

Sign Up to like & getrecommendations! Published in 2020 at "eLife"
DOI: 10.7554/elife.53985
Abstract: Recent studies of the Central Complex in the brain of the fruit fly have identified neurons with activity that tracks the animal’s heading direction. These neurons are part of a neuronal circuit with dynamics resembling… read more here.
