Persistent Neural Activity in Head Direction Cells [PDF]
Cerebral Cortex, 2003 Many neurons throughout the rat limbic system discharge in relation to the animal's directional heading with respect to its environment. These so-called head direction (HD) cells exhibit characteristics of persistent neural activity. This article summarizes where HD cells are found, their major properties, and some of the important experiments that ...

Lesions of the head direction cell system impair direction discrimination. [PDF]
Behavioral Neuroscience, 2019 Previous results suggest that directional information from the head direction cell circuit may inform hippocampal place cell firing when an animal is confronted with visually identical environments. To investigate whether such information might also be essential for spatial behavior, we tested adult, male Lister Hooded rats that had received either ...

Encoding of Head Direction by Hippocampal Place Cells in Bats [PDF]
The Journal of Neuroscience, 2014 Most theories of navigation rely on the concept of a mental map and compass. Hippocampal place cells are neurons thought to be important for representing the mental map; these neurons become active when the animal traverses a specific location in the environment (the “place field”). Head-direction cells are found outside the hippocampus, and encode the

Home, head direction stability and grid cell distortion [PDF]
Journal of Neurophysiology, 2019 Abstract The home is a unique location in the life of humans and animals. Numerous behavioral studies investigating homing indicate that many animals maintain an online representation of the direction of the home, a home vector. Here we placed the rat’s home cage in the arena, while recording neurons in the animal’s parasubiculum and ...

Video data for the cognitive mapping process of NeuroBayesSLAM system
Data in Brief, 2020 Simultaneous localization and mapping (SLAM), which addresses the problem of constructing a spatial map of an unknown environment while simultaneously determining the mobile robot's position relative to this map, is regarded as one of the key ...

Topography of Head Direction Cells in Medial Entorhinal Cortex [PDF]
Current Biology, 2014 Neural circuits in the medial entorhinal cortex (MEC) support translation of the external environment to an internal map of space, with grid and head direction neurons providing metrics for distance and orientation.We show here that head direction cells in MEC are organized topographically.

Place cells, head direction cells, and the learning of landmark stability [PDF]
The Journal of Neuroscience, 1995 Previous studies have shown that hippocampal place fields are controlled by the salient sensory cues in the environment, in that rotation of the cues causes an equal rotation of the place fields. We trained rats to forage for food pellets in a gray cylinder with a single salient directional cue, a white card covering 90 degrees of the cylinder wall ...

Activity dependent feedback inhibition may maintain head direction signals in mouse presubiculum
Nature Communications, 2017 Head direction is encoded by cells in the presubiculum, but the role of local circuitry in head direction encoding remains unknown. Here the authors demonstrate how a specific inhibitory neuron type, the Martinotti cell, together with excitatory ...

Frontiers in Neural Circuits, 2019 Complex spatial representations in the hippocampal formation and related cortical areas require input from the head direction system. However, a recurrent finding is that behavior apparently supported by these spatial representations does not appear to ...
