Theta-modulated place-by-direction cells in the hippocampal formation in the rat [PDF]
, 2004 We report the spatial and temporal properties of a class of cells termed theta-modulated place-by-direction (TPD) cells recorded from the presubicular and parasubicular cortices of the rat. The firing characteristics of TPD cells in open-field enclosures

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 ...

Segregation of cortical head direction cell assemblies on alternating theta cycles [PDF]
, 2013 High-level cortical systems for spatial navigation, including entorhinal grid cells, critically depend on input from the head direction system. We examined spiking rhythms and modes of synchrony between neurons participating in head direction networks ...

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 ...

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 ...

Linear Self-Motion Cues Support the Spatial Distribution and Stability of Hippocampal Place Cells [PDF]
, 2018 The vestibular system provides a crucial component of place-cell and head-direction cell activity [1-7]. Otolith signals are necessary for head-direction signal stability and associated behavior [8, 9], and the head-direction signal's contribution to ...

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

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 ...

Environmental Anchoring of Head Direction in a Computational Model of Retrosplenial Cortex [PDF]
, 2016 Allocentric (world-centered) spatial codes driven by path integration accumulate error unless reset by environmental sensory inputs that are necessarily egocentric (body-centered).

An implementation of the path integrator mechanism of head direction cells for bio-mimetic navigation [PDF]
, 2014 © 2014 IEEE. Head direction cells are thought to be an integral part of the neural navigation system. These cells track the agent's current head direction irrespective of the host's location.
