The Neural Correlates of Spatial Disorientation in Head Direction Cells
eneuro, 2022 While the brain has evolved robust mechanisms to counter spatial disorientation, their neural underpinnings remain unknown. To explore these underpinnings, we monitored the activity of anterodorsal thalamic head direction (HD) cells in rats while they underwent unidirectional or bidirectional rotation at different speeds and under different conditions (

During hippocampal inactivation, grid cells maintain synchrony, even when the grid pattern is lost
eLife, 2019 The grid cell network in the medial entorhinal cortex (MEC) has been subject to thorough testing and analysis, and many theories for their formation have been suggested.

Angular and linear speed cells in the parahippocampal circuits
Nature Communications, 2022 It remains unclear how the hippocampal region integrates position and self-motion information to update spatial representations. Here, the authors report grid and head direction cells as well as cells encoding self-motion parameters such as angular head ...

Path integration of head direction: updating a packet of neural activity at the correct speed using axonal conduction delays. [PDF]
PLoS ONE, 2013 The head direction cell system is capable of accurately updating its current representation of head direction in the absence of visual input. This is known as the path integration of head direction.

Three-dimensional tuning of head direction cells in rats [PDF]
Journal of Neurophysiology, 2019 Head direction (HD) cells fire when the animal faces that cell’s preferred firing direction (PFD) in the horizontal plane. The PFD response when the animal is oriented outside the earth-horizontal plane could result from cells representing direction in the plane of locomotion or as a three-dimensional (3D), global-referenced direction anchored to ...

The vestibular contribution to the head direction cells signal and navigation
Frontiers in Integrative Neuroscience, 2014 Spatial learning and navigation depend on neural representations of location and direction within the environment. These representations, encoded by place cells and head direction cells, respectively, are dominantly controlled by visual cues, but ...

How the cerebellum may monitor sensory information for spatial representation
Frontiers in Systems Neuroscience, 2014 The cerebellum has already been shown to participate in the navigation function. We propose here that this structure is involved in maintaining a sense of direction and location during self-motion by monitoring sensory information and interacting with ...

Frontiers in Behavioral Neuroscience, 2018 According to the currently prevailing theory, hippocampal formation constructs and maintains cognitive spatial maps. Most of the experimental evidence for this theory comes from the studies on navigation in laboratory rats and mice, typically male ...

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Therapeutic apheresis (TA) is an established treatment modality for hematologic, neurologic, and immunologic disorders, yet access remains severely limited in sub‐Saharan Africa. Donor apheresis, including platelet apheresis collection from healthy donors, represents an important complementary modality supporting blood product ...
