Simultaneous monitoring of animal behavior and neuronal activity in the brain enables us to examine the neural underpinnings of behaviors. Conventionally, the neural activity data are buffered, amplified, multiplexed, and then converted from analog to ...

A Bio-Inspired 3-D Neural Compass Based on Head Direction Cells
Head direction cells (HDCs) in mammals’ brains are thought to provide the sense of direction (function of a compass). They fire when the animal’s head points to a specific orientation.

Statistical and information properties of head direction cells [PDF]
The human channel capacity for identifying sensory stimuli is compared with channel capacities based on neurophysiological findings. Studies have shown that cells in the postsubiculum (PoS) and the anterior dorsal thalamus (ADN) of the rat discharge as a function of the animal's head direction in the horizontal plane.

Vision plays an important role in the head direction cell system in animals. Here the authors recorded from head direction cells in rd1 mice that show retinal degeneration at 1 month, and find that they use smell cues to maintain stable HD tuning.

To derive meaningful navigation strategies, animals have to estimate their directional headings in the environment. Accordingly, this function is achieved by the head direction cells that were found in mammalian brains, whose neural activities encode one’

Rapid Spatial Reorientation and Head Direction Cells [PDF]
It is surprising how quickly we can find our bearings when suddenly confronted with a familiar environment, for instance when the lights are turned on in a dark room. Subjectively, this appears to occur almost instantaneously, yet the neural processes permitting this rapid reorientation are unknown.

Head direction maps remain stable despite grid map fragmentation
Areas encoding space in the brain contain both representations of position (place cells and grid cells) and representations of azimuth (head direction cells).
