WebFeb 1, 2024 · Head direction (HD) cells fire as a function of the animal's directional heading and provide the animal with a sense of direction. In rodents, these neurons are located primarily within the limbic system, but small populations of HD cells are found in two extralimbic areas: the medial precentral cortex (PrCM) and dorsal striatum (DS). WebFeb 3, 2015 · Head direction (HD) cells are neurons found in the hippocampal formation and connected areas that fire as a function of an animal's directional orientation relative …
WebThe head-direction (HD) system functions as a compass, with member neurons robustly increasing their firing rates when the animal’s head points in a specific direction. HD neurons may be driven by peripheral sensors or, as computational models . postulate, internally generated (attractor) mechanisms. We addressed the contributions of stimulus ... WebMar 25, 2024 · The head direction (HD) system signals HD in an allocentric frame of reference. The system is able to update firing based on internally derived information about self-motion, a process known as path integration. Of particular interest is how path integration might maintain concordance between true HD and internally represented HD. …
WebJun 20, 2024 · The head direction (HD) system partakes in PI by performing one of the computations required: estimating the current HD by integrating angular velocities; namely angular integration. Furthermore, head direction cells in rodents and flies provide an internal representation of orientation that can persist in darkness ( Ranck, 1984 ; … WebThe head-direction (HD) system functions as a compass, with member neurons robustly increasing their firing rates when the animal's head points in a specific direction.

WebDec 23, 2013 · Using the head direction (HD) system as a model, we explored the resolution of conflicts between landmarks and background cues. Sensory cue integration models predict averaging of the two cues, whereas attractor models predict capture of the signal by the dominant cue. We found that a visual landmark mostly captured the HD …
