WebOct 21, 2011 · Head direction cell firing occurs in relation to the animal’s head direction, and not its body position or orientation of its head relative to its body. Head direction cells discharge whether the animal is moving or still, and is primarily independent of the animal’s on-going behavior. Each cell has only one direction in which it fires maximally.

WebPlace-cell firing patterns are often determined by stimuli in the environment such as visual landmarks, and olfactory and vestibular stimuli. Place cells have the ability to suddenly change their firing pattern from one pattern to another, … WebNov 25, 1997 · Firing rates of individual cells are therefore ambiguous descriptions of features and can only be interpreted by comparison across responses of different neurons. This implies the existence of distributed representations. In the presence of multiple independent stimuli, these representations have to be distinguished.

WebOct 1, 2004 · Thus, aperiodic firing cells get across bifurcation points more easily than periodic firing cells do under a small perturbation of g p. In other words, aperiodic firing cells exhibit a significant change more easily than periodic firing cells when subjected to a small perturbation of g p. Therefore, various bifurcations remain still one of ... WebHippocampal place cells exhibit spatially modulated firing, or place fields, which can remap to encode changes in the environment or other variables. Unique among hippocampal subregions, the dentate gyrus (DG) has two excitatory populations of place cells, granule cells and mossy cells, which are among the least and most active spatially ...
