Below is a massive list of head direction cells words - that is words related to head direction cells.

Example of head direction cells. English is considered to be strongly head-initial while Japanese is an example of a language that is consistently head-final. Head direction may refer to. The two most important modules are H a one-dimensional cyclic attractor map CANN encoding the head direction of an agent containing HD cells arranged on a circle in the order of their head-direction preference and a P a two-dimensional attractor map used to encode the agents current position as well as for path integration containing place cells arranged in a plane with weights that decrease with distance.

A HD cell has a unique preferred di-rection for which it discharges maximally. One of the most interesting aspects of head direction cells is that their firing is not fully determined by sensory features of the environment. These neurons fire at a steady rate ie.

Adapted with permission from Wiener et al. To test this one approach has been to correlate changes in head direction cells with changes in behavior Dudchenko. Head-direction tuning of hippocampal place cells in rodents as reported in previous studies of rat CA1 neurons.

The head direction cells were the second class of spatially responsive neuron to be discovered in rodents place cells were the first but we describe head direction cells first here because the sense of direction is both simpler and more fundamental and the insights derived from this system have been informative for understanding the sense of place too. The directional coding of the HD cells is independent of the animal location and provides therefore an allocentric directional representa-tion. By understanding the purpose and interaction of these brain areas a model of the system can be built.

Over the first few minutes of exploration the animal learns to. The head is the element that determines the category of a phrase. These include the anterior dorsal division is passively rotated in the experimenters hand through the of the anterior thalamic nuclei ADN 3 the dorsal preferred direction.

Head Direction cells were first discovered in an area of the brain known as the Post-Subiculum PSc but cells that fire as a function of the rats heading have since been discovered in other brain areas.
