The robust representation of allocentric direction by head direction cells suggests that they provide a neural compass for the animal. However, evidence linking head direction cells and spatial behavior has been mixed. Whereas damage to the hippocampus yields profound deficits in a range of spatial tasks, lesions to the head direction cell system often yield milder impairments in spatial behavior. In addition, <strong><span style=\"color: #ff0000;\">correlational approaches have shown a correspondence between head direction cells and spatial behavior in some tasks, but not others<\/span><\/strong>. These mixed effects may be explained in part by <strong><span style=\"color: #ff0000;\">a new view of the head direction cell system arising from recent demonstrations of at least two types of head direction cells: \u2018traditional\u2019 cells, and a second class of \u2018sensory\u2019 cells driven by polarising features of an environment<\/span><\/strong>. <strong><span style=\"color: #ff0000;\">The recognition of different kinds of head direction cells may allow a nuanced assessment of this system\u2019s role in guiding navigation.<\/span><\/strong>&#8220;<\/p>\n<p style=\"text-align: justify;\">Dudchenko, Paul A., Emma R.
