Allocentric directional processing in the rodent and human retrosplenial cortex
Knight, Rebecca; Hayman, Robin (2014)Head direction (HD) cells in the rodent brain have been investigated for a number of years, providing us with a detailed understanding of how the rodent brain codes for allocentric direction. Allocentric direction refers ... -
Geometric cues influence head direction cells only weakly in nondisoriented rats
Knight, Rebecca; Hayman, Robin; Ginzberg, Lin Lin; Jeffery, Kathryn (2011-11-02)The influential hypothesis that environmental geometry is critical for spatial orientation has been extensively tested behaviorally, and yet findings have been conflicting. Head direction (HD) cells, the neural correlate ... -
Head direction cells are influenced more by visual landmarks than the geometric features of an environment
Knight, Rebecca; Hayman, Robin; Ginzberg, Lin Lin; Jeffery, Kathryn (2010) -
Hippocampal and prefrontal processing of network topology to simulate the future.
Javadi, A; Emo, B; Howard, L; Zisch, F; Yu, Y; Knight, Rebecca; Pinelo, J; Spiers, H (2017-03-21)Topological networks lie at the heart of our cities and social milieu. However, it remains unclear how and when the brain processes topological structures to guide future behaviour during everyday life. Using fMRI in humans ... -
The hippocampus and entorhinal cortex encode the path and euclidean distances to goals during navigation
Howard, Lorelei; Javadi, Amir; Yu, Yichao; Mill, Ravi; Morrison, Laura; Knight, Rebecca; Loftus, Michelle; Staskute, Laura; Spiers, Hugo (2014-06-16)Background: Despite decades of research on spatial memory, we know surprisingly little about how the brain guides navigation to goals. While some models argue vectors are represented for navigational guidance, other models ... -
Integrative cue conflict resolution in the head direction system
Knight, Rebecca; Marozzi, Elizabeth; Hayman, Robin; Nardini, Marko; Jeffery, Kathryn (2012) -
A theoretical account of cue averaging in the rodent head direction system
Page, Hector J. I.; Walters, Daniel M.; Knight, Rebecca; Piette, Caitlin E.; Jeffery, Kathryn J.; Stringer, Simon M. (2014-02-05)Head direction (HD) cell responses are thought to be derived from a combination of internal (or idiothetic) and external (or allothetic) sources of information. Recent work from the Jeffery laboratory shows that the relative ... -
Wayfinding and path integration deficits detected using a virtual reality mobile app in patients with traumatic brain injury
Seton, Caroline; Coutrot, Antoine; Hornberger, Michael; Spiers, Hugo J.; Knight, Rebecca; Whyatt, Caroline (2023-03-09)The ability to navigate is supported by a wide network of brain areas which are particularly vulnerable to disruption brain injury, including traumatic brain injury (TBI). Wayfinding and the ability to orient back to the ... -
Weighted cue integration in the rodent head direction system
Knight, Rebecca; Piette, Caitlin; Page, Hector; Walters, Daniel; Marozzi, Elizabeth; Nardini, Marko; Stringer, Simon; Jeffery, Kathryn (2014-02-05)How the brain combines information from different sensory modalities and of differing reliability is an important and still-unanswered question. Using the head direction (HD) system as a model, we explored the resolution ...
