Exploring Developmental Change in Ego-Motion Experience Across Infancy
… and intuitively use vision to plan and guide navigation through the local environment. How does this ability develop in infancy? One possibility is that the development of visual representations for navigation is driven by passive exposure to the visual statistics of scenes. Another …

Active Simultaneous Localization and Mapping in Perceptually Aliased Underwater Environments
… or object-based, SLAM. Finally, the technique of actively choosing trajectories that can take into account data association ambiguities between semantic landmarks is still an open research area. This work comprises of two main contributions: the design and implementation of a Gaussian mixture …

Alternating Sequences of Future and Past Behavior Encoded Within Hippocampal Theta Oscillations
… storage of sequential information during spatial navigation of animals. Pyramidal neurons in the hippocampus have been found to intuitively encode locations in space, and are thus termed "place cells". During active exploration, place cells display "phase precession" relative to the ongoing 4-12 …

Lost in trauma: post-traumatic stress disorder, spatial processing and the brain derived neutrophic factor gene.
… the impact of PTSD and of any trauma exposure on navigation performance using a static perspective taking task and a more ‘active’ navigation paradigm. The study also introduced navigation questionnaires to these assessments, to see how accurate individuals with different experiences of trauma …

Human Visual Navigation: Effects of Visual Context, Navigation Mode, and Gender
… authentic virtual environments. Real-world navigational experience was further simulated, through the inclusion of a large roundabout on the route. Three semi-surrounding screens provided a wide field of view. Participants were able to perform the task, but directional estimates showed …
