Using Grid Cells for Navigation
Mammals are able to navigate to hidden goal locations by direct routes that may traverse previously unvisited terrain. Empirical evidence suggests that this "vector navigation" relies on an internal representation of space provided by the hippocampal formation. The periodic spatial firing patterns of grid cells in the hippocampal formation offer a compact combinatorial code for location within ...
متن کاملSpatial Cognition: Grid Cells Support Imagined Navigation
Grid cells in the entorhinal cortex represent an animal's current location during navigation. A new study indicates that grid cells in humans also represent information about imagined movement and spatial orienting, suggesting that the entorhinal network has a flexible role in spatial representation.
متن کاملSpeech-Based Navigation: Improving Grid-Based Solutions
Speech-based technology is a useful alternative to traditional input techniques such as the keyboard and mouse. For people with disabilities that hinder use of traditional input devices, a hands-free speech-based interaction solution is highly desirable. Various speech-based navigation techniques have been discussed in the literature and employed in commercial software applications. Among them,...
متن کاملGrid-like Processing of Imagined Navigation
Grid cells in the entorhinal cortex (EC) of rodents [1] and humans [2] fire in a hexagonally distributed spatially periodic manner. In concert with other spatial cells in the medial temporal lobe (MTL) [3-6], they provide a representation of our location within an environment [7, 8] and are specifically thought to allow the represented location to be updated by self-motion [9]. Grid-like signal...
متن کاملGrid-Based Navigation for Autonomous, Mobile Robots
Navigation is a major challenge for autonomous, mobile robots. The problem can basically be divided into positioning and path planning. In this paper we present an approach which we call grid-based navigation. Though we also propose a scheme for path finding, we focus on positioning. Our approach uses minimal environmental infrastructure and only two light sensors on the mobile device itself. S...
