How the brain implements recognition of familiar faces, objects, and scenes at the neural level?
Bicanski and Burgess 2019 propose that grid cells support visual recognition memory, by encoding translation vectors between salient stimulus features. They provide an explicit neural mechanism for the role of directed saccades in hypothesis-driven, constructive perception and recognition, and …
Whether hippocampal spatial coding principles also provide a universal metric for the organization of non-spatial information?
The latest investigation by Theves et al. 2019 revealed the hippocampus encodes distances in multidimensional feature space.
Highlights
• The hippocampus encodes distances in multidimensional feature space
• Converging evidence from multivoxel pattern and fMRI adaptation analyses
• Results suggest …
How Animals Find Their Way
A new book ‘Supernavigators: Exploring the Wonders of How Animals Find Their Way’ by David Barrie was published in May 28, 2019.
In Supernavigators, award-winning author David Barrie takes us on a tour of the cutting-edge science of animal navigation…
Key brain region for navigating familiar places identified
UCL scientists have discovered the key brain region for navigating well-known places, helping explain why brain damage seen in early stages of Alzheimer’s disease can cause such severe disorientation.
Recent research indicates the hippocampus may code the distance to the …
Whether and how vectorial operations are implemented in the wider neural representation of space?
In environments that contain discrete objects, animals are known to store information about distance and direction to those objects and to use this vector information to guide navigation. Theoretical studies have proposed that such vector operations are supported by …
Insect-Inspired Robots Don’t Need GPS For Orientation
The ‘Brains on Board’ project is a collaboration between several British universities in partnership with the Human Brain Project and seeks to ‘translate’ the brains of ants and bees into algorithms that a machine will understand. Its aim is …
