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 …
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 …
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…
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 …
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 …
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 …
Head direction cells in the mammalian limbic system are thought to function as an allocentric neuronal compass. Although traditional views hold that the compass of ground-dwelling species is planar, Angelaki et al. 2019 show that head-direction cells in the rodent …
NeuroSLAM: Neural Simultaneous Localization and Mapping Workshop
Simultaneous Localization and Mapping (or SLAM) refers to the problem of constructing a map of an unknown environment as it is actively being explored. SLAM has been treated extensively in mobile robotics, providing …
The note is an excerpt from the Shinder et al. 2019. We just describe some key conception and results in this study as a significant note. Please read the original paper if you are interested in the study on https://www.physiology.org/doi/full/10.1152/jn.00880.2017…
The brain’s spatial map is supported by place cells, encoding current location, and grid cells, which report horizontal distance traveled by producing evenly sized and spaced foci of activity (firing fields) that tile the environment surface. Casalia et al. 2019 …
J. Dupeyroux et al. 2019 presents a navigation system inspired by desert ants’ navigation behavior, which requires precise and robust sensory modalities.
They tested several ant-inspired solutions to outdoor homing navigation problems on a legged robot using two optical sensors …
Concept cells in the human hippocampus encode the meaning conveyed by stimuli over their perceptual aspects. Baraduc et al. 2019 investigate whether analogous cells in the macaque can form conceptual schemas of spatial environments.
Each day, monkeys were presented …
Place recognition is a complex process involving idiothetic and allothetic information. In mammals, evidence suggests that visual information stemming from the temporal and parietal cortical areas (‘what’ and ‘where’ information) is merged at the level of the entorhinal cortex (EC) …
A latest report about grid cells from Sainsbury Wellcome Centre at UCL. The following is excerpted from the report.
Our ability to navigate the world, and form episodic memories, relies on an accurate representation of the environment around us. …
