Spatial Navigation In The Brain: A Question Of Scale

Just like our ancestors before us, humans must be able to navigate within both familiar and new environments, whether this involves driving to work or finding our way around a new city. Successful spatial navigation depends on many cognitive processes including memory, attention, and our perception of direction and distance[1]. A key issue, however, is […]

Pyramidal Cell Subclasses Differ By Electrophysiology And Connectivity

Efforts to parse the cellular, molecular, and behavioral components of spatial recognition are paying off with new insight into the neuroscience of memory-guided navigation. At the Janelia Research Campus, postdoctoral research scientist Mark Cembrowski, who is part of Group Leader Nelson Spruston‘s lab, has as his primary research target the subiculum. This is a sub-region […]

How Language Comprehension Is Influenced By Spatial Navigation

The relations between the systems responsible for spatial navigation and language have been examined in a new study from cognitive neuroscientists at the Higher School of Economics and Aarhus University. Language is a complicated cognitive function, which is performed not only by local brain modules, but by a distributed network of cortical generators. Physical experience […]

The Hippocampal–entorhinal Cortex Maps Abstract Relational Knowledge

To help us navigate, the brain encodes information about the positions of landmarks in space in a series of maps. These maps are housed by two neighbouring brain regions called the hippocampus and entorhinal cortex. These regions also encode information about non-spatial relationships, for example, between two events that often occur close together in time. […]

Do Mental Map Neurons Play A Wider Cognitive Role?

The brain area that makes mental maps of your environment plays a much broader role in memory and learning than was previously thought, new research from researchers at Princeton University suggests. The study investigated the hippocampus, a brain region that has been known since the 1970s to become active when rats travel around their environments. […]
