Spatial information enhanced by non-spatial information in hippocampal granule cells

Do hippocampal pyramidal cells signal non-spatial as well as spatial information?

It is generally agreed that the rat hippocampus is involved in spatial memory. Whether this is its sole or primary function, or merely one component of a broader function, is still debated. It has been suggested, for example, that the hippocampus stores information about flexible relations between stimuli, both spatial and non-spatial. In this paper, I reiterate the basic tenet of the cognitive...

Understanding Spatial and Non- Spatial Cues in Representing Categorical Information

The continuously increasing amount of digital information available to computer users has led to the wide use of notification systems. Although these systems could support the management of information, they could also be an interruption to primary work. To minimize this interruption, a number of approaches, which notify the different categorical information, have been introduced. In this work,...

Supplemental Information Dendritic Integration in Hippocampal Dentate Granule Cells

Spatial information outflow from the hippocampal circuit: distributed spatial coding and phase precession in the subiculum.

Hippocampal place cells convey spatial information through a combination of spatially selective firing and theta phase precession. The way in which this information influences regions like the subiculum that receive input from the hippocampus remains unclear. The subiculum receives direct inputs from area CA1 of the hippocampus and sends divergent output projections to many other parts of the b...

Human hippocampal CA1 involvement during allocentric encoding of spatial information.

A central component of our ability to navigate an environment is the formation of a memory representation that is allocentric and thus independent of our starting point within that environment. Computational models and rodent electrophysiological recordings suggest a critical role for the CA1 subregion of the hippocampus in this type of coding; however, the hippocampal neural basis of spatial l...
