Transformation of a Spatial Map across the Hippocampal-Lateral Septal Circuit

Transformation of a Spatial Map across the Hippocampal-Lateral Septal Circuit

The hippocampus constructs a map of the environment. How this “cognitive map” is utilized by other brain regions to guide behavior remains unexplored. To examine how neuronal firing patterns in the hippocampus are transmitted and transformed, we recorded neurons in its principal subcortical target, the lateral septum (LS). We observed that LS neurons carry reliable spatial information in the phase of action potentials, relative to hippocampal theta oscillations, while the firing rates of LS neurons remained uninformative.

BrainSTEM (Brain STructured Experimental Metadata) is a collaborative electronic lab notebook for FAIR experimental neuroscience. It has a customizable web interface and a standardized yet flexible data model and is designed to capture a range of electrophysiology, imaging, and behavioral data. Granular permissions, including one-click public sharing, promote collaborations and open science. BrainSTEM is designed with ease of adoption and use as a primary consideration and facilitates compliance with NIH and other data-sharing requirements.

BrainSTEM can accelerate your science, promote collaboration, extend the lifetime of your data, and make FAIR data sharing easy. Please see the dedicated documentation website at below link.
