New paper on how ketamine impacts the neural circuits that support navigation! Congratulations to Kei Masuda and team (Yanjun Sun and @EmilyAeryJones) for a fantastic study on a very novel topic for the lab! 🧵below! biorxiv.org/content/10.1101/…

Ketamine evoked disruption of entorhinal and hippocampal spatial maps

Ketamine, a rapid-acting anesthetic and acute antidepressant, carries undesirable spatial cognition side effects including out-of-body experiences and spatial memory impairments. The neural substra...

I am very excited to share the main project from my graduate work with @lisa_giocomo that is out in @NatureNeuro today! Hippocampal place cell remapping across environments might simply reflect the animal's best guess of the environment identity. This guess depends on experience.

Remapping of place cells in the CA1 region of the #hippocampus is driven by prior experience and approximates an optimal estimate of the identity of the current context; new from @lisa_giocomo and Mark Plitt go.nature.com/3reOnG2

In Campbell, Attinger et al. (@malcgcamp, Alex Attinger, @SamOcko, @SuryaGanguli), we consider the degree to which cortical regions that support navigation follow unique versus universal behaviorally-relevant coding principles. biorxiv.org/content/10.1101/…

Distinct algorithms for combining landmarks and path integration in medial entorhinal, visual and...

During navigation, animals estimate their position using path integration and landmarks, engaging many brain areas. Whether these areas follow specialized or universal cue integration principles...

Up now on BioRxiv – exceptional work (and our first 2P paper) by Mark Plitt! We show that hippocampal neural representations for environmental contexts can be precisely predicted by knowing an animal’s prior experience. biorxiv.org/content/10.1101/…

Experience dependent contextual codes in the hippocampus

The hippocampus is a medial temporal lobe brain structure that contains circuitry and neural representations capable of supporting declarative memory. Hippocampal place cells fire in one or few...

Grid Cells Encode Both Meaning and Position simonsfoundation.org/2019/04… via @SimonsFdn

Grid Cells Encode Both Meaning and Position

New research shows that grid cells don’t simply encode an animal’s location; they also represent how important that location is to the animal. For example, grid cells that represent spots that are…
