Hi! I’m interested in how mice build and update maps for navigation, focusing on hippocampal circuits and the role of self-motion signals. I use in vivo imaging (SLAP2) in head-fixed treadmill setups, and I also run freely moving experiments to link circuit dynamics to real-world behavior!

Tolman's Sunburst Maze 80 Years on: A Meta‐Analysis Reveals Poor Replicability and Little Evidence for Shortcutting In 1946, Tolman et al. reported that rats could take a novel shortcut to a goal after training on an indirect route, supporting the Cognitive Map theory. However, a review of subsequent Sunburst maze...

Can humans & animals really use internal maps to take shortcuts?

Tolman famously said yes - based largely on his Sunburst maze.

Our new review & meta-analysis suggests evidence is far weaker than you might think.
