Data Highlight: Proulx Lab

This data highlight features experiments from Christophe Proulx’s laboratory at the CERVO Brain Research Center of Universit√© Laval.

A) Scheme of the experimental configuration. Fibers were implanted in three brain regions (X, Y, and Z) to allow recording at axon terminals projecting from a distinct GCaMP-expressing region (HUB).

B) Signals were recorded simultaneously at axon terminals in regions X, Y, and Z while mice were allowed to explore an open field. Highlighted bars indicate periods of increased mobility. A coherent “escape” signal can be observed broadcasting from the Hub to all three of these distant brain regions.
