Glutamate is the primary molecule that neurons use to communicate with each other.

Previously, scientists have mostly recorded when neurons fire output signals, but now with a new glutamate indicator, they can record the many inputs that causes cells to fire. 🧵

This one involved a lot of sweat and tears, and it was a real tour de force. It was also the last paper we got to write with Jim, so it's a special one (and hence, the tears).

How does a fish know when to blend in? Scientists identified a key circuit controlling camouflage in zebrafish – from cells in the retina sensing light to nerve cells in the brain controlling the release of a hormone that pales the skin to match bright backgrounds.
