My mother passed away, after a life defined by grace, humility, and courage. Even in her final days, her words to me were the same as always: "Himmat karo" — have courage. She lived it — hardworking, generous to all. As we grieve, we stay inspired by her. Rest in peace, Amma. 🙏

Can a single brain cell decide whether to eat or not? 🧠🪰 Turns out... yes. And we found it in the fruit fly. A pair of neurons called SELKs (subesophageal leucokinin neurons) can drive feeding behavior in both directions. They promote it or suppress it. Here's how: 🧵

*First preprint from our lab* !!!!! How does the brain learn to anchor its internal sense of direction to the outside world? 🧭 led by Mark Plitt @markplitt.bsky.social & Dan Turner-Evans, w/ Vivek Jayaraman: “Octopamine instructs head direction plasticity” www.biorxiv.org/content/10.6... Thread ⬇️
Schematic of how ER-EPG plasticity enables the bump of activity in EPGs to accurately track visual cues. As a fly makes a counter-clockwise turn (top to bottom) it will view visual cues (e.g. the sun) from a new angle and the EPG activity bump (red) will swing clockwise around the network by integrating self motion signals with these visual inputs. When the fly faces a different angle, distinct visual ER neurons are active. Plasticity forms a trough of weak synapses (large circles - strong synapses, small circles - weak synapses) that allow ER neurons with distinct visual tuning to move the EPG bump via disinhibition.
