Adult female garden spider (Araneus diadematus) sitting at the center of her orb web, with orange‑brown legs and a patterned abdomen. The web’s radial and spiral threads are sharply visible, catching the light. The background is blurred green foliage with soft circular highlights, making the spider and web stand out in clear focus.

Almost ten years ago, we first proposed VPM4 might facilitate exploration-exploitation by inhibiting MBON-11. Finding it was indeed inhibitory was a highlight. Now, Prunier et al. reveal the synaptic mechanism and VPM4 also drives aggression. Beautiful example of neuronal multiplexing in insects.

*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.
