Couldn’t be more excited to see this work out!! Not just manipulating PV+ cell theta phase, but also shifting seizure susceptibility! how much cooler can it get?!!!
🚨New preprint alert🚨
We used closed-loop optogenetics to causally test the importance of inhibitory spike timing in network function and found that manipulating PV+ cell theta phase locking in the dentate gyrus can shift seizure susceptibility (both ways!)

Check out new work from our lab! We developed a new way to directly control the precise timing of interneurons during behavior and found that theta phase locking is a causal mediator of seizure susceptibility in both healthy and epileptic mice.

Super excited to share the first cooperative foraging paradigm in freely interacting mouse pairs! Stable leader and follower roles emerge spontaneously and predict learning. Well-trained mice show stereotyped, role-specific “behavioral motifs” absent in naive animals (1/5)
