When I moved to BCM, an extremely talented movement disorders neurologist, Nora Vanegas Arroyave, reached out to discuss brain circuits responsible for non-motor deficits in Parkinson's Disease. I have learned so much from her and from this collaboration. One paper out, more to come!

Out today at Neuron, our experiments show that frontal cortical representation of economic variables is jointly determined by spatial organization and downstream
connectivity of neurons, revealing a structured, multi-scale code for economic variables. www.cell.com/neuron/fullt...

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.

🚨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!)

Change-of-mind neuroeconomic decision-making is modulated by LINC00473 in medial prefrontal cortex in a sex-dependent manner Long non-coding RNA LINC00473 in mPFC alters change-of-mind re-evaluative decision-making behavior related to negative rumination.

This speaks to the importance of cross-species research that is constantly forward- & back-translated between the clinic & lab. The importance of animal models leading to unanticipated discoveries - even in the realm of human psychology - is invaluable, especially in psychiatry🧠 tinyurl.com/yur3j2n8

+ evidence that sensitivity to sunk costs & change-of-mind regret stem from a shared value function related to negative rumination & stress susceptibility.

Here, we discovered LINC00473 in mPFC specifically altered change-of-mind decisions in female mice only. This was driven by enhanced sensitivity to sunk costs and how much re-evaluating recent mistakes influenced future choices. This is the 1st demo of non-coding RNA playing a role in cognition 5/6

A recent study led by @ornaissler.bsky.social found levels of the non-coding RNA LINC00473 were reduced specifically in mPFC 🧠 of women but not men diagnosed with MDD, based on post-mortem human 🧠 tissue studies. Expressing LINC00473 in mPFC promotes resilience to stress in female mice only. 4/6 🐭

Women are 2x as likely to develop depression than men. Major depressive disorder can manifest w different symptoms b/t sexes, including alterations in negative rumination on the past.
