New year new work from the lab! We explore whether aggression experience and observation lead to similar changes in future aggression strategy. (They do!) We perform 2-color imaging across the whole social behavior network across time and track changes www.biorxiv.org/content/10.1...
Aggression experience and observation promote shared behavioral and neural changes
The ability to observe the social behavior of others and use observed information to bias future action is a fundamental building block of social cognition. A foundational question is whether social o...

Vibrational fiber photometry: label-free and reporter-free minimally invasive Raman spectroscopy deep in the mouse brain - Nature Methods
Vibrational fiber photometry enables Raman spectroscopy in the mouse brain with low impact, owing to the use of tapered fibers.

Data-driven analysis identifies novel modulation of social behavior in female mice witnessing chronic social defeat stress
Chronic social defeat stress is a widely used depression model in male mice. Several
proposed adaptations extend this model to females with variable, often marginal effects.
We examine if the widely u...

BrainGPT surpasses experts in predicting experimental outcomes... of experiments that have already been done.
👉One risk is that scientists do not pursue studies when their predictions run counter to those of an LLM, thereby missing real breakthroughs

so excited to finally announce this to the world!
what’s a probe that can get anywhere in the brain, without destroying any tissue in the way, wiring up to existing structure to extract and inject information?
sounds like a neuron :)

I had an idea way back in college which I've long thought could be, in many ways, the ultimate BCI technology. What if instead of using electrodes, we used biological neurons embedded in electronics to communicate with the brain?

Does anybody have any good resources for brain clearing - light sheet microscopy that they could share? I'd be really keen to give it a shot in the lab.
Thanks in advance!
