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...

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...

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.

Exciting news from the lab! In collaboration with our #EU-Nanobrigth partners, we’ve developed and tested a new probe for vibrational fiber photometry, enabling minimally invasive Raman spectroscopy deep into the 🧠. www.nature.com/articles/s41... @naturemethods.bsky.social

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...

Activation of somatostatin neurons in the medial amygdala reverses long-term aggression and social deficits associated to early-life stress in male mice Molecular Psychiatry - Activation of somatostatin neurons in the medial amygdala reverses long-term aggression and social deficits associated to early-life stress in male mice

🚨Exciting news from our lab! Our latest study is published in @molpsychiatry! rdcu.be/d1dZW 🎉Big kudos to the team, specially to @aroamanasojeda.bsky.social , who worked very hard to get this paper out! #NESTLab_UJI #REISestres #fcs_UJI #Stress #MentalHealth #SocialBehavior 👇🧵

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

🚀 New insights into how dopamine & serotonin shape learning! 🧠✨ Malenka group’s shows DA & 5HT in the nucleus accumbens work together to drive associative learning. Manipulating both disrupts & enhances behavior! 🔬

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 :)

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!

It is almost impossible to amass and maintain extreme wealth without some large portion of it being dirty.
