La investigación de mi alumna @aleloc.bsky.social y del laboratorio: www.jornada.com.mx/noticia/2025...

Científicos de UNAM usan estimulación magnética transcraneal contra las adicciones

A través de una bobina que se coloca sobre el cuero cabelludo se generan campos magnéticos que incentivan regiones cerebrales.

When I first started working with resting state fMRI as a postdoc, there was a lot of skepticism about what we could learn from it. 20 years later, it's hard to imagine where the field of neuroscience would be without it. Here's a summary 🧠 www.nature.com/articles/s41...

We found a more strongly connected network in recurrent MDD when combining symptoms and brain characteristics. We also found that insomnia and somatic symptoms seem to be central to recurrent MDD, suggesting these symptoms could serve as possible clinical targets.

Awesome @afni-pt.bsky.social invited me to this and I think it's a great concept.

Paul Taylor @afni-pt.bsky.social · Apr 11

The result of a large (42 authors!) collaboration:
"Go Figure: Transparency in neuroscience images preserves context and clarifies interpretation"
arxiv.org/abs/2504.07824
TL;DR: The FMRI world can (and should) improve results interpretation and reproducibility *today*, via transparent thresholding.

7 years ago, I received funding for a project on personality, incentivized prosocial behavior & social status in groups. Today, we've made the anonymized data publicly available. Researchers can now use it by citing the preprint/paper (no need to add anyone as a coauthor): doi.org/10.31234/osf...

In the Group Interaction and Perception of Others (GIPO) project, we collected data (N = 1,460) containing a large number of self- and informant-reported personality items and incentivized measures of prosocial and cheating behavior. Many participants (N = 699) also attended a laboratory session in which they interacted in groups of 7-9 individuals in two modified versions of the public goods game with punishment. During and after the public goods games, participants reported their perceptions, expectations, and evaluations of each other through round-robin ratings. Due to the extensive assessments of personality and incentivized social behavior included in the GIPO data, these data are suitable for investigating the links between personality traits and prosocial and cheating behavior. Furthermore, they can be analyzed to gain a fine-grained picture of the perceptions, expectations, and evaluations that precede or follow behavior in economic games. Finally, researchers might want to use the GIPO data to investigate the psychometric properties and in particular the validity of the personality measures we used. To facilitate use of the data, we made the anonymized GIPO data publicly available. Taken together, the GIPO data are a publicly available rich resource for investigating the links between personality and incentivized social behavior.
Keywords: personality assessment, game theory, social dilemmas, social status, influence, likeability, trust, group dynamics

We also found higher microglia count and region-specific phenotypes. More info in the preprint.

Using deformation-based morphometry, we found that morphine self-administration was related to volume changes in regions like cerebellum, basal ganglia and insula, among others.

Eduardo Garza-Villarreal @egarza.bsky.social · Feb 26

For this we measured in vivo structural MRI before and after morphine self-administration using FR-1 in adolescent rats. Then, we did microscopy analysis of microglia cell count and phenotype using immunofluorescence.

New preprint from the lab: www.biorxiv.org/content/10.1...
This was led by former Bachelor student Débora Elizarrarás and postdoc César Carranza. Here we wanted to study structural brain changes in opiod self-administration. Specifically if there was a link between MRI volume and neuroinflamation.

Morphine self-administration induces region-specific brain volume changes and microglial phenotypic alterations without affecting neuronal density in male Wistar rats

Addiction to opioids, including morphine, is a major public health crisis in the U.S. It has been associated with brain volume changes in reward-related regions, neuronal death, and neuroinflammation....

We found that chronic stress did not increase ethanol drinking. We also found that chronic stress and ethanol intake distinctly and in combination affected several networks in development, where males were more affected in brain structure and females in functional connectivity:

Eduardo Garza-Villarreal @egarza.bsky.social · Feb 14

To answer this we used an animal model with chronic physical stress + ethanol drinking and did longitudinal ethanol intake and neuroimaging measures, as well as multivariate analysis.
