For those in the San Diego area interested in donating physical goods for earthquake victims in Venezuela, Encuentro cafe is collecting donations today (3941 Mason St, San Diego, CA 92110). Most needed are first aid supplies, hygiene products, diapers, electrolyte liquids and non-perishable food.

Posting for Vibhu Sahni: Due to unforeseen circumstances the Burke Neurological Institute will have to terminate its research operations 5/22. There are international postdocs on visas who are looking for new homes. Please reach out to Vibhu if you can help

Mammals have hundreds of joints and muscles. Controlling them individually would be nearly impossible. How does the nervous system organize such complexity into coherent actions? Our new study explores this question through a natural behavior: jumping.

The Buck Institute for Research on Aging invites applications for a faculty position honoring the scientific legacy of Dr. Judith Campisi, a pioneer in the field of cellular senescence and its roles in aging and age-related disease.

🧠🌟🐭 Excited to share some of my postdoc work on the evolution of dexterity! We compared deer mice evolved in forest vs prairie habitats. We found that forest mice have: (1) more corticospinal neurons (CSNs) (2) better hand dexterity (3) more dexterous climbing, which is linked to CSN number🧵

Evolutionary expansion of the corticospinal system is linked to dexterity in Peromyscus mice https://www.biorxiv.org/content/10.1101/2025.10.16.682851v1

New preprint from the spinal cord group at Glasgow. Anatomical and functional characterisation of spinal circuits for cold, from sensory neurons to the brain…..https://www.biorxiv.org/content/10.1101/2025.10.03.680240v1

Labelled axons of calb1+ spinal projection neurons innervate multiple brain targets associated with cold sensation and thermoregulation. Darkfield images of different brain areas including the postal parabrachial and periaqueductal grey are shown with axons of ascending cells in yellow.

Does anyone have favorite colors for color blind friendly fluorescence images on a black background where the overlap combinations of 3 colors are important? Magenta/cyan/yellow overlaps are difficult to distinguish (lots of white) Thank you!

Happy to share my first publication with @patrikernfors.bsky.social Lab - all about the DRG: Chromatin accessibility, single cell and spatial RNA sequencing - a great source for everyone interested in sensory neurons and non-neuronal cell of the DRG 😊
