Timely piece on the importance and safety of “gain-of-function” research, from my brilliant PhD advisor Sarah Stanley www.statnews.com/2025/10/06/g...
The NIH ordered me to stop my ‘dangerous’ gain-of-function research. It isn’t dangerous at all
Safe gain-of-function research is necessary to identify new treatments for diseases like for tuberculosis — but the NIH has imposed unfounded stops.

a must read for anyone interested visual cortex plasticity - a fresh look at some textbook models and a fun read. congratulations to the authors!
A Critical Look at Critical Periods

Great review of the critical period in the visual cortex. Nice evolutionary perspective, covering the key papers and mechanisms, and proposing a continuous process of plasticity that already starts before eye opening.

The lab's first paper is out!

We find that pupil constriction in mice drives strong retinal activity in vivo, and that humans can also perceive pupil-shaped stimulus. This has repercussions for anybody using pupillometry.

Thrilled to share our new Adesnik lab paper!!
Using holography in excitatory & inhibitory neurons, we reveal how a single cortical circuit can both complete and cancel predictable sensory activity, sharpening representations

Turns out that the “loudest” neurons are not always the most relevant ones. Great article about a fascinating and important result by @hayleybounds.bsky.social , graduate of @ucberkeleyofficial.bsky.social neuroscience.
Thanks to @thetransmitter.bsky.social and @ldattaro.bsky.social for this coverage of our recent paper!
Some neurons respond more strongly to visual stimuli than others. But the rest of the brain doesn’t prioritize signals from those neurons, according to a new study. Read more in this month’s Null and Noteworthy.
