We argue that visual hallucinations in psychedelics and Lewy body disease may share common mechanisms ⇒ visual degradation & cortical excitation.

Today, Trump declared war on his own citizens, calling for U.S. cities to be used as “training grounds” for troops to confront what he called an “invasion from within.” Americans are a proud people, and no one (foreign or domestic) will threaten our home.

great work with Megan Hosein, Zach Cordner, and the NNDC Task group on psychedelics and related compounds - grateful to co-chair with @TrishaSuppesMD
1/ New consensus statement just dropped on the potential for psilocybin in clinical care, from the Task Group on Psychedelics and Related Compounds of the US National Network of Depression Centers
The message? Lots of promise, but real risks if we rush. 🧵

I'm a member of the NIMH BSC. The members who were fired are outstanding scientists, which is why they were appointed to the BSC in the first place. Their firing for unspecified reasons is unconscionable.
At least four neuroscientists received termination letters this week dismissing them from NIH advisory boards. “This is unusual and unprecedented,” says @thebalelab.bsky.social, one of the terminated board members.

gotta celebrate all small victories - I just passed 10k citations on google scholar :) only legit peer-reviewed articles (this can be a fickle and deceptive number depending on what items make it on the list).

For the democrats saying “we can’t let the govt shut down” you’ve already lost. It’s not on you.
Republicans control everything, didn’t come to you for anything except your vote. Where else can you force changes? You can’t… you’re a willing participant in Republican majority

bullying smaller or less capable people (countries) is not a sign of strength. generosity and support is not weakness. having people’s backs is not equivalent to being taken advantage of. we were stronger when we believed in the value of our own moral imperative, and when we acted accordingly.
