At @neuromatch.bsky.social, we tackle all these concerns by offering extremely affordable (or even free), truly accessible training in computational neuroscience & related disciplines. With Neuromatch Academy, Impact Scholars, & more we tick all the boxes -- except an actual degree (for now...?)!

Antipsychotics reduce cortical thickness in some brain regions more than others. Do underlying brain features mediate this?
Looks like, among other things, serotonin transporter and serotonin 2A receptors matter for antipsychotics related cortical thinning.

We got our CIHR dissemination grant rejected today. That's a bummer for the Canadian network for research in schizophrenia and psychosis event we are planning in May. But because the selection was randomized it did not hurt. I wish more grants were randomized.
