- At #ACNP2026? Come see my poster (W45, 5–7 pm)! We @erika-forbes.bsky.social find that immune activation and basal ganglia dopamine availability interact and relate to anhedonia among youth w/ depression, with evidence for anticipatory and not consummatory anhedonia. Preprint is now available!
- Thank you @acnporg.bsky.social for the ACNP Travel Award to make this opportunity happen, and Erika Forbes for nominating me for this award!

They don't act directly on the brain’s attention systems! Find out what's really happening in @cellpress.bsky.social. doi.org/10.1016/j.ce...

- Reposted by Iris Ka-Yi ChatI’ve spent the last 8 years(!) working from the position that HiTOP relies too much on analyses of traditional diagnoses, baking in limitations of the DSM, and that we need to move to symptom-level analyses to fix it It turns out that rebuilding HiTOP from the ground up doesn’t change much 💀 1/
