It is always interesting when somebody my age discovers something that is important and new (to me).
I did not know that personality disorders were invented in Nazi Germany to get rid of undesirable people. Innate, untreatable, undesirable = sterilize, murder.

We’ve just published another video on HiTOP that tries to flesh out a bit more how the framework can be helpful in research: youtu.be/q0jOi_Nl1yo

We hope it’s useful, and are keen to hear any feedback

Thanks again so much to @tashtc.bsky.social for all of her hard work creating this video series ✨

8/n. Yet, in contrast to work in humans and animals outside the scanner, imagers have yet to tackle this fundamental question. Why? Generally, the ITI contributes to the implicit baseline in std 1st-level fMRI GLM's, and std (uncalibrated) fMRI is insensitive to slow signals (1/f noise), h/t RikH

7/n. it's effectively a (complex) cue indicating p>0 of future threat encounters (p=1 in mouse & DeGeneres; p=0.5 in Lissek; p>0 in NHP). It's sensitive to BST/BNST function & loss-of-function pubmed.ncbi.nlm.nih.gov/19692610/

While learning to fear stimuli that predict danger promotes survival, the inability to inhibit fear to inappropriate cues leads to a pernicious cycle of avoidance behaviors. Previous studies have reve...
