If we give up on the idea that there are discrete mental disorders as natural entities to be “discovered” and accept that we are dealing with a messy, dimensional landscape of psychopathology that can be mapped in many different ways, there is no problem at all with the idea that we can classify and map this landscape in different and better ways than the psychopathologists and nosologists of the past.
1/18: Well, after 23 years as faculty at Harvard and almost 15 years of amazing collaborations, collegiality and growth at McLean Hospital, today I officially start at @UCIrvine, where I will be the founding director of a new depression
Here's the thing. We have **NO IDEA** how to pick good graduate students. I served on admission committees for 10+ years, and chaired a few, and what I learned is that all the spreadsheets of grades and test scores and recommendations and essays and publications and interview rubrics are just an elaborate ruse to pretend we know what we're doing when we simply don't. Many of the most highly ranked applicants to our "top" program flamed out quickly, and tons of the students we summarily rejected have turned into amazing scientists. But in the name of creating meritocratic seeming rankings that are more about creating a workforce than great scientists (a system that anyone paying attention knows is bullshit), we've created a homogenous process adopted by nearly all institutions that has stamped out the one thing we should be striving for - given our lack of any clear understanding of what leads to success - a wide range of difference talents and experiences.
qPCR can measure expression of virtually any gene... in homogenized tissues. Here, we show an "in-vivo qPCR" equivalent, where we measure a sequence-specific transcript with synthetic serum markers and enzyme-based signal amplification.

Finally, we searched for receptors that are enriched on these putative anxiety-related intercalated cells that lie along the border of the central nucleus of the amygdala. Excitingly, we found a receptor that might be explored for the development of new treatments: NPFFR2.

An examination of relative enrichment of genes that have been implicated in amygdala-related disorders in humans. We were somewhat surprised to identify intercalated cells as enriched for genes associated with neuroticism and anxiety disorders.

Check this out! @EricJNestler and I co-edited this PNAS special issue:
The Neurobiology of Stress: Vulnerability, Resilience, and Major Depression | Proceedings of the National Academy of Sciences | Proceedings of the National Academy of Sciences https://t.co/4k90tKtP0Q
Riding the ACNP twitter wave, check out my new paper which includes the bulk of my thesis work in this amazing special issue. If you like nonhuman primate transcriptomics (including some single cell!), anxious temperament or me, this one is for you!
@CarlosEAlvare17 @ajshackman Could be. The utility will depend on the conservation of the underlying mechanism, and homology of the phenotype. It is most certainly a viable strategy that is worth pursuing. :-)
@ajshackman That may be true, but don’t throw the baby out with the bath water. Self-report will always have limitations, and we have no consensus on what behavioral phenotypes would lead to this level of success. My hunch is that we are further from that than you might think…
