Am I the only one who finds the NIH focus on age at first R01 a little unseemly? . I get that it’s meant to limit extended postdoctoral periods, but I don’t know that it’s working and it’s kinda ageist & kinda exclusionary of alternative life experience.

It purports to debunk that depression is caused by disruptions in serotonin function “It is often assumed that the effects of antidepressants demonstrate that depression must be at least partially caused by a brain-based chemical abnormality” 1/n.

This view truly perplexed me. Do folks believe that there is a mind that exists, untethered from biology, upon which psychosocial factors & psychotherapy operates???. How does this view account for the biological phenomena (like brain activity) associated with mental processes?.
I believe it is becoming abundantly clear that amongst mental disorders, there are a few true psychiatric diseases (biological etiology and pathophysiology) and many more "clinical pictures," in which there may be a biological *component* but the etiology is largely psychosocial.

Oh dear. Plus this shocker “Shockingly, there has yet to be a K99 awardee at a historically Black college or university.”.
The time between a researcher starting an R00 award and receiving a major NIH award/R01 is 4.6-7.4 years, and is significantly longer for women and those who remain at their home institution.

I’m madly proud of my big sister, Elana Harris. With her MD-PhD in neuroscience and child psychiatry training, she was on a successful academic research track. But she couldn’t stand idly by while the opiate crisis burned on, so she founded this program

Stoked to attend #acnp2021 as a #newPI! Our lab studies how stress impacts circuit activity underlying reward seeking and cognition. @ACNPorg and @npp_journal: it’s gonna be a great conference!!!.

Nearly 5 years ago, my mentor @nimhdirector left for the NIMH. TBH, it was frightening, but I remained in NY & guided the group of postdocs and grad students that stayed at Columbia. I was adopted by @rene_hen and learned a LOT about running a lab! 2/4.

NIH directors recommend asking for “for cost” extensions in the last year of grant budget. Unofficial priorities in the absence of official budget are early career investigators, women, and minorities. Reach out to PO #acnp2021.

And the paper is going *prove* it’s point by showing a lack of association between serotonin levels and depression… which is a grossly simplistic idea that ignores the vast known complexity of how serotonin modulates the brain.

In a remembrance, Dr. Justin Richardson wrote that she gave the parenting advice “psychoanalysis is what we give our patients; CBT is what we do with our kids.”.
I just learned that my residency director, Dr. Betsy Auchincloss, passed away. She was a brilliant mentor who demanded excellence & I’m eternally grateful that she carved out a residency spot that fully accommodated my religious observance & had protected time for research.

Love this thread! As a psychiatrist & neuroscientist who studies the circuits underlying psychiatric symptoms in mice, I find ACNP a warm community of smart folks doing a broad range of interesting science. Looking forward to seeing old friends & making new ones!#ACNP2022.
Hey @ACNPorg members/mtg regulars - getting back into the swing of conferencing is challenging, so we'd like to extend a warm welcome to #ACNP2022 for early career folks and people new to ACNP. Would love if you could introduce yourselves to kick off the mtg and welcome everyone!

That is NOT what happened! Luke cogently explained both on and off manifolds! It was great! But we did leave before he finished the extra fries… it was *very* late.
Drunkenly stumbling back to my #SfN2022 hotel last night, I was accosted by two colleagues who were like LUKE YOU HAVE TO EXPLAIN #MANIFOLDS! So we sat down in a pizza place, and when I started they were both like I DON’T UNDERSTAND I HAVE TO LEAVE and left me there.

@DrNancyPadilla & I had a lot of fun writing about this cool new paper which reports a novel, non-violent, subordination method that potently (only 4 days!) produces long-lasting changes in social rank, reward seeking, & coping style 1/3.
The discovery of a neuronal loop activated when mice unexpectedly become less dominant could provide insights into a range of stress- and depression-related behaviours, says @DrNancyPadilla & @dr_alexharris

@Franklandlab A key shift in NIMH thinking is about “depression-like behavioral phenotypes” per se. @NIMHDirector introduced the (much groaned over) distinction between models “of” and “for” to push for behavior that reveals the biology underlying symptoms rather than stamp as “translational”.

The NIH budget remains flat. Increased NIH spending on higher postdoc salaries (good & necessary!) means less spending elsewhere. If I understand correctly, this proposal would fund fewer postdocs at higher salaries by capping at 5 years. 1/3.

Two things can be simultaneously true: 1. It’s important to include male & female mice in studies AND 2. The variance between humans and mice is greater than between males and females.

@drkateking @callme_Peabody It could be semantic. We do emotional labor, and that labor is more challenging when it involves a lot of negative affect. In the end, we are human beings and our emotions are impacted by those around us.

Very thoughtful & useful piece! Love it! Couple of reactions: 1. Does chronic stress meet the threshold of anhedonia + 3 symptoms that last 7 days post stress (cf Krishnan et al 2007)? 2. Are the messy constellations of clinical depression worth recapitulating in basic research?.
Have you used the term "depression-like" in your mouse or rat study? We are of the opinion that the term is used often inappropriately and much more rigor needs to be applied for valid and meaningful #translational #psychiatry. Just out in @molpsychiatry .

I don’t know the magic ticket to getting into PhD programs, but I do know applicants who have gotten accepted into “top programs” without any publications. Let’s not play into this demoralizing narrative.
If applicants with 2 co-authored papers aren’t making it to the top 10 of a PhD applicant list, I’d wager that those in the top 10 are bringing a good deal of privilege, connections, and opportunities. I'm really not sure that 'passion' is doing any of the heavy lifting here.

Anyone have any thoughts about why postpartum depression differs from major depression?.
Now covering zuranolone, the oral version which has onset of action 3 days after initiating treatment in PPD. But interestingly, while effective in postpartum depression, a trial on major depression didn’t meet its primary endpoint #acnp2023.
