If I've understood them, the range of symptoms* comes about due to inappropriate serotonin production in certain serotonergic neurons (brainstem raphé nuclei and limbic system). These neuronal pathways control the response to homeostatic threat. Under certain conditions the threat response can fail to return to normal after the threat has resolved and leaves the system in a self-perpetuating, heightened state of alert.
The elevated response is said to be caused by sustained reversal of the positions of Corticotropin Releasing Factor Receptor types 1 and 2, where normally CRFR1 is on the neuronal cell membrane and CRFR2 is in standby mode in the cytoplasm. Their drug is targeting the (now membrane-bound) CRFR2 receptor, aiming to overactivate it so that it declares game-over and reverses positions with CRFR1, bringing the neurons back to their normal threat posture. I.e. DEFCON1 back to DEFCON5.
I think this proposed mechanism is analagous to the metabolic trap and the glial activation hypotheses, but is a completely different mechanism. Michael VanElzakker is not a fan and has tweeted that the neuronal systems under discussion are those responsible for learned helplessness / conditioned defeat.
*In the paper, serotonin-related functions governed by this homeostatic threat response are said to include emotion, motivation, memory consolidation, motor control, sensory sensitivity, respiration, thermoregulation, and downstream autonomic, endocrine, metabolic and immune actions.
I’d say that funding equipment is different than funding research. - it makes people wonder what a neuroscientist would do with a microscope when he has access to a 7T MRI- i am quite happy to be wrong on that, and i have not read the whole thread.Seems to me that the OMF has a thing against microscopes - Ron was appealing for donations recently to purchase one. With the millions that OMF apparently had spare you would have thought they could fund it.
I am concerned some of AP comments will add to mainstream skepticism and deter others from joining this area.

Yes. The problem is that she speculates with no data. There is a whole thread on here with Jonathan Edwards challenging her speculations—with AP stating that JE wasn’t up to date with his knowledge. If AP has collected one piece of data then by all means correct me.
But it is a problem that mainstream outlets in the US like the Washington Post are quoting her and not people like Ron Davis and others who have data.
This was the thread, from 3 years ago. I think the problem in this instance was that Amy Proal published a hypothesis article that some found unconvincing.I’ve not seen or read the thread you mention.
