This is very interesting! As a layman, I was aware that men and women had different alcohol tolerances but had no idea that there were more crucial neurological differences.
Could it because of differences in physiology? No:
“The observed sex differences in DMS sensitivity to EtOH are unlikely to result from basic physiological properties of the recorded cells, since these properties are similar across sexes. While estrous cycle can influence female neural physiology, sampling across several weeks likely averaged out these cycle-dependent changes in the present study”
And, indeed, ethanol is an endocrine disruptor. The endocrine system, in turn, is known to influence neuroplasticity. Given that estrogen and testosterone impact neuroplasticity in the DMS via different pathways, there's a good chance that plays a role.
As wild speculation, estrogen acts as an inhibitor for long-term potentiation (or strengthening of synaptic connections), which lends mild support to the idea that it could prevent changes in outcome-related encoding. (The paper points out a possible mechanism, as footnote 72. I admit I was too lazy to read it, so it might well say that this was a really bad theory.)
In general, whenever something weird happens that has observable differences across sexes, blaming the endocrine system is a good first go-to strategy ;) Hormones are extremely powerful influences in our body.
Due to a sleep apnea diagnosis, I don't drink any alcohol anymore at all, and outside of a single White Russian at a friend's house last Halloween, I haven't had anything to drink in more than two years.
Even before that, I didn't drink a lot, and I don't think anyone would classify me as an alcoholic, but I definitely felt like when I did drink, especially if I got drunk a part of me would kind of feel "different" in a sort of intangible way, well after I sobered up, sometimes for what felt like weeks.
It's kind of hard to explain, just sort of an odd, lingering sort of ethereal feeling that persisted.
I kind of thought it was just in my head, some sort of psychosomatic thing, but now I'm wondering if it was a physiological effect that messed with my brain.
I don't miss drinking, I fortunately never really developed that vice, and now I'm glad that I never got into it. I don't do other drugs either; I don't even consume caffeine anymore, so I'm especially lame :)
I am not a chemist or a doctor, but I think the common adage is "it's the dose that makes the poison". Most stuff is bad for you if you get too much of it.
Someone made a claim. You made a claim that they are specifically wrong and the opposite is true, not that their claim is unproven. I just wanted to know what information informed your claim.
