DMT-induced shifts in criticality correlate with self-dissolution

Psychedelics profoundly alter subjective experience and brain dynamics. Brain oscillations express signatures of near-critical dynamics, relevant for healthy function. Alterations in the proximity to criticality have been suggested to underlie the experiential and neurological effects of psychedelics. Here, we investigate the effects of a psychedelic substance (DMT) on the criticality of brain oscillations, and in relation to subjective experience, in humans of either sex. We find that DMT shifts the dynamics of brain oscillations away from criticality in alpha and adjacent frequency bands. In this context, entropy is increased while complexity is reduced. We find that the criticality shifts observed in alpha and theta bands correlate with the intensity ratings of self-dissolution, a hallmark of psychedelic experience. Finally, using a recently developed metric, the functional excitatory-inhibitory ratio, we find that the DMT-induced criticality shift in brain oscillations is towards subcritical regimes. These findings have major implications for the understanding of psychedelic mechanisms of action in the human brain and for the neurological basis of altered states of consciousness. Significance statement Criticality is characterized by fluctuations occurring on a wide range of spatiotemporal scales and high complexity. Here, we investigate the effects of DMT, a classic psychedelic, on criticality of brain oscillations and in relation to subjective experience. We find that DMT shifts the normally dominant alpha oscillations towards a quieter subcritical state, increasing entropy while reducing complexity, and that this shift correlates with intensity of disruption of the sense of self.

NSFW: 이상성욕 관련

어느 BDSM 포르노 영상의 등장인물 'Rose'의 의상이 영화 "체인소맨 레제편"의 캐릭터 '레제'와 매우 유사하다는 논란
심지어 Rose 역을 맡은 배우가 러시아 출신인데다가 등장인물 이름도 '레제'와 비슷해서 후지모토 타츠키가 그 포르노 영상물에서 레제 디자인을 가져왔다는게 기정사실화 되고있다고 함
사실 후지모토 타츠키의 과거 행보들을 보면 이상하지 않긴 함... 워낙 유별난 사람이라

쿠팡은 로그인, 결제 정보는 안 털렸다고 변명하고 있는데, 이 사건은 매우 치명적임.

이름과 전화번호를 알면 주소, 그 것도 실생활하는 주소를 알 수 있게 되었음. 누가 이 정보를 가장 욕심낼까? 이 사람 지금 어디에 사는지 알아내려는 자들이 누구일까?

쿠팡 고객들은 이제 집과 직장을 모두 까발린 상태가 된 것임. 정부의 매우 적극적이고 단호한 제재가 필요함. 털린 정보의 유통도 끝까지 추적해야 할 상황임.

The president has illegally declared war to stop fentanyl trafficking from a country that does not traffic that drug, claiming its leader is trafficking drugs himself, the day after pardoning a former leader of a country who is a convicted drug trafficker. Just to level set

Do you ever think about "doubly special relativity" and get upset

This is pretty obscure

The idea is: The planck length is supposed to be an inviolate limit, but if Lorentz contraction occurs (IE length contraction when something is moving at relativistic speeds), then the effective planck length changes. Observers in different inertial reference frames will measure a different planck length for the same object.

My wife got a family subscription for Duolingo. Now I'm one them... It's actually pretty fun but it has had some unintended consequences. Every once and a while Oscar says "look who's back, back again" and I end up with Without Me by Eminem stuck in my head. For days...

かねひさ和哉 (@kane_hisa) on X
今のSNSは企業や著名人がマイノリティへの配慮を表明すると(残念ながら)相反する立場の方から半ば反射的な怒りの反応が殺到してしまうことが多く、「炎上」リスクや精神的な負荷を鑑みてほとんどの人々が萎縮してしまう状況なんだけど、そんな中でも声を上げる良心と勇気を持った方がいて嬉しい x.com/kane_hisa/status/1994785

Edit: what's below is wrong -- the workflow on @b0rk_rerunsJulia's Reruns Bot's "Oh Shit, Git" site is indeed symmetric for making a commit to the wrong branch. I'm considering a PR to clarify that.

For posterity, my erroneous question is below. I think I got confused because, in the second example, I wasn't switching branches the way I thought I was...

--------------------

Git folks: I'm looking at @b0rkJulia Evans's Oh Shit, Git thing for when you commit to the wrong branch and want to move the top commit elsewhere.

For a commit to main, you have:

# create a new branch from the current state of master
git branch some-new-branch-name

# remove the last commit from the master branch
git reset HEAD~ --hard

# move to the new branch
git checkout some-new-branch-name

That works. But if the original branch isn't main, it doesn't. I don't understand why: main is just another branch, right?

When I do the above while on the topic1 branch, the commit just goes away. (Well, it's in the reflog.) Why didn't it do that when I was on main?
