Physio question for #neuroskyence: This figure shows that global BOLD signal is already increasing before the onset of electrodermal spikes (t=0), and falls rapidly afterwards. I get the same pattern in my dataset (also for event-related analysis, GS peaks at t=0). What are potential explanations?

Some more figure drawing this morning. Still working the mechanical pencil, though a more rigid one this time

Need some #neuroskyence advice: What would an interpretation be for massive hypoconnectivity between one region (e.g. OFC or accumbens) and the rest of the brain as a function of a between-subjects variable Z? I.e., the mean of all edges for that node decreases as you go up in Z.

With some trepidation, I'm putting up an article I wrote in 2023 on my personal site. It documents a visit I paid to a friend in a psychiatric intensive care unit that I found quite disturbing and depressing. I offer a little commentary at the end.

I put up an old essay I wrote for a history and #philosophy of #science course on PsyArXiv. It's an overview/exploration of psychosomatic syndromes through the last 150 years or so. I think it still holds up despite writing it back in undergrad!

To my #Montreal peeps, I'm accompanying my tall friend Danny Barwick at his gig at L'Escogriffe on Thursday, on the accordion, along with my sis on the violin. Come through for some dreamlike ballads ✌️

This is the kind of paper that makes me wonder, "have we learned anything in the last hundred years?". You hear about the James-Lange and Cannon-Bard theories for all of a out 5 seconds in psych 101, but there are so many interesting threads in this 1927 pub. #neuroskyence

A big part of the debate between cognitive an precognitive theories of emotion seems to boil down to the question: Can you feel an emotion without being aware of it?
So, can you? #psychscisky #neuroskyence #philosophy

We tried to put together some of the unique challenges about studying emotions (in contrast to other subjective experiences) + what is causing this divide between theories and experiments (which for one seems disagreement on what to study) in this paper: academic.oup.com/nc/article/2...

Abstract. The search for neural correlates of emotional consciousness has gained momentum in the last decades. Nonetheless, disagreements concerning the me

@nicolecrust.bsky.social Congrats on what has to be the most massive affective neuro thread on bsky so far, by a long shot (take a look at it on a thread unroller and wow...)
As I try to wrap my head around my new field of affective science writ large and The Theory of Constructed Emotion specifically, @elisennesh.bsky.social has been helpful. For the many here who like to discuss "how we sciene", my sense is that TCE is a different approach than other ways.

Re: the Theory of Constructed Emotions, I generally try to stay theory-agnostic, but I find I have a definite attachment to "realist" emotion theories. In general, the way I approach psychology and emotional intelligence is as a dialectic between me (my ego) and things in me that I can't control

Revisiting Julian Jaynes, and this is something almost word-for-word that I often think about hypnosis. An aspiring global theory of cognitive or brain architecture needs to have something to say about it. Thoughts? #neuroskence #psychscisky

Folks interested in and/or working in #neuroskyence #psychscisky, what are some questions you have with respect to dissociation, derealization, repression, and mind-body connectedness?
No answers, just interested in questions :)

The more that I learn, the more I become anxious that I haven't learnt enough 😬 The curse of a generalist, maybe.
On a related note, any advice for a PhD student about comprehensive exams?

In an interview with Mark Solms, @dariusparviziwayne.bsky.social presses the question of whether the "synthetic a priori function of consciousness" may be feeling, or whether the function of feelings could be performed by something unconscious (like a loss function in an artificial neural network?).

If you take magic mushrooms, at increasing doses, your thoughts and perceptions decohere. Eventually, you might lose all sense of time, space, location, and the distinction between self and not-self. Eventually, you are just awareness - BUT, an emotional awareness. Affect is still coherent.

Mark Solms talks about a Patient W he had who had basically his entire frontal lobes (apart from Broca's area) surgically removed as a teenager, due to repeated post-operational infections. This patient was fully conscious (in the responsiveness sense) and reported having mental imagery.
