Excited to share my first doctoral paper which was just published at Psychiatry and Clinical Neurosciences! doi.org/10.1111/pcn.... In this research letter, we showcase our take on the "Synthetic Image Evolution" method, in which we use genAI and evolutionary algorithms to... #neuroskyence

Wrote a little microblog on some thoughts on interoception and emotion, curious to hear what y'all think and might develop it into a longer blog post if it sparks any interest :) @nicolecrust.bsky.social @micahgallen.com #neuroskyence

Is emotion interoceptive? While I think the role of emotions is basically a kind of conscious representation of a cost function, in line with recent frameworks like "homeostatic" or "interoceptive" reinforcement learning, I'm not convinced that the basis is really in the internal sense of the body.

I set up a Bandcamp to host a bit of music I wrote for a game jam this past weekend, hopefully more such projects to come :) dariusvalevicius.bandcamp.com/album/fear-n...

Still waiting to hit a wall with CEMI field theory. I've sent it to two physics grad student friends who say the physics is sound - no evaluations yet from any computational neuroscientists! Surely someone can poke a hole in this for me? #neuroskyence

Does anyone fuck with the CEMI field theory of consciousness? Compatible with recent work on ephaptic coupling championed by @earlkmiller.bsky.social and surprisingly parsimonious... Briefly, the unconscious mind == classic neural computation, concious mind == EM field computation

I had a transcendent experience after watching Resurrection (2025) in the cinema. Standing on the sidewalk chugging cigs for 25 minutes, staring wide-eyed down the street waiting to come back to reality.

I think we made a mistake when we stopped being little rat creatures, and a second mistake when we accepted modernity. Grooming, cuddling, co-sleeping with your fellow rats, all lost to time.

This came up in a paper (Yin 2014) on basal ganglia control of movement. It reminds me of a critique I had of Feldman-Barrett's predictive processing theory of affect - it seems computationally intractable to predict, with a forward model, the metabolic consequences of everything that happens...

"Yet modern man feels uneasy and more and more bewildered. He works and strives, but he is dimly aware of a sense of futility with regard to his activities. [...] While becoming the master of nature, he has become the slave of the machine which his own hands built." (E. Fromm 1947)

I'm setting up a little Discord server for informal #neuroskyence discussion and project support (also open to psych and philosophy folks). Trainees especially welcome! I like this platform but sometimes it's a bit tricky to keep a good conversation going :) DM me for an invite if interested!

Continuing on the reservoir business, I feel like "echo state network" (another name) is a good description of how it feels to be conscious - echoes of the previous few seconds and snippets of old memories mixing in with the present moment.

Currently obsessed with the concept of reservoir computing - has anyone in the #neuroskyence community looked at this in depth? It seems like thinking of association areas as reservoirs is potentially very powerful, a way of operationalizing Buzsáki's "inside out" hypothesis.

As I'm gearing up to start my own #neuroskyence projects, I have a sort of desperate urge to make sure my time is spent on things that are going to be truly useful to someone, e.g. mental health clinicians and the people they serve. If you're a clinician: What would useful knowledge look like?

I watched The Secret of NIMH (1982) (the animated film about the mice) after only recently connecting the dots and realizing it referred to the National Institute of Mental Health. Nice to see my field represented in the media, if only as an ominous and faceless font of dispassionate cruelty :)

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?

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. dariusliutas.com/blog/psych_i...

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 doi.org/10.2307/1415...

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

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

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.
