🎇 Excited to finally share JL Romero Sosa’s publication! Results are from single-cell imaging in different subregions of rat frontal cortex during ✨de novo learning. Spoiler: everything is not everywhere all at once www.nature.com/articles/s41...

Neural coding of choice and outcome are modulated by uncertainty in orbitofrontal but not secondary motor cortex - Nature Communications

Neural mechanisms underlying flexible learning and decision-making are not fully understood. Using single-cell calcium imaging, authors here found that neurons in orbitofrontal and secondary motor cortex exhibit complementary roles in reward learning, with neurons in the former exerting a sustained role in conditions of uncertainty.

The current environment is making it near impossible to run clinical trials in the UK.
One key issue discussed in @brain1878.bsky.social
is the duplication - or worse - of regulatory oversight at NHS hospitals & universities.

CW: depression, ideation (& the brain)

Case study: stimulation of the sustantia nigra produces acute, intense depression that dissipates as soon as stimulation stops. Wow.

pubmed.ncbi.nlm.nih.gov/17561432/

(FYI: In follow-up, the individual had no mood issues 5 yrs out; whew!).

Within a couple of seconds, the patient’s face showed an expression of utmost sorrow and he started to sob and cry violently. He repeated over and over again the words ‘‘everything is so dark’’, ‘‘please doctor I don’t want to live.’’ Upon direct questioning, the patient said that he felt very depressed. The stimulation was stopped, and within 10 s, the patient stopped crying and returned to his previous mental status.

Postdoc affordability index for ERC starting grants (based on Eurozone inflation)

While in 2014, the fixed 1.5 mil EUR budget amounted to 9.84 theoretical 3-postdoc positions, in 2024 we are at 6.67, that's 32.3% loss in purchasing power.

I will just leave it here.

👁️🧠 New preprint: We demonstrate the first data-driven neural control framework for a visual cortical implant in a blind human!

TL;DR Deep learning lets us synthesize efficient stimulation patterns that reliably evoke percepts, outperforming conventional calibration.

www.biorxiv.org/content/10.1...

Diagram showing three ways to control brain activity with a visual prosthesis. The goal is to match a desired pattern of brain responses. One method uses a simple one-to-one mapping, another uses an inverse neural network, and a third uses gradient optimization. Each method produces a stimulation pattern, which is tested in both computer simulations and in the brain of a blind participant with an implant. The figure shows that the neural network and gradient methods reproduce the target brain activity more accurately than the simple mapping.

I'm now in the alternative universe where "corresponding author" (not just 1st/last author) and officially listed as "invited" talks/lectures matter. Now I have to decide what counts as invited. Like if I ask people if I can give a talk, and they "invite" me to give a talk.

Is anarchist science possible? As an experiment, we got together a large group of computational neuroscientists from around the world to work on a single project without top down direction. Read on to find out what happened. 🤖🧠🧪

Diagram of how the "collaborative modelling of the brain" (COMOB) project started. Starting material lead to group research or solo research, coming together in online workshops (monthly) in an iterative cycle, finishing with writing up together. The diagram is illustrated with colourful cartoon blob characters.

Prince of Persia was a groundbreaking game for its accurate character movement back in the late 80's. To do this, the creator videotaped his own brother running and jumping on the sidewalk and then did pixel mapping frame by frame as shown here at the Strong Museum of Play

Well the CCN GACs have no money, you just do it 😂. More for a debate and putting the arguments out there. It's true it won't solve anything immediately, but the questions are raised in an interesting way and some progress might be made.

One difficulty is nailing down what people actually think. 1) info/function is in specific brain areas vs distributed everywhere. 2) info/function is in specific areas vs it is flexible - it can depend on task/context/etc. Probably many more possible views

This is such an amazing thread (and subthreads), there are many people who might want to specify their predictions for an adversarial collaboration. Maybe you should try to organize it for the next @cogcompneuro.bsky.social GAC?
