Hello again, fediverse! 👋 I've moved here from qoto.org, which has since changed its name and had been having a lot of problems (outages, broken media) for a while. If you followed me there, please follow this account instead! For newcomers: I'm Dimos, a neuroscientist postdoc interested in neural coding, neuronal cell types and decision-making. Looking forward to reconnecting. #introduction #neuroscience

Scientists identify the rare, widely connected brain cells that appear to trigger the onset of sleep https://arstechnica.com/science/2026/09/finding-the-cells-that-put-our-brain-to-sleep/ Ars Technica reports on the identification of a population of rare neurons with unusually broad connectivity that appear to play a key role in initiating sleep - a finding that could open new avenues #science #neuroscience #sleep

Learning without a brain – how bacteria store memories and remember the past like artificial neural networks

Bacteria use strategies similar to artificial neural networks to use the past to adapt to the future.

Decoding silent reading from non-invasive EEG

Non-invasive decoding of inner speech faces a fundamental data problem: a corpus pairing brain activity with a person's spontaneous inner monologue cannot be collected, and the available proxy paradigms (cued repetitive and retrospectively reported generative inner speech) are slow to acquire, poorly time-locked, and subject compliance is unverifiable. We therefore treat silent reading as a scalable proxy task and ask how much lexical and semantic information a contrastive decoder can extract fr

Even if a complete neuron doesn't die, if a huge chunk of the synapses are destroyed, whatever that neuron was doing before, it's doing a fraction afterwards: a measurable, consistent, and symptom-correlated loss of dopamine nerve terminals averaging 18 percent across the long COVID group. with localized damage to areas that match Long COVID symptoms: “In other illnesses this magnitude of loss is associated with symptoms: loss in one region is associated with trouble with motivational energy problems, loss in another region is associated with some slowness of movement, and loss in a third region is associated with memory trouble.” in short, the terminals are gone, the loss is measurable, and it correlates with the symptoms patients have been reporting for years. https://tech-paper.com/scientists-finally-have-a-biological-explanation-for-why-long-covid-patients-lose-motivation-and-cant-think-clearly-they-scanned-their-brains-and-found-the-dopamine-system-was-physically-damaged/ #neuroscience #neurology #science #LongCOVID #PASC #health

Millions of people with long COVID report the same cluster of symptoms: a crushing lack of motivation, an inability to think clearly, memory that slips, movements that feel slower than they should. For years, these complaints sat in an uncomfortable medical grey zone. The symptoms were real, the patients were suffering, but the biological explanation remained frustratingly out of reach.A team at the University of Toronto just published what may be the clearest physical evidence yet for what is a
