    Neuroscience Daily for 08 October: Optogenetics Nobel, Dopamine Reward Signals, Social Pain Codes

    Neuroscience Daily for 08 October follows 3 stories from r/neuro and r/neuroscience, moving through optogenetics nobel, dopamine reward signals, social pain codes. Chapters 00:00:00 — Intro 00:00:11 — Optogenetics Nobel 00:01:12 — Dopamine Reward Signals 00:02:06 — Social Pain Codes 00:03:01 — Closing 1. Optogenetics Nobel Beezloop reports that a Stanford psychiatrist is sharing the Nobel Prize in Medicine for work that helped turn light into a way of controlling brain cells. The technology is optogenetics, which uses light-sensitive proteins and carefully delivered flashes of light to activate or silence selected neurons. Source link Reddit discussion 2. Dopamine Reward Signals BioRxiv presents a preprint on how dopamine neurons communicate reward-prediction signals to the basal forebrain. In recordings from freely moving rats, activity in ventral tegmental area dopamine neurons consistently led bursts in a separate basal-forebrain population by about ten milliseconds. Source link Reddit discussion 3. Social Pain Codes Proceedings of the National Academy of Sciences is the source behind a discussion of whether social rejection shares neural mechanisms with physical pain. The original study reported overlap in somatosensory representations, which helped popularize the phrase The question raised here is how much that overlap means, since the same broad brain region can support different computations. Source link Reddit discussion That's it for today.

    Neuroscience Daily for 30 September: Brain Aging MRI, Locus Coeruleus Taste, Predictive Learning

    Neuroscience Daily for 30 September follows 3 stories from r/neuro and r/neuroscience, moving through brain aging mri, locus coeruleus taste, predictive learning. Chapters 00:00:00 — Intro 00:00:11 — Brain Aging MRI 00:01:22 — Locus Coeruleus Taste 00:02:25 — Predictive Learning 00:03:40 — Closing 1. Brain Aging MRI Brain scans reveal which disorders are linked to faster brain aging, according to ScienceDaily’s report on a PLOS Medicine study. Researchers compared structural MRI data from 45,900 control participants with scans from 2,698 people across Alzheimer’s disease, mild cognitive impairment, addiction, schizophrenia, bipolar disorder, major depression, ADHD, and autism. Source link Reddit discussion 2. Locus Coeruleus Taste A paper summarized in Neuroscience examines how activating the locus coeruleus changes taste representations in the gustatory cortex. Using optogenetic stimulation and miniscope imaging in mice, the researchers compared brief, phasic activation with tonic activation while tracking neural responses to taste. Source link Reddit discussion 3. Predictive Learning A bioRxiv preprint asks whether predictive learning rules explain human neural representations better than standard supervised deep networks. The authors compared small, otherwise matched networks trained with predictive, contrastive, or supervised objectives, and also compared local learning with full backpropagation.

    Neuroscience Daily for 27 September: Childhood Epilepsy, Riluzole And Glia, Brain As Computer

    Neuroscience Daily for 27 September follows 3 stories from r/neuro and r/neuroscience, moving through childhood epilepsy, riluzole and glia, brain as computer. Chapters 00:00:00 — Intro 00:00:10 — Childhood Epilepsy 00:01:12 — Riluzole And Glia 00:02:16 — Brain As Computer 00:03:08 — Closing 1. Childhood Epilepsy This story is about how human brain organoids are revealing a possible cause of childhood epilepsy, in a study published by Nature. Researchers modeled tuberous sclerosis complex by removing both copies of the TSC2 gene in selected human brain cells, then tracked what happened as the organoids developed. Source link Reddit discussion 2. Riluzole And Glia The second story concerns riluzole and memory in a rat model of Alzheimer’s-related toxicity, reported in the Journal of Neuroinflammation. Researchers injected amyloid-beta oligomers into the hippocampal CA1 region of male rats and gave the animals riluzole for seven days. Source link Reddit discussion 3. Brain As Computer The final story asks whether the brain is really best understood as a computer, in a review from Cognitive Wonderland discussing Romain Brette’s book The Brain, In Theory. The argument is that the computer comparison can quietly make researchers treat the brain as a passive device that receives inputs, while unexplained activity gets labeled noise. Source link Reddit discussion That's your five minutes.

    Neuroscience Daily for 26 September: Southern Europe Neurotech, Epilepsy Astrocytes, Amygdala Cell Map

    Neuroscience Daily for 26 September follows 3 stories from r/neuro and r/neuroscience, moving through southern europe neurotech, epilepsy astrocytes, amygdala cell map. Chapters 00:00:00 — Intro 00:00:13 — Southern Europe Neurotech 00:01:09 — Epilepsy Astrocytes 00:02:12 — Amygdala Cell Map 00:03:12 — Closing 1. Southern Europe Neurotech The first story is a new map of neurotechnology companies in Spain, Portugal, and Italy, shared through the Neurotech Newsletter. The survey counts 63 selected core and enabling companies, spanning brain-computer interfaces, biosignals, neurorehabilitation, assistive robotics, and clinical tools. Source link Reddit discussion 2. Epilepsy Astrocytes The second story comes from Berkeley News, covering a Nature study of childhood epilepsy linked to tuberous sclerosis complex. Researchers grew human brain organoids carrying mutations in the TSC2 gene and found that astrocytes became hyperreactive as they developed, with gene and protein patterns associated with inflammation. Source link Reddit discussion 3. Amygdala Cell Map The third story is a bioRxiv preprint titled The work uses spatial transcriptomics to connect gene-expression patterns with the physical organization of cells across the human amygdala. That matters because the amygdala is often discussed as a single fear and emotion center, even though its subregions contain distinct cell populations and circuits.

    Neuroscience Daily for 23 September: Human Brain Is Two, New Study Links Deep, New Study Uses Neural

    Neuroscience Daily for 23 September follows 3 stories from r/neuro and r/neuroscience, moving through human brain is two, new study links deep, new study uses neural. Chapters 00:00:00 — Intro 00:00:07 — Human Brain Is Two 00:01:09 — New Study Links Deep 00:02:08 — New Study Uses Neural 00:03:18 — Closing 1. Human Brain Is Two Stanford Medicine reports a study suggesting that the human brain develops from two distinct neural progenitor systems. The researchers traced one pathway toward the forebrain and midbrain, and another toward the hindbrain, which manages automatic functions such as breathing, swallowing and heartbeat. Source link Reddit discussion 2. New Study Links Deep Nature Neuroscience reports a human study connecting Alzheimer’s-related tau in the frontal cortex with changes in deep non-REM sleep waves. Researchers combined tau PET imaging, sleep EEG and memory measures in older adults, then checked the relationship against an independent group using cerebrospinal-fluid markers. Source link Reddit discussion 3. New Study Uses Neural The University of Utah describes a study using neural networks to model how structured experience shapes learning. Researchers trained networks on a timing task that was modeled on a mouse experiment, comparing a gradual path from simpler trials with a direct jump into the full task.
