The researchers followed 7,489 young people from the Adolescent Brain Cognitive Development Study and used statistical weighting designed to probe possible causal effects.

2. Tau Brain Organoids

A bioRxiv preprint reports that Alzheimer’s tau filaments can be seeded in human cortical organoids. The researchers added tau seeds extracted from Alzheimer’s disease frontal cortex to organoids made from human induced pluripotent stem cells, with the cells producing their own normal levels of three-repeat tau.

3. Dendritic EEG Model

An article in Neural Computing and Applications introduces a recurrent neural-network design called the Dendrite-Inspired Recurrent Unit, or DIRU, and tests it on neonatal EEG. The architecture splits each recurrent cell into several nonlinear compartments, then uses learned attention weights to combine them into a shared hidden state.

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.

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.

2. Brain Pain

An r/neuro discussion asks why the brain itself does not seem to have pain receptors while the tissues around it do. The answer is that much of the brain's neural tissue lacks the nociceptors that detect tissue damage, while the meninges and some blood vessels can generate pain signals.

3. Fruit-Fly Simulation

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.

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.

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.

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.

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.

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.

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.

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.
