3. Hemispheric Organization

The bioRxiv preprint examines how language and attention are organized across the brain’s hemispheres. Using brain scans and family data from 987 participants, the researchers identified right-sided, left-sided, and bilateral attention patterns that were independent of handedness and varied by sex.

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.

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.

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.

• 00:02:42 — Closing

1. Attention Signals

A bioRxiv preprint highlighted in r/neuroscience examines whether degraded neural representations come before failures of sustained attention. The title points to a timing question: neural information may become less reliable before a person visibly misses the task.

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

An r/neuro post shows a project that connects an adult fruit-fly brain model to Blender and tries to make the simulated animal perform a simple action. This is a demonstration or engineering experiment, not a published study with a reported biological result.

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.

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.
