Researchers have demonstrated that transplanted neural stem cells can help preserve vision in models of retinal degeneration, offering a potential treatment pathway for conditions that currently have no cure.

Researchers at UC Santa Cruz have demonstrated that lab-grown brain organoids can process information in real time and learn to solve problems through trial and error. The mini-brains improved their success rate on an engineering balance test from 4.5% to 46% using reinforcement learning.

Badacze zidentyfikowali słaby punkt molekularny w encefalitis anty-receptora NMDA, niszczycielskim stanie autoimmunologicznym znanym jako 'Mózg w ogniu'. Odkrycie otwiera drzwi do ukierunkowanych terapii dla choroby atakującej pamięć i zdolności poznawcze, powodując objawy psychiatryczne, napady i śmierć.

Researchers have found that Chlamydia pneumoniae, a widespread bacterium known for causing respiratory infections, can invade the brain and retina where it persists for years, triggering inflammation and amyloid-beta accumulation linked to Alzheimer's disease. The discovery opens new avenues for early detection through retinal imaging and potential antibiotic treatments.

A newly identified ion channel called TRPV4 acts as the brain's internal braking system for scratching, sending a 'that's enough' signal through sensory neurons. The finding could reshape how researchers develop treatments for chronic itch conditions such as eczema and psoriasis.

Researchers from the University of Southern Denmark and Bern University Hospital found no evidence that the rat brain produces or stores DMT in serotonin-releasing neurons, undermining a decades-old hypothesis about the psychedelic compound's natural role in brain chemistry.

Penn State scientists discover that a nanoscale lattice under the neuron membrane acts as a gatekeeper controlling amyloid-beta accumulation.

Scientists identify a neuronal mechanism that controls amyloid-beta accumulation in the brain, offering a new target for slowing Alzheimer's disease progression.
