Researchers have found that ADHD brains briefly enter sleep-like states during wakeful, demanding tasks — a neural pattern directly linked to attention lapses, slower reaction times, and more frequent errors.

A new study in mice suggests psychedelic compounds make the brain prioritize stored memories over real sensory input — causing perception to be driven by internal models rather than present reality.

Researchers warn that exposing young children to AI-generated content during critical developmental windows could have lasting consequences for cognitive and social development.

Researchers have identified an overlooked neural pathway linking the brainstem and spinal cord that controls hand movements, revealing new targets for stroke rehabilitation.

A biocomputing startup is building the first data center using lab-grown human neurons as processing units, promising dramatic energy savings over silicon.

Eon Systems has connected a complete fruit fly brain emulation to a virtual body, simulating over 125,000 neurons and 50 million synapses.

UCL researchers decoded neural signals to recreate movies mice had watched, advancing brain-computer interface research.

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.

Researchers have pinpointed a molecular weak spot in anti-NMDA receptor encephalitis, the devastating autoimmune condition known as 'Brain on Fire.' The discovery opens the door to targeted therapies for a disease that attacks memory and cognition, causing psychiatric symptoms, seizures, and death.

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.
