In a preclinical study, rodents treated with uric acid showed improved long-term outcomes after acute ischemic stroke. The findings suggest that the treatment may work as an add-on therapy to standard stroke treatments in humans. The study is published in Stroke.

University of Arizona neuroscientists studying the brains of songbirds have found that aging alters the gene expressions that control the birds’ song. The finding could lead to earlier diagnoses and better treatments for human neurodegenerative disorders such as Parkinson’s disease and Alzheimer’s disease, which are known to hinder vocal production in their early stages.

For college athletes with concussion, brain changes may remain visible in brain scans up to a year after they are cleared to return to play, according to a study published online in Neurology.

Speech is a unique human ability that is known to be supported by various motor and cognitive processes. When humans start speaking, they can decide to cease at any point; for instance, if they are interrupted by something happening or by another person speaking to them.

Studying spinal cord injuries requires a material that can transmit clear signals yet remain flexible for when patients move around. Researchers at Binghamton University think they have hit upon a solution that will offer the best of both requirements.

Having two eyes is crucial to escaping danger, according to a new study conducted by an international team of researchers.

Physical and imagined movement through real-world environments may use the same neural mechanism in the brain, suggests a Nature Human Behaviour paper. The findings might help us to better understand human memory in real-world settings.

Poor sleep among older adults is linked to disruptions in the brain’s “waste removal system,” according to researchers at The University of Hong Kong (HKU). A recent study led by Professor Tatia M.C. Lee, Chair Professor of Psychological Science and Clinical Psychology and May Professor in Neuropsychology at HKU, offers valuable insight into how sleep quality impacts brain functioning.

A study led by University of Warwick Professor Jianfeng Feng has found that regularly sleeping too little is associated with depression and brain loss in emotion areas, while sleeping too long is associated with cognitive decline and degenerative diseases.

An abnormal form of the tau protein found to accumulate in the brains of Alzheimer’s disease patients also accumulates in the eyes of patients with the condition, according to new findings from Cedars-Sinai investigators.
