Ultrasound device enables precise non-invasive stimulation of deep brain regions

An ultrasound device that can precisely stimulate areas deep in the brain without surgery has been developed by researchers from UCL and the University of Oxford, opening up new possibilities for neurological research and treatment of disorders such as Parkinson's disease.

Prefrontal cortex biopsies during deep brain stimulation surgery do not increase risk of adverse events

Obtaining prefrontal cortex biopsies during deep brain stimulation (DBS) surgery in living patients does not increase the risk of adverse events or cognitive decline compared to standard DBS procedures that don't involve biopsies, a team of clinical research scientists at the Icahn School of Medicine at Mount Sinai has demonstrated.

Discovering the sweet spot for listening in reverberant spaces

Hearing researchers at Macquarie University have shown that listeners rapidly learn and adapt to the characteristics of acoustic spaces to improve their understanding of speech and have found evidence for the brain mechanisms involved in 'listening to the room'.

Smell loss emerges as the early behavioural sign of Alzheimer’s

Research reveals immune cells target brainstem nerves, linking smell loss to early Alzheimer's, offering potential for earlier diagnosis and intervention.

Impaired spatial orientation found in older adults at risk for Alzheimer’s disease

Individuals with an increased risk for dementia due to Alzheimer's disease can have impaired spatial orientation skills.

Epigenomic erosion linked to cognitive decline in Alzheimer’s patients

Most people recognize Alzheimer's from its devastating symptoms such as memory loss, while new drugs target pathological aspects of disease manifestations, such as plaques of amyloid proteins.

New insights into early brain circuit breakdown in Alzheimer’s

One of the first parts of the brain affected by Alzheimer's disease is the entorhinal cortex - a region that plays a big role in memory, spatial navigation, and the brain's internal mapping system.

New mouse models reveal mechanisms of RP59 retinal degeneration

Retinitis pigmentosa retinal degeneration is caused by a family of hereditary mutations in nearly 100 genes that slowly lead to blindness over years or decades.

Stanford scientists make mouse skin transparent to study brain development

During childhood and adolescence, our brain goes through a lot of changes. But studying those changes in juvenile mice is challenging because scientists don't have a way to repeatedly image the same animal's neural pathways as they grow.

Routine eye exams may help detect Alzheimer’s years before symptoms appear

Within the next few years, doctors may be able to spot signs of Alzheimer's disease and other dementias using routine eye exams well before symptoms appear, a new study suggests.

Abnormal fusion protein drives childhood brain tumor through condensate formation

A study looking at the biophysical properties of an abnormal protein driving cancer cells is giving scientists new therapeutic clues for how to treat ependymoma, the third most common childhood brain tumor.

Transcutaneous vagal nerve stimulation shows promise for gastrointestinal disorders

Imbalanced autonomic function, characterized by reduced vagal activity and sympathetic dominance, is increasingly recognized in various gastrointestinal (GI) disorders.

Specialized neurons in mice influence social attention and empathy

A special set of neurons directs mice's attention to or away from their peers, depending on the situation. The Kobe University discovery has implications for finding causes for neuropsychiatric conditions such as autism spectrum disorder or schizophrenia.

Research uncovers key role of the brain's blood flow dynamics in Alzheimer’s disease

Over seven million Americans are living with Alzheimer's disease (AD) and the heartbreaking day-to-day battle with the effects of cognitive decline.

Study shows brain keeps internal body map intact after amputation

Researchers tracked brain activity before and after arm amputation and found that hand and lip maps in the cortex remained remarkably stable for up to five years. This challenges decades-old assumptions of large-scale remapping and supports the idea of a resilient internal body model.
