Diagnosis of early-stage Parkinson’s disease now possible with new method, researchers report

Cellular changes in Parkinson’s could be revealed by adapting a related technique, known as quantitative MRI (qMRI). A new method enabled researchers to look at microstructures within the part of the deep brain known as the striatum — an organ which i…

Neuronal cell type for controlling the flow of information in the brain

Researchers have identified specific cells that regulate the transmission of information between brain areas. This discovery forms the basis for the development of new treatment options for neuropsychiatric disorders which are characterized by impaired…

Whole blood exchange could offer disease-modifying therapy for Alzheimer’s disease

A novel, disease-modifying therapy for Alzheimer’s disease may involve the whole exchange of blood, which effectively decreased the formation of amyloid plaque in the brains of mice, according to a new study.

Wireless activation of targeted brain circuits in less than one second

Neuroengineers have created wireless technology to remotely activate brain circuits. Researchers showed they could control the behavior of freely moving fruit flies using magnetic signals that activated genetically engineered neurons causing the flies …

Moderate drinking linked to brain changes and cognitive decline

Consumption of seven or more units of alcohol per week is associated with higher iron levels in the brain, according to a study of almost 21,000 people. Iron accumulation in the brain has been linked with Alzheimer’s and Parkinson’s diseases and is a p…

Sentences have their own timing in the brain

Our brain links incoming speech sounds to knowledge of grammar, which is abstract in nature. But how does the brain encode abstract sentence structure? In a neuroimaging study, researchers report that the brain encodes the structure of sentences (‘the …

Could eating fruit more often keep depression at bay?

A study surveyed 428 adults and looked at the relationship between their consumption of fruit, vegetables, sweet and savoury food snacks and their psychological health. The more often people ate fruit, the lower they scored for depression and the highe…

A brain network for social attraction

How does an animal’s brain recognize other animals of its own kind? Scientists studying this process in young zebrafish have now discovered a neuronal circuit that mediates social attraction. This specialized pathway, which runs from the retina deep in…

Hidden consciousness detected with EEG predicts recovery of unresponsive patients

Using EEG to identify covert consciousness in unresponsive brain-injured patients could help predict which ones may recover, researchers have found.

Scientists pinpoint reason why women may not respond to depression treatments the same as men

Previous analyses within the nucleus accumbens showed that different genes were turned on or off in women, but not in men diagnosed with depression. These changes could have caused symptoms of depression, or alternatively, the experience of being depre…
