Lewy body disease can be detected before symptoms

Lewy body disease is the second most common neurodegenerative disease after Alzheimer’s disease. A research group has now shown that the disease can be detected before symptoms appear, using a spinal fluid test. Researchers also demonstrate that reduce…

Fear is in the eye of the beholder

Averting our eyes from things that scare us may be due to a specific cluster of neurons in a visual region of the brain, according to new research. Researchers found that in fruit fly brains, these neurons release a chemical called tachykinin which app…

Boosting certain brain cells diminished hypersensitivity in Fragile X mice

Study suggests modulating the activity of certain neurons could be an effective approach to restoring circuit function.

Controlled cruelty: New study finds aggression can arise from successful self-control

A new study has found that aggression is not always the product of poor self-control but, instead, often can be the product of successful self-control in order to inflict greater retribution.

High-quality sleep promotes resilience to depression and anxiety

Research has shown quality sleep can help bolster resilience to depression and anxiety.

Artificially grown ‘mini-brains’ without animal components bring opportunities for neuroscience

Researchers developed a method to produce artificially grown miniature brains — called human brain organoids — free of animal cells that could greatly improve the way neurodegenerative conditions are studied and, eventually, treated. The work offers …

Social isolation linked to lower brain volume

Older people who have little social contact with others may be more likely to have loss of overall brain volume, and in areas of the brain affected by dementia, than people with more frequent social contact, according to a new study.

Neurons that track, regulate blood-sugar levels are found

New research has discovered neurons within the brain which detect and respond to changes in the level of sugar within the bloodstream. Understanding how this blood-sugar detection system works and how these neurocircuits operate would give researchers …

Preying on hungry, anxious worms

Scientists find that the ‘feel good’ brain chemical dopamine regulates anxious worm behavior in the presence of nipping predators. The findings illuminate how this dopamine-regulated brain pathway may be related to anxiety and could provide insight int…

Inflammation hotspots in MS spill over to damage grey matter

A study in mice suggests that inflammation in the brain’s barrier, the meninges, may spill over into grey matter and cause changes that can contribute to progressive multiple sclerosis (MS).
