New imaging scan reveals a culprit in cognitive decline of Alzheimer’s

Advanced imaging technology has helped scientists confirm that the destruction of brain synapses underlies the cognitive deficits experienced by patients with Alzheimer’s disease. For many years, scientists have assumed that the loss of connections bet…

Blood samples from professional soccer players provides latest evidence that headers affect brain activity

Repetitive headers and accidental head impacts in soccer are leading to changes in blood patterns, linked to brain signalling pathways and potential alterations — the latest study to assess potential dangers of heading in soccer shows.

How long does it really take to recover from concussion?

A new study suggests that people with mild traumatic brain injuries may be more likely to have cognitive impairment, cognitive decline or both one year later, compared to people who were not injured. People with poor cognitive outcomes were also more l…

What lies behind a baby’s eyes

We give meaning to our world through the categorization of objects. When and how does this process begin? By studying the gaze of one hundred infants, scientists have demonstrated that, by the age of fourth months, babies can assign objects that they h…

Outstanding question in theoretical models of memory addressed

A research team has discovered that communication between two key memory regions in the brain determines how what we experience becomes part of what we remember, and as these regions mature, the precise ways by which they interact make us better at for…

How a protein controls the production of nerve cells in the brain

Researchers have discovered that the protein YME1L regulates the production of new nerve cells and the maintenance of neural stem cells in the adult brain. This holds great potential for regenerative treatments after brain injuries and other diseases.

Memory formation influenced by how brain networks develop during youth

In a new, rare study of direct brain recordings in children and adolescents, scientists have discovered as brains mature, the precise ways by which two key memory regions in the brain communicate make us better at forming lasting memories. The findings…

Human olfactory mucosa cell model opens a new perspective on Alzheimer’s disease

Researchers have developed and characterized a new cell model for Alzheimer’s disease that has wide utility for research and could prove useful in early diagnosis and testing of new therapies.

A microbial compound in the gut leads to anxious behaviors in mice

A new study shows how a particular molecule, produced by gut bacteria, affects brain function and promotes anxiety-like behaviors in mice.

‘Math neurons’ identified in the brain

The brain has neurons that fire specifically during certain mathematical operations. The findings indicate that some of the neurons detected are active exclusively during additions, while others are active during subtractions. They respond in the same …
