Neuroscientists illuminate how brain cells ‘navigate’ in the light and dark

Researchers have discovered how individual and networks of cells in an area of the brain called the retrosplenial cortex encode this angular head motion in mice to enable navigation both during the day and at night.

Older-looking brains linked to lower birth weight and genes

In brain scans of almost 1500 people throughout Europe, researchers found that people with ‘older-looking’ brains had both lower birth weight and genes for smaller brains, compared with those with normal aging brains. Both these factors are present ear…

As we develop, the brain connects lessons learned differently

A new study of brain activity patterns in people doing a memory task finds that the way we make inferences — finding hidden connections between different experiences — changes dramatically as we age. The study’s findings might one day lead to persona…

Evidence dyslexia affects children’s visual processing beyond just reading

First study combining multiple new methods to understand visual processing and brain activity in dyslexia could improve understanding of which brain processes are affected by the condition, and potentially improve interventions.

Researchers discover new insights about tau proteins in people living with ALS

Investigators found elevated levels of tau and a phosphorylated form of the tau protein in brain tissue from deceased people who had amyotrophic lateral sclerosis (ALS) and carried a mutation in the C9orf72 gene. The team also identified new genetic mu…

A key brain region responds to faces similarly in infants and adults

In a functional magnetic resonance imaging study of babies ranging in age from two to nine months, researchers have found regions of the infant visual cortex that show strong preferences for either faces, bodies, or scenes, just as they do in adults.

Anxiety cues found in the brain despite safe environment

Researchers used a virtual-reality environment to understand the impact anxiety has on the brain and how brain regions interact with one another to shape behavior.

Vascular defects appear to underlie the progression of Parkinson’s disease

In an unexpected discovery, researchers have identified what appears to be a significant vascular defect in patients with moderately severe Parkinson’s disease. The finding could help explain an earlier outcome of the same study, in which the drug nilo…

New optical technology spotlights how memories move in mouse brains during sleep

Scientists have used mouse brains to demonstrate a new neural-optic system to manipulate memories. The technique hinders nerve activity — known as long-term potentiation or LTP — which would otherwise consolidate memory during sleep. The research tea…

Surprising findings on how salt affects blood flow in the brain

Researchers reveal surprising new information about the relationship between neuron activity and blood flow deep in the brain, as well as how the brain is affected by salt consumption.
