Understanding the adolescent brain

New research from neuroscientists shows that the brains of adolescents struggling with mental-health issues may be wired differently from those of their healthy peers.

Why is drinking in moderation so difficult for some people?

Scientists have identified a specific circuit in the brain that could be targeted to treat compulsive drinking.

Obesity could affect brain development in children

New research found that obese children had a thinner pre-frontal cortex than normal weight children. The thinner cortex could be factor in the decreased executive function earlier studies observed among children with higher BMI. The new study confirmed…

Dogs process numerical quantities in similar brain region as humans

The results of a new canine numerosity study suggests that a common neural mechanism has been deeply conserved across mammalian evolution.

Why is it so difficult to make people change their minds?

It can be difficult to convince others to change their minds about a topic, sometimes even despite compelling evidence. Why? What happens in the brain?

Brain waves in mice change based on memory age

Researchers have discovered signatures in brain activity that allow them to tell old and new memories apart. The team analyzed recordings from mouse brains using a machine-leaning algorithm, which was able to accurately classify memories as recent or r…

Mothers’ and babies’ brains ‘more in tune’ when mother is happy

Mothers’ and babies’ brains can work together as a ‘mega-network’ by synchronising brain waves when they interact. The level of connectivity of the brain waves varies according to the mum’s emotional state: when mothers express more positive emotions t…

Zooming in on brain circuits allows researchers to stop seizure activity

A team of neuroscientists have found, in animal models, that they can ‘switch off’ epileptic seizures. The findings provide the first evidence that while different types of seizures start in varied areas of the brain, they all can be controlled by targ…

The effect of taking antidepressants during pregnancy

Exposure to antidepressants during pregnancy and the first weeks of life can alter sensory processing well into adulthood, according to research in mice.

Visual neurons don’t work the way scientists thought

A new survey of the activity of nearly 60,000 neurons in the mouse visual system reveals how far we have to go to understand how the brain computes. The analysis reveals that more than 90% of neurons in the visual cortex, the part of the brain that pro…
