Unique brain changes in people with Huntington’s disease

The part of the brain that selectively degenerates in people with Huntington’s disease (HD), called the striatum, is almost entirely destroyed in the late stages of the disease. Brain samples from mutant HD gene positive individuals who had not yet dev…

The night gardeners: Immune cells rewire, repair brain while we sleep

Science tells us that a lot of good things happen in our brains while we sleep — learning and memories are consolidated and waste is removed, among other things. New research shows for the first time that important immune cells called microglia — whi…

Make some noise: How background noise affects brain activity

Have you ever found it difficult to focus on a task due to background noise? Scientists are studying just how these sounds impact our brain activity — and what that impact means for designing neurotechnology.

Work and family demands may impact women’s heart health

A new Brazilian study has found that stress arising from balancing work and family life can detrimentally affect women’s cardiovascular health.

A new discovery: How our memories stabilize while we sleep

Scientists have shown that delta waves emitted while we sleep are not generalized periods of silence during which the cortex rests, as has been described for decades in the scientific literature. Instead, they isolate assemblies of neurons that play an…

Monkeys demonstrate more cognitive flexibility than humans

In a recent study, researchers conclude that in certain tasks, capuchin and rhesus monkeys are more cognitively flexible than humans.

New clinical research offers possibility of future rehabilitation for patients in minimally conscious or vegetative state

Non-invasive brain stimulation is to be trialled for the first time alongside advanced brain imaging techniques in patients who are minimally conscious or in a vegetative state.

Male and female mice have different brain cells

Scientists discover that a brain region known to control sex and violence contains rare cell types that differ in male versus female mice.

BARseq builds a better brain map

A brain mapping technique called BARseq is capable of mapping thousands of neurons in a single mouse, at single neuron resolution, while also detailing which neuron expresses what genes. It could be a game-changer for how neuroscientists look at brains.

Cultivating joy through mindfulness: An antidote to opioid misuse, the disease of despair

New research shows that a specific mind-body therapy, Mindfulness-Oriented Recovery Enhancement (MORE), increases the brain’s response to natural, healthy rewards while also decreasing the brain’s response to opioid-related cues.
