Fast-acting immune cells provide powerful protection against stroke

CD8+ regulatory-like T cells reach the brain within 24 hours after stroke onset, where they release molecules that provide direct neuroprotective effects, as well as limit inflammation and secondary brain damage.

Sound of music: Ultrasound exposure improves depressive behavior in rodents

It is well known that whole-body exposure to high frequency ultrasound increases brain activity in humans. However, little is known about its impact and associated mechanisms on emotional states like depression. Now researchers have recently demonstrat…

Children who lack sleep may experience detrimental impact on brain and cognitive development that persists over time

Elementary school-age children who get less than nine hours of sleep per night have significant differences in certain brain regions responsible for memory, intelligence and well-being compared to those who get the recommended nine to 12 hours of sleep…

Advanced imaging reveals mired migration of neurons in Rett syndrome lab models

Using organoids to model early development, researchers used an emerging microscopy technology to see that new neurons struggled to reach their developmental destination.

Pinpointing consciousness in animal brain using mouse ‘brain map’

Science may be one step closer to understanding where consciousness resides in the brain. A new study shows the importance of certain types of neural connections in identifying consciousness.

Common viruses may be triggering the onset of Alzheimer’s disease

Two common viruses lie dormant in neurons — herpes simplex virus (HSV), and varicella zoster virus (VZV). Lab models of the human brain show that activation or re-infection of VZV can trigger neuroinflammation and wake up HSV, leading to accumulation …

Taking your time makes a difference

Researchers find that stem cells in the developing brain of modern humans take longer to divide and make fewer errors when distributing their chromosomes to their daughter cells, compared to those of Neanderthals.

COVID-19 infection in crucial brain regions may lead to accelerated brain aging

A new study reviews the emerging insights and evidence that suggest COVID-19 infections may have both short- and long-term neurological effects. Major findings include that COVID-19 infections may predispose individuals to developing irreversible neuro…

Some types of stress could be good for brain functioning

It may feel like an anvil hanging over your head, but that looming deadline stressing you out at work may actually be beneficial for your brain, according to new research. The study found that low to moderate levels of stress can help individuals devel…

Specialized brain regions recognize vocal cues that don’t involve speech

New research finds that specific parts of the brain recognize complex cues in human vocal sounds that do not involve speech, such as crying, coughing or gasping. Insights into the organization of the brain voice-recognition system will enable researche…
