Depression: Dysfunction of neurons in the amygdala may be behind negative perceptions of the environment

One of the characteristics of depression is a tendency to perceive sensory stimuli and everyday situations in an excessively negative way. But the mechanisms underpinning this ‘negativity bias,’ which can fuel the development of depressive symptoms, ha…

Could a new medical approach fix faulty genes before birth?

A new biomedical tool successfully delivers genetic material to edit faulty genes in developing fetal mouse brain cells. This might stop disease progression of genetic-based neurodevelopmental conditions before birth.

New formation of neurons from stem cell niche disrupted after stroke

Researchers studied what happens immediately after a stroke in the stem cell niche known as the subventricular zone, using a mouse model. This revealed a mechanism that results in fewer newborn neurons from the stem cell niche surviving after stroke, t…

Gene named for mythical Irish land could aid muscle function after traumatic nerve injuries

Researchers describe how a gene called NANOG can improve the regrowth of damaged nerves after traumatic nerve injuries, like those sustained in motor vehicle accidents or gunshot wounds.

Chronic pain can be predicted within three days of an injury

After only one to three days of a whiplash injury, scientists can predict which patients will develop chronic pain based on the extent of cross ‘talk’ between two regions of the brain, and the person’s anxiety level after the injury, according to a new…

Study of chick peeps could improve understanding of animal emotions

Understanding animal emotions has been a long-running question at the forefront of welfare studies, but a new study may hold the key to decoding the chatter. The answer involves two baby chickens and a mirror.

‘Human mini-brains’ reveal autism biology and potential treatments

By creating personalized brain ‘organoids’ in the lab, scientists showed how microRNAs impact brain development, and demonstrate how one drug can reverse critical cellular signs of autism.

Live well, think well: Research shows healthy habits tied to brain health

In middle-aged people, having risk factors like blood pressure, blood sugar and cholesterol that are not well-controlled combined with not following certain healthy habits including exercise, diet and sleep, are linked to a higher risk of stroke, demen…

Could poor sleep in middle age speed up brain aging?

People in early middle age who have poor sleep quality, including having difficulty falling or staying asleep, have more signs of poor brain health in late middle age, according to a new study. The study does not prove that poor sleep accelerates brain…

Scanning, scrolling, and swiping: New research uncovers why our brains are effective at quickly processing short messages

A team of linguistics and psychology researchers has discovered that when a brief sentence is flashed, our brains detect its basic linguistic structure extremely quickly — in roughly 150 milliseconds, or about the speed of a blink of an eye.
