Study by UAlberta scientists explores in greater depth the effect on infant cognition of drinking fruit juice while pregnant.
Breathing propels everything we do -- so its rhythm must be carefully organized by our brain cells, right? Wrong. Every breath we take arises from a disorderly group of neurons -- each like a soloist belting out its song before uniting as a chorus to harmonize on a brand-new melody. Or, in this case, a fresh breath.
Excessive weight around our middle gives our brain's resident immune cells heavy exposure to a signal that turns them against us, setting in motion a crescendo of inflammation that damages cognition, scientists say.
Researchers know that the protein tau develops into tangles in the brains of people with Alzheimer's disease. But until now they have struggled to understand what factors make you more or less likely to develop these tangles. In a preliminary study released today that will be presented at the American Academy of Neurology's 72nd Annual Meeting in Toronto, Canada, April 25 to May 1, 2020, researchers say that they have identified gene variants that are associated.
Within hours of birth, a baby's gaze is drawn to faces. Now, brain scans of newborns reveal the neurobiology underlying this behavior, showing that as young as six days old a baby's brain appears hardwired for the specialized tasks of seeing faces and seeing places.
A blood test that may eventually be done in a doctor's office can swiftly reveal if a patient with memory issues has Alzheimer's disease or mild cognitive impairment and can also distinguish both conditions from frontotemporal dementia.
When crossing the street, which way do you first turn your head to check for oncoming traffic? This decision depends on the context of where you are. A group of scientists at Columbia's Zuckerman Institute has been studying how animals use context when making decisions. And now, their latest findings have tied this ability to an unexpected brain region in mice, previously thought to primarily guide and plan movement.
Each day, humans and animals rely on habits to complete routine tasks such as eating. As new habits are formed, this enables us to do things automatically without thinking. As the brain starts to develop a new habit, in as little as a half a second, one region of the brain, the dorsolateral striatum, experiences a short burst in activity, which increases as the habit becomes stronger. A Dartmouth study demonstrates how habits can be controlled depending on how active the dorsolateral striatum is.
Different learning difficulties do not correspond to specific regions of the brain, as previously thought, say researchers at the University of Cambridge. Instead poor connectivity between 'hubs' within the brain is much more strongly related to children's difficulties.
People with higher obsessive-compulsive symptoms may place less trust in their past experience, leading to increased uncertainty, indecisiveness, and exploratory behaviors, according to new research presented in PLOS Computational Biology by Isaac Fradkin of The Hebrew University of Jerusalem, Israel, and colleagues.
