Neuroscientists use deep learning model to simulate brain topography

A more accurate model of the visual system may help neuroscientists and clinicians develop better treatments for alexia, prosopagnosia and agnosia.

Study finds high levels of depression, anxiety among disabled people during COVID-19 pandemic

A new study confirms what many in the disabled community already know: People with disabilities have been experiencing high levels of depression and anxiety during the COVID-19 pandemic.

Study confirms site of brain region responsible for making sure people say words as intended

A region crossing the folded surface of the top of the brain, called the dorsal precentral gyrus, plays an essential role in how people use the sound of their voices to control how they want the words to sound, a new study shows.

Scientists test promising biosensor aimed for use in brain

Scientists have successfully tested in the lab a tiny biosensor they developed that can detect biomarkers tied to traumatic brain injuries.

Mechanism revealed behind loss of smell with COVID-19

Researchers have discovered a mechanism that may explain why COVID-19 patients lose their sense of smell, as well as having implications for long COVID.

Different autism risk genes, same effects on brain development

Researchers have found that three different autism risk genes actually affect similar aspects of neuron development and the same neuron types, although each gene acted through unique molecular mechanisms. Additionally, a person’s specific genomic backg…

Greater body fat a risk factor for reduced thinking and memory ability

A new study has found that greater body fat is a risk factor for reduced cognitive function, such as processing speed, in adults. Even when the researchers took cardiovascular risk factors (such as diabetes or high blood pressure) or vascular brain inj…

Instability of brain activity during sleep and anesthesia underlies the pathobiology of Alzheimer’s disease, study finds

A new study revealed a pathological brain activity that precedes the onset of Alzheimer’s first symptoms by many years: increased activity in the hippocampus during anesthesia and sleep, resulting from failure in the mechanism that stabilizes the neura…

Growth charts for the brain help to explain mental illness

Researchers have developed a set of growth charts for the brain. These ‘brain charts’ provide reference models for brain development and ageing across the entire human lifespan, based on a very large data set. These models can be used to make personali…

Finding structure in the brain’s static

Researchers found that a monkey’s state of attentiveness may be encoded in the shapes and speeds of slow electrical waves that course over the surface of the brain. Like a surfer that avoids smooth water and favors more active waves, the brain uses fas…
