Researchers are reporting a novel technique for tracing the activity of individual nerve fibers known as axons, and determining how neurons communicate. The team used this technique to uncover details about how the brain responds to light signals received by the retina in mice.
Read moreThe human brain is about three times the size of the brains of great apes. This has to do, among other things, with the evolution of novel brain structures that enabled complex behaviors such as language and tool production. A study by anthropologists now shows that changes in the brain occurred independent of evolutionary rearrangements of the braincase.
Read moreA psychologist is reporting that hope increases in therapy and is a trait that predicts resilience and recovery from anxiety disorders, an important mechanism for therapists to restore in patients to move them forward toward recovery.
Read moreThe new function of unused cortical regions is not necessarily determined by the function of nearby cortical regions, according to new research in adults born without one hand.
Read moreUsing advanced imaging, researchers have uncovered new information regarding traumatic microbleeds, which appear as small, dark lesions on MRI scans after head injury but are typically too small to be detected on CT scans. The findings published in Brain suggest that traumatic microbleeds are a form of injury to brain blood vessels and may predict worse outcomes. The study was conducted in part by scientists at the National Institute of Neurological Disorders and Stroke (NINDS), part of the National Institutes of Health.
Read morePatients with depression, anxiety or stress are more likely to drop out of cardiac rehabilitation, reports a new study.
Read moreDepression affects women nearly twice as much as men, but unraveling the brain's blueprint that regulates this behavior, let alone identifying specific molecular differences between sexes, has proven difficult. Researchers, however, have found and flipped a switch in the brain, revealing a single circuit in mice that activates during stress and is controlled by testosterone.
Read moreNew brain imaging research debunks a controversial theory about dyslexia that can impact how it is sometimes treated. The cerebellum, a brain structure traditionally considered to be involved in motor function, has been implicated in the reading disability, developmental dyslexia, however, this 'cerebellar deficit hypothesis' has always been controversial. The new research shows that the cerebellum is not engaged during reading in typical readers and does not differ in children who have dyslexia.
Read moreBiological siblings of people with gambling disorder also display markers of increased impulsivity and risk-taking, according to a new psychology study. The findings suggest people with gambling disorder — a psychiatric term for serious gambling problems — may have pre-existing genetic vulnerabilities to the illness.
Read moreScientists found a calcium channel expressed in astrocytes in the brain to be a highly sensitive target for LILFU-induced neuronal activity in the motor cortex, such as tail movement.
