Researchers created a form of artificial vision for a blind woman with the aid of a brain implant position in the visual cortex. The results pave the way for the creation of visual brain prosthetics to help the blind to regain sight.
MicroRNA-132 regulates neurogenesis in the hippocampus, according to both mouse and human tissue studies. Restoring levels of microRNA-132 in mouse models of Alzheimer's disease reduces neurogenetic deficits and restores cognitive abilities, researchers say.
Study identifies a cell-type specific brain circuit associated with curiosity and novelty-seeking behaviors.
Coercion to perform detrimental actions against others reduces empathy and guilt, a new study reports. The findings may explain why people are able to commit immoral acts that go against their ethical stance when coerced.
In late-stage multiple sclerosis, inflammatory cells no longer enter the brain via the bloodstream, but instead the cells arise in memory from local memory cells inside the brain. The findings suggest during the late phases of multiple sclerosis, the disease is occurring entirely inside the brain.
Rats show altruistic behavior and avoid harming other rats. Researchers report harm aversion is deeply engrained in our biology. The findings pave the way to increasing harm aversion in those with empathy disorders, such as psychopathy and sociopathy.
Reducing activity in the anterior cingulate decreases empathetic responses in rats. The data suggests an observer shares the emotions of others as it enables them to prepare for danger.
Restless REM sleep disrupts the adjustment of memory traces during sleep. This may increase negative emotions associated with mental health disorders.
For some, insomnia may be caused by failing to neutralize emotional distress. Researchers speculate the sleep disorder could be caused by brain circuits that regulate emotion.
Study reports the anterior cingulate cortex of rats contain mirror neurons that respond to pain experienced by and observations of others.
A new study reveals gene therapy in combination with neurosurgery can help to improve the rate of survival and promote regeneration of nerve fibers.
Researchers have identified five different subtypes of the sleep disorder insomnia, including difficulty falling asleep and early morning awakening. The study reports insomnia subtypes may be identified by examining personality traits of sufferers.
