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 provides insight into the behavioral function of dopamine signaling in the striatum.
Study identifies a cell-type specific brain circuit associated with curiosity and novelty-seeking behaviors.
A new study reveals gene therapy in combination with neurosurgery can help to improve the rate of survival and promote regeneration of nerve fibers.
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.
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.
Researchers have discovered how the nature of T cells help protect the brain from viruses. The findings shed light on the role the immune system plays in a number of neurodegenerative disorders.
Researchers have released a new open-access data set recorded from the visual cortex of macaque monkeys during resting state.
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.
