The old adage that practice makes perfect may very well be true, according to neuroscientists. Researchers found when a male zebra finch is in the presence of an attractive female and delivers its rehearsed mating call, a noradrenaline release in the basal ganglia shuts down variability in song and makes the call as perfect as it can be.
Motor learning deficits associated with autism may be the result of reduced levels of noradrenaline release in the primary motor cortex.
In times of uncertainty, noradrenaline helps us learn and adapt our behaviors, researchers report.
Microglia play a critical role in reorganizing neural connections, fighting infections, and repairing damage to neurons while we sleep.
Resveratrol, a compound found in red wine, may help to combat depression and anxiety. The compound inhibits PDE4, an enzyme induced bt excessive amounts of corticosterone, which causes depression-like symptoms in mouse models.
A new study sheds light on how the brain changes as a result of chronic stress. Selective noradrenaline release rewires connectivity patterns between different brain regions. Activity in the amygdala and networks that process sensory stimuli increased.
Glial cells and radial astrocytes might control the decision to give up swimming against the current in Zebrafish.
According to researchers, gut bacteria may regulate the neural circuits behind movement in fruit flies. Researchers say gut bacteria may play a similar role in controlling mammalian locomotion, and even movement disorders such as Parkinson's disease.
Researchers have identified a new neural mechanism that contributes to long term stress and PTSD. The study reports the mechanism is mediated by brain fluid in areas associated with stress response.
