Melanocyte stem cells from human hair follicles that carry CD34 have the ability to turn into glial cells. The CD34+ stem cells can regenerate myelin, both on neurons and in mouse models with a genetic defect that prevents the formation of healthy myelin sheaths. The findings could have positive implications for the treatment of demyelinating diseases, such as Multiple Sclerosis.
Perception is founded on Bayesian principles, even though the brain's execution of strategies appears to be imperfect. Researchers say the view perception is an imperfect Bayesian inference can provide a middle ground between traditional and anti-Bayesian models.
Administering oxytocin blocks the enhanced motivation for drinking alcohol that fuels alcohol use disorder by blocking GABA signaling in the central nucleus of the amygdala.
A new study reports babies' brains are sensitive to different emotional tones they hear in voices. Researchers suggest maternal interactions may help to shape the same brain region adults use for emotional processing.
When parents play with their child, their brains show similar bursts of brain activity. The activity is linked to their baby's attention patterns, and not their own, researchers report.
Researchers report a father's exposure to nicotine may have lasting effects on the cognitive development of his offspring. The study reports nicotine exposure may cause epigenetic alterations in key genes within the father's sperm, affecting not only his direct children but also grandchildren.
A new study reveals receiving a hug on a day when you experience interpersonal conflict can be a buffer against negative mood and distress.
Researchers say there is a link between improved cognitive functioning in Alzheimer's disease and different seasons. The study reports those with Alzheimer's have better cognitive skills during late summer and early fall. Additionally, there was an association with seasonality and levels of Alzheimer's related proteins in the brain.
Researchers report sleep may be vital in supporting antioxidant processes. The study, which used short sleeping fruit flies, revealed sleep defends the body against oxidative stress, and oxidative stress in turn helps the sleep process.
