A CERVO research centre team demonstrates the role of light and calcium ions in neural stem cell activation in adulthood
It has long been believed that neurons in the human brain develop only during the period from embryogenesis to adolescence. It is now known that in some areas of the brain, neural stem cells remain and give rise to neurons even in adults. “These stem cells can remain quiescent for long periods of time and we still know very little about the mechanisms that make them go from a quiescent state to an activated state,” says Armen Saghatelyan, from the Université Laval and the CERVO Brain Research Centre.

Social deficits attract so much attention in the study of autism spectrum disorder, it’s easy to forget there are motor learning deficits during early childhood as well. For autistic kids hoping to throw a ball around the schoolyard and connect with classmates, these physical skill differences can isolate a child further.
In a new study published in Nature Neuroscience researchers from the University of Ottawa’s Faculty of Medicine have closed in on the neurological underpinnings of the motor learning delay. Dr. Simon Chen’s lab in the Department of Cellular and Molecular Medicine used a mouse model of autism to demonstrate a shortage in the amount of the neurotransmitter noradrenaline being released into the brain’s primary motor cortex.
Dr. Chen’s lab identified the problem originating some distance away in an area of the hindbrain called the locus coeruleus, which is known as a center of motivation, alertness, and attention.
