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.

A group of four neuroscientists from Denmark, Sweden, UK, and USA who discovered a key mechanism that causes migraine that led to revolutionary new treatments receive The Brain Prize, the world’s most valuable prize in neuroscience.
Four decades of research paved the way for the development of entirely new classes of migraine-specific drugs which are now on the market and are already radically improving the lives of sufferers.
The Brain Prize is awarded annually by the Lundbeck Foundation and is worth DKK 10 (approximately £1.1m, $1.5m, €1.3m).
The Brain Prize will be awarded at a ceremony in Copenhagen on 25 October 2021, presided over by His Royal Highness, The Crown Prince of Denmark.
The article was published in MacLean’s in October 2020, in a special section on “Understanding Neurological Conditions”, and re-published in the December 2020 edition of Chatelaine, in a special section on “Managing Chronic Conditions”.
CAN Trainee research features are a new opportunity for Canadian neuroscience trainees to showcase their research through short video features. We aim to make this a weekly feature and to share on our website and social media accounts, so please consider submitting a proposal to us!
This week’s feature is Nuria Daviu, a researcher in the laboratory of Dr. Jaideep Bains, at the Hotchkiss Brain Institute.
