Neuroscientists Transplant Human Neurons Into a Mouse Brain

Posted by in categories: biotech/medical, neuroscience

The brain cortex, the outside layer of our brain often referred to as grey matter, is one of the most complex structures found in living organisms. It gives us the advanced cognitive abilities that distinguish us from other animals.

Neuroscientist Professor Pierre Vanderhaeghen (VIB-KU Leuven, Université libre de Bruxelles) explains what makes the human brain so unique: “One remarkable feature of human neurons is their unusually long development. Neural circuits take years to reach full maturity in humans, but only a few weeks in mice or some months in monkeys.”

“This long period of maturation allows much more time for the modulation of brain cells and circuits, which allows us to learn efficiently for an extended period up until late adolescence. It’s a very important and unique feature for our species, but what lies at its origin remains a mystery.”
