Finding Turns Neuroanatomy On Its Head

Harvard researchers present new view of myelin.

Harvard neuroscientists have made a discovery that turns 160 years of neuroanatomy on its head.

Myelin, the electrical insulating material long known to be essential for the fast transmission of impulses along the axons of nerve cells, is not as ubiquitous as thought, according to a new work lead by Professor Paola Arlotta of the Harvard Stem Cell Institute (HSCI) and the University’s Department of Stem Cell and Regenerative Biology, in collaboration with Professor Jeff Lichtman, of Harvard’s Department of Molecular and Cellular Biology.

Boost Your Brain: Harnessing Neurogenesis | Reality Sandwich

Sam Gandy • 4 months ago • 2 Comments

“Neurogenesis is the birth of new neurons from neural stem or progenitor cells in the brain. This takes place in the brain over the course of the adult lifespan, declining with age, but there are a number of behavioural, environmental, pharmacological and biochemical factors that affect this process, many of which we have considerable power to influence.” 7 more words
