Mind, Brain, and Education (MBE)



“Perhaps one of the biggest shifts in thinking about the brain occurred with the eradication of the dogmatic belief that at birth humans are endowed with our full count of neurons, and that no new neurons produced in adulthood. Historically, research on the production of new brain cells into adulthood, i.e. adult neurogenesis, had been recognized for years in both rat hippocampal dentate gyurs (Altman & Das, 1965; Altman &Das,1967) and specialized regions of the bird brain (Nottebohm, 1981). Unfortunately, the belief that the bird brain or rodent brain needed to produce new neurons due to its size helped maintain the idea that adult humans and higher mammals did not produce new neurons in adulthood (Rakic, 1985). It wasn’t until 1999 when Elizabeth Gould published an article in the well-respected journal, Science, that this dogma was shattered forever (Gould, Reeves, Graziano & Gross, 1999). Gould demonstrated not only that adult neurogenesis occurred in the monkey brain, but that it occurred in the cortex, the region of the brain attributed to higher conscious processes, as well as the hippocampus. To further advance this idea that new neurons continue to be produced into adulthood, researchers at UC San Diego published findings of adult neurogenesis in the human hippocampus (Eriksson, Perfilieva, Bjork-Eriksson, Laborn, Nordborg, Peterson & Gage,361998). This paradigm shift changed the way we looked at neural circuitry and has found relevant connections to our understanding in relation to education.” Retrieved 12/2/2013 from Abigal Larrison Dissertation.
