To learn is to change.
Education is a process that changes the learner.
The Nature article suggests that this is biological confirmation of the importance of education and contradicts the previous dogma that the number of active brains cells is essentially fixed early in life. Similar tests were performed in the 1970s by psychologist William Greenough at the University of Illinois and they reached this same conclusion. The Emperor's New Mind describes the relevance of synaptic firing in the phenomenon of brain plasticity. The interconnections between neurons are not in fact fixed but are changing all the time. I am referring to the synaptic junctions where the communication between different neurons actually takes place.
