Re: 迴路(synapses)的增長-培育資優的第一步
FETAL BRAIN & COGNITIVE DEVELOPMENT by R. Joseph, Ph.D.
"As the brain is formed, billions of excess neurons and dendrites are produced which in turn form innumerable random interconnections (Rakic, Bourgeois, Echenhoff, Zaecevic & Goldman-Rakic, 1986). Over the course of late fetal development and over the first several years of life, billions of these excess dendrites, synapses, and neurons are absorbed, discarded and die (Joseph, 1982, 1998). This process of elimination and programmed cell death is also under environmental control (e.g., Casagrande & Joseph, 1978. 1980; Joseph, 1999). That is, the maturing, developing brain sheds innumerable excess neurons, dendrites, and random synaptic interconnections, as a function of experience, or lack thereof. "
“through repetitive auditory stimulation (e.g. Babyplus), or lack thereof, specific midbrain neural networks and pathways are molded, and these, in turn, selectively respond to the stimuli which shaped them (Moore & Aitkin, 1975; Moore & Irvine, 1981)."
