Document Summary
Introduction, overview of cns organization, anatomy, development and evolution. The 10 % myth: the claim that humans only use 10% of their brain has unknown origins, but both marie- Jean-pierre flourens (1974-1867) and karl lashley (1890-1958) performed experiments that involved damaging or removing large portion of animal brains. After, the animals were observed and often animals could still perform basic functions. These results led others to overinterpretation and exaggeration that the animals used only 10% of their brains, later being generalized to humans. Experimental neuropsychology is also called cognitive neuropsychology/cognitive neuroscience. There are also ancient skulls that have been surgically excised or cut open (maybe for therapeutic value). The mind-body problem: rene descartes (1596-1650) presented a reflexive theory of the control of behaviour which he described the flow of animals spirits through valvules within nervous tissue filaments. This theory accounted for reflexive behaviours by describing how external stimuli would move the skin etc.
