Document Summary

Brain size and iq r= 0. 33 correlaion more to iq than brain size. Genius comes in all sizes of brain. His parietal lobes (linked with math abiliies) is 15% larger than average, frontal lobes have more wrinkles than average and his. Correlaion with speed and iq; higher iq faster at processing informaion. Reacion ime, how long for reacion ime. Higher iq have shorter and faster reacion ime. Perceptual speed; how much ime ater simulus to answer a simple quesion correctly: for example, which of the two objects is bigger. Nerve conducion velocity (ncv) how fast neurons conduct higher iq (faster) Brain waves (high iq faster waves from lash of light) Frontal lobes acivated in iq test and luid intelligent test acive more, muliple brain areas interact with each other for brain funcion and iq. Glucose consumpion for energy, more acive more glucose: less glucose with higher iq brain works more eiciently using less glucose.
