Document Summary
Recap: total lack of consciousness: brain death, selective consciousness/selective awareness. Disorder of visual consciousness: blindsight: damage to the primary visual cortex, perception without consciousness, attribution of (cid:862)seei(cid:374)g-like a(cid:272)tio(cid:374)s(cid:863) to (cid:862)feeli(cid:374)gs(cid:863, bypassing their primary visual cortex. If you throw something to them, they will duck or catch it. Which is better: owl: late riser, energized in evening, lark: morning person, performance declines as the day goes on, neither is naturally better, research suggests you should set your schedule around which you are. Sleep disorders: sleep deprivation has many negative consequences. If you fix your sleep hygiene now, could avoid cognitive decline and dementia later. Why do we sleep: repair and restore the body and brain, repairs damaged neurons, weakening/pruning unused neuronal connections, get rid of (cid:374)euro(cid:374)al (cid:272)o(cid:374)(cid:374)e(cid:272)tio(cid:374)s (cid:449)e do(cid:374)"t use, promote muscle development. Increase athletic capabilities: why: secrete growth hormones at night, strengthen neural connections, protection during the most dangerous time of day.
