Document Summary

Social neuroscience: the scientific study of how biological and social processes interact. Phineas gage: railroad construction foreman in 1848. Used to be a very respectable and well-liked person. Became intolerable and used a lot of profanity no longer himself. Limitations within genetics: genes are predispositions, the statistics of genes can. Genetics: genes hold code to making proteins and can correlate genotype with psychological traits like personality, etc. be tricky, cannot be manipulated in humans. Lesions: observe psychological differences when certain brain areas are not functioning and genetic lesions current stimulation, temporarily hyperpolarizes (inhibits) and depolarizes neurons. Brain imaging: mri (taking still photos of brain, good for seeing brain structure), fmri. Ex: in humans, accidental lesions and temporary lesions but in animals, surgical. Temporary lesions: transcranial magnetic stimulation and transcranial direct (functional, measures blood flow to areas of the brain, good for knowing where and when), eeg ((cid:373)easures ele(cid:272)tri(cid:272)al a(cid:272)ti(cid:448)it(cid:455) throughout (cid:271)rai(cid:374), takes (cid:373)easure(cid:373)e(cid:374)ts rapidl(cid:455), do(cid:374)"t k(cid:374)o(cid:449) (cid:449)here signal comes from)
