Document Summary

Cognitive neuroscience: trying to figure out the link between cognition and the brain. Wer(cid:374)i(cid:272)ke"s area is i(cid:374)(cid:448)ol(cid:448)ed i(cid:374) la(cid:374)guage (cid:272)o(cid:373)prehe(cid:374)sio(cid:374) All regions ha(cid:448)e differe(cid:374)t fu(cid:374)(cid:272)tio(cid:374)s (cid:271)ut they are(cid:374)"t i(cid:374)depe(cid:374)de(cid:374)t, they tra(cid:374)s(cid:373)it information to each other. If wer(cid:374)i(cid:272)ke"s area (cid:449)as da(cid:373)aged, it (cid:449)ould se(cid:374)d i(cid:374)(cid:272)orre(cid:272)t i(cid:374)for(cid:373)atio(cid:374) to bro(cid:272)a"s area (cid:449)hi(cid:272)h (cid:449)ould (cid:272)o(cid:373)pro(cid:373)ise the fu(cid:374)(cid:272)tio(cid:374)i(cid:374)g of bro(cid:272)a"s area. They are dependent on each other to function well. By sending each other information these different regions are working together so that you per(cid:272)ei(cid:448)e as o(cid:374)e.

Methods are categorized by spatial and temporal resolution. Spatial: where things are happening in the brain. High spatial resolution: when you can tell exactly where things are occurring. Poor spatial resolution: hard to tell where exactly things are happening. High temporal resolution: you can tell exactly when something occurred.
