Document Summary
Asomatognosia- a deficiency in the awareness of one"s own body. Three evidence points for natural selection: geological records, homologous structures, artificial selection. Heritability estimate: tells the contribution of genetic differences to phenotypic difference among the participants in a study. Oligodendrocytes- extensions that wrap around other cns cells; myelin sheath. Schwann cells- extensions that wrap around other pns cells; myelin sheath. Na+ is kept outside neuron because channels to get into cell are closed. K+ is kept inside because of the negative resting potential (electrostatic pressure) Goes up to ~50 saltatory conduction: conduction using the nodes of ravier dendritic spines: nodules of various shapes that are located on the surfaces of many dendrites synaptic vesicles: vesicles with neurotransmitters. Unconventional neurotransmitters: soluble gases: nitric oxide, carbon monoxide fmri: requires bold signals. Tms: transcranial magnetic stimulation; turn off parts of your cortex. Scl/scr: skin conductance level/response; electric changes in skin. Bregma: where two major sutures of skull come together.
