PSYB65H3 Chapter Notes - Chapter 2: Frontal Lobe Injury, Somatic Nervous System, Autonomic Nervous System
Document Summary
Increases in relative brain size are associated with increases in behavioral complexity and mental capacity: one obvious difference is human language, a capacity that requires significant brainpower and is fundamental to understanding human brain organization. He concludes that the human brain has optimized its overall size, the size and number of neurons, the number and length of connections, and energy consumption. Changing any of these features would compromise the others and neutralize any performance improvements. Epigenetics: studies differences in gene expression related to environment and experience. Phenotypic plasticity: the i(cid:374)di(cid:448)idual(cid:859)s (cid:272)apa(cid:272)it(cid:455) to de(cid:448)elop i(cid:374)to (cid:373)ore tha(cid:374) o(cid:374)e phe(cid:374)ot(cid:455)pe characteristics that can be seen or measured. Neuroplasticity: the (cid:374)er(cid:448)ous s(cid:455)ste(cid:373)(cid:859)s pote(cid:374)tial for ph(cid:455)si(cid:272)al or (cid:272)he(cid:373)i(cid:272)al (cid:272)ha(cid:374)ge that e(cid:374)ha(cid:374)(cid:272)es its adaptability to environmental change and its ability to compensate for injury. Autonomic nervous system (ans): part of the pns that regulates the functioning of internal organs and glands. Afferent: conducting toward a central nervous system structure.
