Document Summary

Cerebral cortex: heavily folded outer layer of brain tissue composed of neurons. Behavior (eibl-eibesfeldt): patterns in time (ex. movement, memory: de la mettrie: thought is produced by brain. Innate vs. learned: fixed vs. flexible ways of responding. Supported evolutionary theories of wallace & darwin (natural selection- species evolve) Genetic mutation adaptive trait (cid:4612)chances of survival trait passed to offspring. Since all animal species are related, their behavior, neurons & brains must be related too. Facial expressions in man & animals are similar- study simpler animals to understand humans. Epigenetics: study of differences in gene expression related to environment & experience. Nerve net: simple ns, organized as a net with no brain; sensory & motor neurons (older phyla) Segmented nerve trunk: bilaterally symmetrical organization, similar series of muscular segments. Ganglia: structures that resemble & function somewhat like a brain (encephalization if found in the head)
