Document Summary
Intro to neuropsych (cont"d): origins of the human brain and. Origins of the human brain and behavior (50:00) Graph that illustrates the relative time of origin of various closely related groups. Humanlike ancestors that diverged from the ape lineage. Brain similarities and differences in humans and animals provide insight to brain-behavior relationships. Genetic basis of behavior can be studied in animals with short lifespans (i. e. fruit flies - also very short generation time) Uses cross species comparisons to understand basic brain function for a given behavior. Rat: brain very much like human"s; cortical function is similar to human"s. Slugs: used in studying how neurons interconnect to produce behaviour because their ns is relatively simple. Fruit flies: used for studying genetic basis of behaviour because many generations of flies with ns alterations can be bred quickly. Genes: functional units that control the transmission and expression of traits from one generation to the next.
