BIO SCI N113L Lecture Notes - Lecture 3: Jean Pierre Flourens, Gustav Fritsch, Brenda Milner
Document Summary
Define principles of mass action, equipotentiality, and localization of brain function. Mass action: holistic view; cognitive functions result from coordinated activity of the brain as a whole. Equipotentiality: incomplete lesions produced deficits that could be ameliorated by time or retraining; all regions of brain are sufficient for problem solving and memory. Localization of brain function: different functions correspond to different parts of the brain. Indicate whether a scientific discovery supports the localization of function view or holistic view. Phrenology: mind was composed of a set of different mental faculties and were represented in a specific area of the brain: reflected in skull bone, localization of function. Jean pierre flourens tested phrenology experimentally through lesions and found localization of function in some aspects but not all. Holistic view: cognitive faculties result from coordinated activity of the brain as a whole. Paul broca: supported localization: tantan: couldn"t say anything but tan , large lesion in ventral region of frontal lobe.
