PSYB57H3 Chapter 2: Cognitive Neuroscience
Document Summary
Chapter 2: cognitive neuroscience: the brain as the organ of the mind, the chapter will introduce several ways of investigating the relationship between the brain and behaviour. Localization of function: the idea that there is a direct correspondence between specific cognitive function and specific parts of the brain. If functions were localized in the cortex, then the affect of ablation should depend on the area destroyed; however, this was not what his observations showed. Franz and his student karl lashley (1890-1958) studied the effects of ablation of the frontal lobes in rats. Law of mass action: learning and memory depend on the total mass of brain tissue remaining rather than the properties of individual cells. In other words, the brain has no causal role in determining behaviour - it is merely a by-product of brain processes: t. h. Found its purest expression in the work of g. t.
