eval strength case study localisation

phineas gage

what happened to phineas gage and how does this relate to localisation

a pipe went through his head causing a personality shift from kind to aggressive due to damage to the ara controlling reasoning

localisation strength scientific research

peterson et al used brain scanning techniques to identify that wernickes and brocas area were active during speaking and listening tasks respectively

localisation weakness

only a small percentage of modern scientists agree with the idea of localisation in language and advances in brain scanning suggest that brain function is more holistic

lateralisation supporting study

fink et al used PET scans to identify which hemisphere was more dominant in visual processing tasks.when asked to look at the image as a whole R when asked to look at finer details L

strength of sperrys research

it has prompted conversation about the degree of communication between the two hemispheres

example of conversation about the degree of communication between the hemispheres

some say that the hemispheres are functionally different and represent a form of duality in the brain while others say that they work together to make a holistic system

methodological weakness sperry

only 11 participants its a lab study confounding variables of individual differences

supporting study for plasticity

elbert et al found that the somatosensory cortex in stringed musicians brains were larger than normal due to the constant movement of the left hand when playing the violin leading to lots of sensory input

weakness of plasticty

it can cause issues such as phantom limb syndrome in amputees which cause pain that cannot be treated

strength of functional recovery

animal study-sewed one eye of a kitten shut and found that the visual cortex of the shut eye adapted to process info from the open eye

weakness of functional recovery

many factors such as age gender and stress effect the bodies ability to recover
