Resumen del Recurso
Localisation of function in the brain
Phineas Gage case study
rail road accident, helped aid understanding about brain localisation
Iron pole through cheek
caused a personality change (rude and aggressive)
must be careful about not generalising findings
Hemispheric lateralisation
left hemisphere processes information from the right side and vice versa (contralaterality)
Brocas area- producing speech
Wernickes area- understanding speech
auditory centres- receives information from the cochlea. Left ear information goes to the right auditory cortex etc
Evaluation
Equipotentiality
Ashley could not find a specific area of rats brain that were responsible for specific memories
wary about applying animal studies to humans
plasticity
intact healthy areas of cortex to take over cognitive functions of the brain damaged areas
degree of brain damage is not caused by localisation of damage but the extent of the damage
importance of communication
brain areas may be less isolated than first thought
eg Wernicke stressed how brain areas were interdependent
damage to brain area connections causes lower cognitive function
damage between visual and wernickes lowers reading ability
evaluation
Brocas area not solely responsible for speech
MRI scans in the late 1800s show damages to other areas of brooks areas too
Aphasia
inability to understand or produce speech
Individual differences
Baheveliar
differences in activation across the right temporal lobe and left frontal, temporal and occipital lies during a silent reading task
reported a greater use of language by women is reflected in their proportionally larger brooks and wernickes area
