evaluation of localisation

Question 1

brain scan evidence of localisation

Answer 1

done to show wernicke’s was active during listening task and broca’s during reading task. tulving concluded semantic+episodic memories were stored in diff parts of pre-frontal cortex= reliable theory

Question 2

neurosurgical evidence

Answer 2

lobotomy. dougherty: 44 OCD patients had cingulotomy. after 32 weeks, 1/3 had successful response. symptoms related to mental health disorders are localised to areas of brain.

Question 3

lashely’s research

Answer 3

removed 10-50% of cortex in rats- learning to navigate a maze. no area was found more imp than any other in rat’s ability to learn.holistic approach=challenged localisation.

Question 4

plasticity

Answer 4

when brain has been damaged and functions lost, rest of brain reorganises itself to recover lost function. law of equipotentiality (one part of brain is damaged, other parts of brain can take over that function) = function is not localised.
