Biopsychology - Localisation Flashcards
Which lobe contains lesions if an individual has Wernicke’s Aphasia?
Temporal lobe
Outline the motor cortex’ function (3m)
Produces the movement of muscles, the left hemisphere controls the right side of the body and the right hemisphere controls the left side, it is part of the frontal lobe
Which lobe is the somatosensory cortex located in?
Parietal lobe
Which hemisphere is the auditory cortex in?
Both
Outline the Tan case study
An individual could only say the word Tan, however, he could comprehend language. Broca did a post-mortem on him - discovered lesions in the frontal lobe in the left hemisphere - when compared to normal brain.
Repeated with 8 other people.
Conclusion: Broca’s area = responsible for speech
Outline the function of the somatosensory cortex (3m)
Located in the parietal lobe, process sensations (touch, heat, pain), both hemispheres
Name the four lobes
Frontal, temporal, parietal, occipital
What profession did both Broca and Wernicke have?
Neurologists
Which cortex is in the occipital lobe?
Visual
What was the name of the psychologist who found that the Wernicke’s area was active during listening and the Broca’s area was active during reading?
Peterson et al (1988)
Who was Phineas Gage and how did he support localisation?
His frontal lobe was damaged by a metal pole penetrating his brain - his temperament changed and he became rude, suggesting that the frontal lobe regulates mood
Give one reason why the Phineas Gage case study doesn’t support localisation
There are few reports on what he was like before the accident and we are not aware of other factors that affected him
