Question 1

Kandel

Answer 1

Specialised cortical areas and hemispheric dominance

Right hemisphere involved in emotion processing
If RH damaged people struggle to interpret prosody- a feature of language used to convey emotion

Question 2

Geschwind

Answer 2

1979

Specialization of the brain: homonculus’ and handed dominance

Arcade fasiculus- joining language areas laterally. Damage leads to impaired repetition

Children who are right handed but have left handed family, also benefit from integrated hemispheric dominance. I’ve better recover from strokes. Women also tend to have better integration

PROSOPAGNOSIA = failure to recognise faces. Damage to inferior occipital lobes which are a face specific area. Quite a large area in humans as this gives an evolutionary advantage to social animals

Right hemisphere involved in emotion processing

Question 3

Middle cerebral artery

Answer 3

Lateral aspect of frontal and parietal lobes (important for language)

Also branches into striate which are easily blocked and cause stroke as they are tiny

Question 4

Anterior cerebral artery

Answer 4

Medial aspect of frontal and parietal

Question 5

Posterior cerebral artery

Answer 5

Occipital lobes

Question 6

Cytoarchectonic

Answer 6

Differences in the neurone structure of the brain

Discovered by brodman and lead to his theory of specialisation and the brodman area map
