Flashcards in 1.60 Organisation of the Cortex Deck (6)
What do projection fibres do?
Link gyri to other CNS structure
Which areas are involved with language?
Wernicke's area - language processing
Broca's - language production
Left hemisphere in most people
What is the function of the anterior cingulate gyrus?
• Larger - worrier, sensitivity, fear
• Executive processes
• Emotion particularly linked to pain
Males – smaller left anterior cingulate – less control over aggressive behaviour
What other asymmetry is there?
Leftward asymmetry – precentral gyrus, middle frontal, anterior temporal, superior parietal
Rightward assymetry – inferior posterior temporal lobe, inferior frontal lobe
visual cortex - Potentially males more cortex to process visuospatial aspects and mental rotation
What is conduction aphasia?
Association fibre damage
• Arcuate fasciculus
• (superior longitudinal fasciculus)
• Comprehension intact
• Expression is fluent
• Difficulty processing and formulating response.
Damage between wernicke's and broca's area
