Parietal association cortex
Spatial skills 3D recognition Shapes Faces Written word Concepts Abstract perception
Frontal association cortex
Intelligence Personality Behaviour Mood Cognitive function
Supramarginal language area (SMGLA)
Angular gyrus language area (AGLA)
McDonalds M- focuses on reading and writing
Broca’s Area aphasia
Hear and understand words BUT cannot pronounce words (Non-fluent Aphasia)
Wernicke’s area aphasia
Can hear BUT cannot understand words (fluent aphasia)
Disconnection aphasia (aka conduction aphasia)
Broca’s and Wernicke’s areas are disconnected therefore speech doesn’t make sense - talk about two different topics at the same time
