Het brein - The Cerebral Cortex
4 important questions on Het brein - The Cerebral Cortex
What does the cerebral cortex consists of?
- The raised surfaces of the cortex 'gyri'
- The dips or folds 'sulci'
What are the different layers and what do they reflect?
There are six main cortical layers 'neocortex'. Then there is the mesocortex (cingulate gyrus and insula) and the allocortex (primary olfactory cortex and hippocampus).
What are the four lobes of each hemisphere?
2. Parietal lobe
3. Temporal lobe
4. Occipital lobe
Between the frontal and temporal lobes the dividing line is sometimes prominent (divided by the lateral or sylvian fissure).
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
What are the three different ways in which regions of cerebral cortex may be divided and labeled?
2. Regions divided by cytoarchitecture: Brodmann's areas = dividing the cortex up into areas based on the relative distribution of cell types across cortical layers.
3. Regions divided by function.
