Cortex of the Brain Flashcards
Describe outputs from the neocortex
Always from pyramidal cells
Always excitatory in nature
Where is the primary somatosensory area?
Post central gyrus of the parietal lobe
Where is the primary motor area?
Pre central gyrus of the frontal lobe
Where is the primary auditory area?
Medial temporal lobe
Where is the primary visual area?
Occipital lobe
Where is the primary olfactory area?
Anterior temporal lobe (piriform cortex)
What is the function of the association areas?
Integrate information from other areas of the brain
Involved in cognition
What is the primary function of the cerebellum?
Modify movement by comparing snesory info with pre-motor information, and then affecting change
What are the names of the 3 layers of the cerebellar cortex?
Molecular layer
Purkinje layer
Granule layer
What does evidence suggest about the independent functions of the right and left sides of the brain? (hemispheric dominance)
Left - language
Right - emotion
What is the name of the fibres that mass between the two hemispheres?
Comissural fibres
What is the name of the fibres that travel from the ipsilateral cortex?
Association fibres
What did Broadmann divide the brain into based on?
Cortical cell prevalence and distribution of different cortical layers
What is the function of association areas?
Integrate and pass on information from other regions of the CNS
What are the 2 types of association area?
Unimodal - one type of modality
Polymodal - multiple modalities
