Maurice Flashcards
Differences in motor and sensory humunculus
.
Neocortex?
made up of 6 layers of cells
Allocortex?
Heterogenous mix of cell types with 3 layers
related to hippocampus, primitive brain inputs from olfactory system, limbic system(flight or fright)
Allocortex location
?
Connections of the cerebral cortex?
Association fibres (eg. arcuate fasciculus)
Commissural fibres (eg. corpus callosum)
Projection fibres (eg. internal capsule)
6 layers of the neocortex?

Efferent and Afferent fibres of the cortex?
.
Heterotypical vs Homotypical cortex?
.
Example of each type?
.
Blood supply of the cortex?
.
Clinical chat on brain blood supply?
middle cerebral
berry aneurysms-> rupture -> sub-arachnoid haemorrhage -> later bo
Thalamus function simply?
…
Structure and function of thalamus?
…..
Papez circuit?
…..
Where is it important?
The anterior thalamic nucleus plays a part in allowing us to bring infor from the hippocampus to the frontal cortex and ‘remember things’.
Also allows us to not go into fight or flight response all the time (Eg. burnt toast scenario)
Internal capsule location
separates lenticular nucleus from the caudate nucleus
Internal capsule structure
More medial aspects contain sensory firbres coming in and lateral aspects contain motor fibres heading out the the body
The bend is called the knee or GENU and the motor fibres heading to the face can normally be found here.
