Cerebral cortex Flashcards
(17 cards)
neocortex
molecular layer
external granular layer
external pyramidal layer
internal granular layer
internal pyramidal layer
fusiform layer
molecular layer
neuronal processes
external granular layer
small granule cells, intracortical connections
external pyramidal layer
smaller pyramidal cells, callosal and intracortical
INTERNAL GRANULAR LAYER
larger granular cells, inputs from the primary sensory thalamic nuclei
internal pyramidals layer
larger pyramidals cells, main output to subcortex
fusiform or multiform layer
mixture of cell types, main output to the thalamus
the function of the internal pyramidal layer
larger pyramidal cells that send output to subcortical regions
dendritic spines
where the cells connect with other neurons (synapses)
primary motor cortex
pyramidals cells
sensory cortex
more granular neurons
granular cells
shorter axons, smaller dendritic tree acts as main interneurons within cortex
where do the granular cells stay
within the cortex -> interneurons which are cells that pass signals between other neurons
gyrus
folds bumps
sulucus
grooves / lines
association
connects between lobes in the same hemisphere
