Cerebrum: Int Object
| Question | Answer |
|---|---|
| archicortex - oldest | 3 layers, has the hypocampus |
| paleocortex | 3 layers, olfactory cortex |
| neocortex | newest part, 6 layers |
| subcortical grey | basal nuclei and deincephalon |
| basal nuclei | basal ganglia |
| diencephalon | thalamus and hypothalamus |
| neocortex I | molecular, mostly dendrites |
| neocortex II | external granular, granular neurons |
| neocortex III | external pyramidal |
| neocortex IV | internal granular |
| neocortex V | internal pyramidal (connects to upper level) |
| neocortex VI | multiform |
| association fibers | connect ipsilateral cortical areas, connect short (gyri) and long (lobes), superior longitudinal fasciculus, cingulum, and the uncinate fasciculus |
| AF superior longitudinal fasciculus | connects anterior to posterior |
| cingulum | connects medial section of the brain above corpus colosseum |
| uncinate fasciculus | connects frontal (anterior) to temporal (anterior portion) |
| commissural fibers | cross from one side of the cerebrum to the other, corpus callosum and anterior commissure. |
| corpus callosum | connects all lobes |
| anterior commissure | connects anterior temporal lobes |
| projection fibers | connects cortex with subcortical structures, looks like it branches from cortex down to brain stem and visa versa |
| corona radiata | fibers projecting from the cerebral cortex through the internal capsule and into the brainstem |
| ID lateralized specialization | |
| basal nuclei | caudate, globes pallidus, and putamen - group of subcortical nuclei situated at the base of the forebrain and top of the midbrain |
