Exploration of the brain from its basal aspect
Medullary substance of insula
The cortex of the insula has been removed to expose the medullary substance immediately beneath it. The brain is now viewed from a slightly different angle but the configuration of branches of the middle cerebral artery is easily compared with the previous stage of dissection. The temporal lobe is not cut away further nor is the inferior occipitofrontal bundle altered. The choroid plexus is removed from the opened inferior horn of the lateral ventricle.
