 So we cut the brain in half into its left and right hemisphere, right? So this is a half brain that we're looking at Internally here, so we have our corpus callosum, which is actually the connection point between the left and right hemisphere Remember they're separated by that longitudinal fissure, which is where this brain will be cut and so you have the corpus callosum there to communicate between Let's see you have the septum pellicidium which would sit right here, and it actually separates two of our ventricles our lateral ventricles We have the mass intermediate here You have the hypothalamus and the thalamus Our pineal gland sits back in the back the midbrain is right next to it Again, we can see the medulla album got a cut here and the ponds cut here We can see so this is the cerebellum cut and The arbor vitae, which is the white part the white matter within the cerebellum
