This is a realistic model of the subcortical structures of the human brain (without cortex), which is convenient for displaying their anatomy as well as their functional connections.
It contains the following objects:
1.) brainstem (medulla + pons), midbrain, thalamus, hypothalamus, pituitary gland and optic chiasm
2.) striatum (caudate-putamen and nucleus accumbens), amygdala
3.) nucleus pallidus
5.) fornix with mammillary bodies
6.) corpus callosum
It was modelled with Blender 2.70a and rendered with Cycles. The Glossy varnish-like materials are added.
