Pause the video at each structure and name it before you open the answers.
Show the answers
- Caudate nucleus: its head bulges into the frontal horn of the lateral ventricle. In Huntington's disease it wastes away and the horn widens.
- Thalamus: every sense except smell is relayed here on its way to the cortex.
- Putamen: the most common site of a hypertensive brain bleed.
- Globus pallidus: its inner part (GPi) is a deep brain stimulation target in Parkinson's disease and dystonia.
- Hippocampus: key for forming new memories. It shrinks in Alzheimer's disease.
