1. Neuroanatomy Lab 1 Module 1.4: The Diencephalon Neuroscience Block Drs. Georgia Bishop and Chris Pierson Jacobus Sylvius Thomas Willis Santiago Ramón y Cajal Paul Edinger

2. Module Purpose To facilitate small group learning by providing step-by-step guidance to assist in the identification of important neuroanatomic structures and relationships while providing a foundation on which to build clinical knowledge and skills

3. Learning Outcomes/ Competencies At the end of this module you will have enhanced your vocabulary and understanding of important neuroanatomical relationships of the diencephalon in preparation for more detailed and complicated topics later in the Neuroscience Block and for future clinical applications.

4. Objectives 9971: Explain basic terminology related to the organization of the central and peripheral nervous system. 10020: Describe the location and relationships of relevant nuclei in the CNS on gross brain specimens, cross sectional material, and radiographic images. 10046: Describe the location and relationships of relevant descending tracts in the CNS on gross brain specimens, cross sectional material, and radiographic images.

11. In conclusion…. You should now be able to recognize key neuroanatomic landmarks and structures of the diencephalon At the end of the lab you should understand a number of important neuroanatomical relationships of the diencephalon The relationships emphasized in lab are relevant to actual clinical problems you will encounter in your Neurology clerkship and throughout your career You will be expected to use this new vocabulary fluently in the Neuroscience Block as more detailed and complicated topics are introduced and in future clinical applications such as your Neurology clerkship
