Question | Answer |
---|---|
What are the specific thalamic relay nuclei? | Lateral Nuclear Group Lateral Dorsal Nucleus Lateral Posterior Nucleus Ventral Medial Nucleus Medial Nuclear Group (MD) Anterior Nuclear Group Midline Thalamic Nuclei |
Where are the specific relay nuclei located? | Mainly in the lateral thalamus |
All sensory modalities EXCEPT which have specific relays in the lateral thalamus? | Olfaction |
