 +===== MRSI =====
 +
 +Interest in Thalamus from Sarpal, via FC:
 +> [[:brain:NAAG]] is meant to modulate glutamatergic activity, so quetion was whether this predicts thalamic functional connectivity 
 +> running a seeded [[brain:functionalconnectivity]] analysis on the thalamus and regressing voxelwise values vs NAAG seemed like a relatively easy thing to check
