Summary: Oriens lacunosum-moleculare (O-LM) interneurons constitute 40% of hippocampal interneurons expressing Somatostatin (SST). Recent evidence has indicated a dual origin for these cells in the medial and caudal ganglionic eminences (MGE and CGE). with expression of Htr3a as a distinguishing factor. This is strikingly different from cortical SST interneurons that have a single ori... https://www.jmannino.com/quick-save-Arcade-Smokey-Bear-Belt-p10222-great-pick/
