Fig. 7. The POC neurons project through the medial aspect of the coc_TG to influence MCN1 and CPN2 in the CoG. (A) STNS schematic indicating the location and extent of the coc_TG transections (grey boxes), the results of which are shown in B and C. (B) Transecting the medial aspect of the coc_TG eliminated the ability of poc stimulation to trigger the gastric mill rhythm. (Left) Before medial coc_TG transection, poc stimulation triggered the gastric mill rhythm. (Right) After medial coc_TG transection, poc stimulation did not trigger the gastric mill rhythm. (C) Transecting the lateral aspect of the coc_TG did not alter the ability of poc stimulation to trigger the gastric mill rhythm. The gastric mill rhythm was triggered both (left) before, and (right) after lateral coc_TG transection by poc stimulation. B and C are from different preparations.
