CT whole nerve activity in response to lingual application of NaCl, QHCl, monosodium glutamate (MSG) + water, MSG + ethanol (EtOH) and MSG + 88 μM LA. A and C: representative traces of CT whole nerve activity (μV) from a male (A) and a female (C) rat. Gray, raw nerve activity; black, integrated, rectified activity. B and D: mean ± SE CT response to MSG and MSG + 88 μM LA by male (B) and female (2D) rats. For each concentration of MSG: significantly different from MSG (a) and female significantly different from male (b).
