Figure 7. Intravenous injection of the 5-HT1A antagonist, WAY100635, inhibits chorda tympani neural responses to lingually applied 0.5 M NaCl, 0.03 M Quinine, 1.0 M Sucrose, or 0.01 N HCl.
Sample responses are illustrated prior to (PRE), immediately following (AFTER), and 45 to 60 minutes following (RECOVERY) a single bolus intravenous injection of 100 µM WAY100635 (upper left). Summarized data are presented in the histogram (upper right) for these four stimuli. In the lower figures, summarized data for four concentrations of WAY100635 are presented for each tastant and compared to vehicle (saline) injection.
