Activation of adenylyl cyclase by forskolin inhibited the airflow-sensitive EOG response in the MOE. A, The airflow- and odorant-sensitive EOG responses were abolished by addition of forskolin (50 µM) with IBMX (60 µM) to the MOE. Left, representative EOG traces of airflow-sensitive (i, n = 11) and odor (ii, n = 6) response; Right, bar graph of data; **, p < 0.01. B, The airflow- and odorant-sensitive EOG responses were unaffected by MDL12330A, an inhibitor of adenosine receptors. Left, representative EOG traces of airflow-sensitive (i, n = 8) and odor-response (ii, n = 7); Right, bar graph of data. N.S. not significant.
