Fig. 5. Serotonin increased the duration of the optical response in both the
macroglomerular complex (MGC) and the ordinary glomeruli (Gs). Serotonin
application significantly increased the duration of the optical response in
the MGC from 6.6±0.2 ms to 8.3±0.2 ms (P<0.005,
N=7) and in the Gs from 8.3±0.2 ms to 10.1±0.2 ms
(P<0.005, N=5). Error bars represent S.E.M.
