A, B, In the absence of adaptation (A, B), lateral inhibition (B) sharpens the PN tuning profile (blue). C, D, In the presence of adaptation, the PN tuning profile is not affected by lateral inhibition. The tuning profile was obtained by averaging PN firing rates during the 1 s stimulation window and across 50 trials. PNs receive input from ORNs of the corresponding type according to the receptor response profile. The receptor response profile (gray), rescaled between the minimum and maximum PN firing rates, is shown in all panels for comparison. The insets show the input–output relation between the ORN and the PN firing rates. Both averaged (blue line) and single-trial (gray crosses) PN firing rates are shown. Download Figure 2-1, TIF file.
