Similarities between lateral inhibition in the vertebrate retinal system and the insect olfactory system. (a) Ambient light intensity modulates light sensitivity in retinal ganglion cells. Modified from [4]. (b) Similarly, high odor concentrations recruit more odorant receptor neurons, down shifting the sensitivity of the corresponding projection neuron in Drosophila antennal lobe. Modified from Figure 7 of Asahina et al. [3], with the dashed line indicating potential projection neuron response in normal larvae.
