Fig. 6. Intracellular recording traces of responses to three unpolarized monochromatic light stimuli in TuTu1 neurons. (A) TuTu1 is excited by UV light (double arrowhead) and is inhibited by green light (open arrowhead) when stimuli are applied from the ipsilateral direction (Ipsi). The neuron shows inhibitory responses (arrows) with rebound excitation (double open arrowheads) to UV and blue light applied from the contralateral direction (Contra). (B) In another recording TuTu1 is inhibited by dorsal (Dors) and contralateral blue light (arrows). Ipsilateral UV and blue light lead to excitations (arrowheads). Positive deflections in the bottom trace indicate duration of light stimuli. Maximum intensity (0 log) is 16.5x10¹² photons cm^–2 s^–1.
