Figure 7


Fig. 7. Summary diagram of response properties of LoTu1 and TuTu1. (A) LoTu1 neurons are excited by ipsilateral unpolarized green light at elevations between 30 and 45° (Green +). Unpolarized UV light from the same range of directions leads to inhibition (UV –). The neurons are also inhibited by dorsal unpolarized blue light (Blue –). Dorsal polarized blue light activates LoTu1 neurons (Pol Blue +); the strength of activation is dependent on the e-vector orientation. (B) TuTu1 neurons are excited by ipsilateral unpolarized UV light at elevations between 30 and 45° (UV +). Unpolarized green light from the same directions leads to inhibition (Green –, observed in half of the recordings). Contralateral blue light at elevations between 30 and 45° (Blue –) inhibits TuTu1 neurons. Dorsal polarized blue light leads to sinusoidal modulation of the neuronal activity with excitatory and inhibitory components depending on the e-vector orientation (Pol Blue ±).
