FIGURE 1.
Optical triggering of neurosecretion. (A) Diagram of the experimental approach. Secretion upon light stimuli was detected by amperometry in LiGluR(+) chromaffin cells while VGCC where blocked by toxins (Vox, oxidation voltage; SV, secretory vesicle). (B) Amperometric current recording (black plot) from a single LiGluR(+) cell in response to 5 s, 380 nm light pulse (red plot), and the secretory rate (green plot).
