Optical recording of different tissues such as the cortex, xylem and pith.
(a) An image of a radial face paraffin section that was made at the end of the experiment showing different tissues such as the cortex, xylem and pith. (b) A series of consecutive raw fluorescence images. (c) Time lapse ∆F/F images. No variation in the fluorescence intensity was observed. (d) The results of the optical recording. There was no ΔF/F change in the cortex, xylem or pith tissues, although the APs were recorded using the Ag/AgCl electrode.
