Testing light at different wavelengths, the team found that these fish horizontal cells are thousands of times less light sensitive than their partner cone cells.
The bottom line is that the light effect on the horizontal cells is subtle, perhaps to allow the eyes of these animals to fine-tune their functions to different ambient light conditions," said Yau.
Under these conditions, a steady differential signal was obtained from horizontal cells indicative of a higher concentration of hydrogen ions near the membranes of the cells.
In this context, it is interesting to note that glutamate has previously been reported to promote an acidification of the internal milieu of catfish retinal horizontal cells as measured using the pH-indicator dye BCECF [11].
This compound blocks sodium, potassium and calcium channel conductances in isolated skate horizontal cells (4).
Skate horizontal cells are isolated as follows: the eyes are removed, and the retina separated from eyecup pieces.
Horizontal cells displayed an apparent steady-state efflux of calcium under these experimental conditions.
However, these alkaloids also appeared to promote an increase in membrane conductance when the horizontal cells were held at potentials more positive than 0 mV.
