A blue-light photoreceptive CRYPTOCHROME (PCRY) is important in providing light input to the clock by triggering the degradation of TIMELESS (Hardin, 2005; Rosato et ai.

Specialized photoreceptive cells in the retina detect a restricted bandwidth of visible light; this information projects directly to the suprachiasmatic nucleus (SCN), the central circadian pacemaker, that triggers the pineal gland to produce this indoleamine during darkness [6, 12-14].

Retina is a photoreceptive tissue, whose energy consumption changes depending on light exposure.
(This is not an accident.) But because the eye is naturally exposed to light, it's the perfect venue for a trial like this one, which seeks to switch the photoreceptive burden from the compromised rods and cones to ganglion cells deeper in the retina.
For example, Opsin 5 in the paraventricular organ of quail appears to be a deep brain photoreceptive molecule that regulates seasonal reproduction in birds [7].

The active substance in GLIOLAN, aminolevulinic acid (ALA), is a photoreceptive compound which is absorbed by cells in the body, where it is converted by enzymes into fluorescent chemicals, particularly protoporphyrin IX (PPIX).
