Phototransduction is the best studied example of a GTP binding protein (G protein)-coupled signal transduction pathway. A great body of knowledge about phototransduction has been established in the ...

Phototransduction in humans occurs in the retina. "I wouldn't call this vision, because as far as we know the hydra are not processing information beyond what's light and what's dark, ...

Phototransduction is the conversion of light signals into electrical signals in photoreceptive neurons and underlies both image-forming and non-image-forming light sensing.

Drosophila phototransduction has served as a model system for elucidating the molecular basis of sensory signal processing. In the fruitfly’s photoreceptors, light is captured by rhodopsin and ...
