Dr. Jinks' research focuses on two important questions in invertebrate visual neuroscience:
1) How is the function of the retina influenced by input from the brain? Circadian efferent input to the retinas of the eyes of the horseshoe crab Limulus polyphemus regulates the sensitivity of the eyes to light and synchronizes the retina's daily metabolism (e.g., daily turnover of the photosensitive membrane). The IVNL is currently investigating how the phototransduction cascade, especially those branches that regulate and synchronize photosensitive membrane shedding, is influenced by input from the brain.
2) How are the retinas and eyes of deep-water crustaceans engineered to exploit dim environmental light sources? After working on a team that described the unique eyes of a number of new hydrothermal-vent dwelling shrimp living in an environment that is not privy to sunlight, Dr Jinks and his students are now looking at how the eyes of a hydrothermal vent crab, Bythograea thermydron, are modified over the animals life cycle to make use of the dim light emanating from the hydrothermal vents.
