Environmental regulation of opsin expression and spectral tuning in the vertebrate retina (2004–2006)
- Exciting new evidence shows that the vertebrate visual system is extraordinarily plastic and that the colour and brightness of the ambient light regulates both the spatial and temporal expression of visual pigments (opsin) genes and the degree of spectral filtering in the retina. Based on findings that more than one visual pigment can be co-expressed in a single photoreceptor type we plan to manipulate the light environment in order to identify and quantify the effect of different lighting regimes by morphological spectral and molecular techniques in a concerted effort to understand the regulation of opsin expression.
