Outline of Final Research Achievements |
Retinal bipolar cells relay important visual information that enables, for example, contrast and edge detection. We focused on TRPM1 and mGluR6 that regulate retinal ON bipolar function by using mutant mice. We observed oscillatory spontaneous activity only in TRPM1 mutant mouse retina. The oscillations result from morphological changes in the ON bipolar cell synaptic terminal, consistent with a mathematical model. We also developed operant systems for studying visual acuity in mice. Altogether, we have established a general toolbox that can be used to study visual function from molecules to consciousness in an area of relevance to retinal regeneration.
