  1. Phototransduction and retinal degeneration in Drosophila

    Drosophila visual transduction is the fastest known G-protein-coupled signaling cascade and has therefore served as a genetically tractable animal...

    Article 09 May 2007
  2. Role of a novel photopigment, melanopsin, in behavioral adaptation to light

    Adaptation to changes in the ambient light is of critical importance to life. In mammals, three principal photoadaptation mechanisms depend on ocular...

  3. Light During Darkness and Cancer: Relationships in Circadian Photoreception and Tumor Biology

    The relationship between circadian phototransduction and circadian-regulated processes is poorly understood. Melatonin, commonly a circadian phase...

    Article 01 May 2006
  4. Neuronal Input Pathways to the Brain's Biological Clock and their Functional Significance

    Rhythmic changes in physiology and behaviour within a 24 h period occur in living organisms on earth to meet the challenges associated with the daily...

    Article 26 January 2005
  11. Molecular and Functional Diversity of Visual Pigments: Clues from the Photosensitive Opsin–Like Proteins of the Animal Model Hydra

    The primary event of vision is the absorption of photons by photosensitive pigments, which triggers the transduction process producing the visual...
    Silvia Santillo, Pierangelo Orlando, ... Carlo Musio in Brain, Vision, and Artificial Intelligence
    Conference paper 2005
  12. Preservation of the entire population of normally transient ipsilaterally projecting retinal ganglion cells by neonatal lesions in the rat

    The number of ipsilaterally projecting retinal ganglion cells (IPRGCs) in develo** normal rats and rats which received unilateral thalamic lesion...
