King-Wai Yau教授,1975年在哈佛大学获博士学位,1975-1986年先后在斯坦福大学、剑桥大学、UTMB Galveston工作。1986年至今任约翰霍普金斯大学神经科学系教授。主要从事视觉和嗅觉机制研究,150余篇论文中有38篇发表在Nature、Science和Cell。曾获多种学术奖项。2010年当选美国科学院院士。
Rods and cones not only absorb light for initiating image vision, but also contribute to non-image vision, including circadian photoentrainment, pupillary light reflex, etc. A recent surprising discovery is that ganglion cells, which convey rod/cone signals to the brain, are themselves photosensitive by expressing a visual pigment, melanopsin. These cells, similar to rods, have high signaling efficiency capable of single-photon detection. However, they have an extremely low pigment density (compared to rods and cones). We are studying the phototransduction mechanism in these fascinating, newly-discovered photoreceptors, which does not appear to involve cGMP as in rods and cones.
