Adaptation to the prismatic effects of refractive lenses.

abstract：:Glutamate is the major excitatory neurotransmitter in the vertebrate retina. Native glutamate transporters have been well characterized in several retinal neurons, particularly from the salamander retina. We have cloned five distinct glutamate transporters from the salamander retina and examined their localization and...
