Techniques for extraction of depth-resolved in vivo human retinal intrinsic optical signals with optical coherence tomography.

6 Sep 2009 PURPOSE: To demonstrate acquisition and analysis methods for depth-resolved observation of slow retinal physiology induced changes in infrared backscatter in vivo. METHODS: A dark-adapted human was briefly subjected to a localized photobleach. For ... Read more...

Origins of retinal intrinsic signals: a series of experiments on retinas of macaque monkeys.

6 Sep 2009 Diffuse flash stimuli applied to the ocular fundus evoke light reflectance decreases of the fundus illuminated with infrared observation light. This phenomenon, which is independent of the photopigment bleaching observed as an increase in the ... Read more...

Genetic dissection of rod and cone pathways in the dark-adapted mouse retina.

6 Jul 2009 A monumental task of the mammalian retina is to encode an enormous range (>10(9)-fold) of light intensities experienced by the animal in natural environments. Retinal neurons carry out this task by dividing labor into many parallel rod and cone ... Read more...
