Behavioural and physiological limits to vision in mammals.
(Philosophical transactions of the Royal Society of London. Series B, Biological sciences, 2017-04)
Human vision is exquisitely sensitive-a dark-adapted observer is capable of reliably detecting the absorption of a few quanta of light. Such sensitivity requires that the sensory receptors of the retina, rod photoreceptors, ...
Distribution and diversity of intrinsically photosensitive retinal ganglion cells in tree shrew.
(The Journal of comparative neurology, 2017-12-14)
Intrinsically photosensitive retinal ganglion cells (ipRGCs) mediate the pupillary light reflex, circadian entrainment, and may contribute to luminance and color perception. The diversity of ipRGCs varies from rodents to ...
Cell type-specific changes in retinal ganglion cell function induced by rod death and cone reorganization in rats.
(Journal of neurophysiology, 2017-07)
We have determined the impact of rod death and cone reorganization on the spatiotemporal receptive fields (RFs) and spontaneous activity of distinct retinal ganglion cell (RGC) types. We compared RGC function between healthy ...
"Silent" NMDA Synapses Enhance Motion Sensitivity in a Mature Retinal Circuit.
Retinal direction-selective ganglion cells (DSGCs) have the remarkable ability to encode motion over a wide range of contrasts, relying on well-coordinated excitation and inhibition (E/I). E/I is orchestrated by a diverse ...
