Cone and rod function in cone degenerations

open access: yesVision Research, 1997
Progressive cone dystrophy (CD) is usually marked in the initial stages by reduced visual acuity, color vision deficiency and alterations in the photopic electroretinogram, while morphological alterations can be very mild; in some forms rods are affected in a later stage as well.

Coloring count cones of planar graphs

open access: yes, 2022
For a plane near‐triangulation G with the outer face bounded by a cycle C, let nG⋆ denote the function that to each 4‐coloring ψ of C assigns the number of ways ψ extends to a 4‐coloring of G.

Pannexin 1 Is Critically Involved in Feedback from Horizontal Cells to Cones

open access: yesFrontiers in Molecular Neuroscience, 2017
Retinal horizontal cells (HCs) feed back negatively to cone photoreceptors and in that way generate the center/surround organization of bipolar cell receptive fields. The mechanism by which HCs inhibit photoreceptors is a matter of debate.
