Autophagy supports color vision [PDF]
Autophagy, 2015 Cones comprise only a small portion of the photoreceptors in mammalian retinas. However, cones are vital for color vision and visual perception, and their loss severely diminishes the quality of life for patients with retinal degenerative diseases. Cones function in bright light and have higher demand for energy than rods; yet, the mechanisms that ...

Variability and systematic differences in normal, protan and deutan color naming
Frontiers in Psychology, 2014 Congenital color vision deficients generally demonstrate difficulties in color naming tasks. In our study we investigated the color naming properties and uncertainties of a relatively large group of red-green color vision deficients using quasi ...

Vision through colored eyes [PDF]
Naturwissenschaften, 1995 The conspicuous eye-color patterns of tabanid flies have been frequently portrayed. The eye colors originate from cornea color filters, which, on.the one hand, cause colorful reflections and, on the other, alter the spectral composition of transmitted light.

Unsupervised Visual Feature Learning with Spike-timing-dependent Plasticity: How Far are we from Traditional Feature Learning Approaches? [PDF]
, 2019 Spiking neural networks (SNNs) equipped with latency coding and spike-timing dependent plasticity rules offer an alternative to solve the data and energy bottlenecks of standard computer vision approaches: they can learn visual features without ...

Molecular Genetics of Color Vision and Color Vision Defects [PDF]
Archives of Ophthalmology, 2000 Color is an extremely important component of the information that we gather with our eyes. Most of us use color so automatically that we fail to appreciate how important it is in our daily activities. It serves as a nonlinguistic code that gives us instant information about the world around us.
