WebPurpose: Photophobia is a common symptom in individuals suffering from traumatic brain injury (TBI). Recent evidence has implicated blue light-sensitive intrinsically photosensitive retinal ganglion cells (ipRGCs) in contributing to the neural circuitry mediating photophobia in migraine sufferers. WebSep 26, 2016 · The experiments to rescue ipRGC function by chemogenetic activation and melanopsin restoration were very nicely done and will be useful tools for future studies. The authors state throughout the paper that, depending on the duration of the light stimulus (transient vs. sustained), the combination of inputs/outputs of ipRGCs mediating pupil ... WebNov 28, 2024 · The proposed function of irradiance-dependent control of RGC firing rate relies upon a causative relationship between this parameter and information flow. Our results indicate that this effect is mediated by ipRGC-dependent increases in gain of visual responses across a large RGC population. green bay packer shirts for men
