Rod nuclear architecture determines contrast transmission of the retina and behavioral sensitivity in mice

STRIA TECH

The chromatin in the nucleus of rod photoreceptors has an inverted structure in nocturnal animals. Metabolically, this is expensive to maintain, so it has been proposed that the inverted architecture provides an advantage during night vision. Subramanian et al could show with our OptoDrum that the inverted nuclear architecture provides improved contrast sensitivity in dark environments.

Journal Club: Measuring Visual Acuity and Contrast Sensitivity by Optomotor Reflex in Rodents

STRIA TECH Events, Journal Club

In vision research, observing the optomotor reflex (OMR) is an important and widely established method for assessing visual acuity and contrast sensitivity in rodents. In this event, we will hear about several applications of OMR measuremnts, ranging from quantification of retinal degeneration to characterization of night vision.

ScotopicKit

Striatech’s ScotopicKit lets you extend the applications of your OptoDrum. With filter foils, you can stepwise reduce absolute light levels inside the OptoDrum to near darkness. Whether you want to monitor rod-based diseases, or ask questions about light adaptation – with the ScotopicKit you can evaluate your animals’ visual threshold at different light levels, and characterize rod-driven vision.
