SCN8A encodes a major voltage-gated sodium channel expressed in CNS and PNS neurons. Gain-of-function and loss-of-function mutations contribute to human disorders, most notably Developmental and Epileptic Encephalophy (DEE). More than 600 affected individuals have been reported, with the most common mechanism of de novo, gain-of-function mutations. We have developed constitutive and conditional models of gain- and loss- of function mutations in the mouse and characterized the effects of on neuronal firing and neurological phenotypes. Using CRE lines with cellular and developmental speci

Controlling biological processes using light has increased the accuracy and speed with which researchers can manipulate many biological processes. Optical control allows for an unprecedented ability to dissect function and holds the potential for enabling novel genetic therapies. However, optogenetic experiments require adequate light sources with spatial, temporal, or intensity control, often a bottleneck for researchers. Here we detail how to build a low-cost and versatile LED illumination system that is easily customizable for different available optogenetic tools. This system is configurab
