Abstract

Utilizing light and genetic engineering, optogenetics permits the manipulation of events within cells via light using the light-sensitive properties of single-component microbial opsins. Microbial opsins are activated by a light source, such as lasers, light-emitting diodes, and incandescent sources that deliver light to the region of interest either directly or indirectly, such as through fiberoptics. In classical in vivo optogenetics, the wiring of optic fibers necessitates tethering of animals by the optic fiber to the light source. The novel NeuroLux wireless optoelectronic system for optogenetics circumvents issues pertaining to classical optogenetics by utilizing near-field power transfer via magnetic coil antennae to power miniature, subdermal, and flexible optoelectronic implants, including an LED light sources. Furthermore, features of the NeuroLux system overcome issues posed by other wireless systems, including interference. This preliminary study sought to validate and optimize the novel NeuroLux system setup by stimulating the cornu ammonis 2 (CA2) region of the hippocampus in transgenic mice that express Cre recombinase from the vasopressin 1b receptor promoter. Following experimentation, distinct stimulation, indicated by quantified cFos expression, was noted in the CA2 region, thereby validating the use of the NeuroLux wireless optoelectronics system for future optogenetics studies.
