Temporally precise, noninvasive control of neural circuitry is a long-sought goal of neuroscientists and biomedical engineers. Stanford University researchers in the laboratory of Dr.
Researchers in the laboratories of Dr. Karl Deisseroth and Dr. Peter Hegemann have engineered mutant ChR2 (Channelrhodopsin-2) proteins with light-sensitivity that is increased by orders of magnitude compared to wild-type ChR2.
Researchers in Prof. Karl Deisseroth's lab have discovered and engineered new microbial opsin proteins and cell trafficking tools to enable selective cell-type specific, light-sensitive switches for neuromodulation.
Researchers in Prof. Karl Deisseroth's laboratory have developed a portfolio of microbial opsin proteins that can be used for precise and modular photosensitization components that enable optical control of specific cellular processes.
Researchers in Dr. Karl Deisseroth's lab have engineered a channelrhodopsin variant that can be stimulated by red light and has fast stimulation frequencies. In neurons, channelrhodopsins are light activated protein channels that induce action potential firing.
Researchers in Dr. Karl Deisseroth's lab have created inhibitory channelrhodopsins (ChRs) that allow fast, reversible inhibition of electrical signals in neurons. Optogenetics is a technique used to understand normal and pathological neural circuitry.
Researchers in Prof. Karl Deisseroth's laboratory have developed a system to enhance optogenetic pumps using one tool to address current limitations in both inhibition and excitation.
