In 2005, Boyden et al. described the first light-activated tool for controlling neuronal activity, channelrhodopsin-2 (ChR2), a blue light-activated cation channel, from the archaebacteria Chlamydomonas reinhardtii. When exposed to blue light, this channel activates neuronal ...

This post was contributed by Adriana Galvan, an associate professor at Emory University School of Medicine. Optogenetics and chemogenetics are powerful tools to modulate the activity of neurons and other brain cells. Since the opsins or chemogenetic receptors used in these ...
Optogenetics is a neuroscience method that lets you fire neurons with the flick of a light switch. Neurons are not typically persuaded to fire when light is shined on them, but the expression of light-gated ion channels such as channelrhodopsins (ChRs) makes them ...

Chemogentic and optogenetic technologies have pushed the boundaries in neuroscience by granting targeted control over neuronal activity. While they serve similar purposes, both techniques offer researchers different advantages and limitations. The four main factors in which ...
It’s time to choose your own protein purification adventure. You want to purify your favorite protein (YFP). You have two options: Option #1: Affinity tag purification You tag YFP and use an affinity column for purification. After binding YFP to the column, you wash several ...
