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 ...
Originally published Mar 8, 2016 and last updated Sept 3, 2020 by Nyla Naim. Scientists around the world have been making major improvements to CRISPR technology since its initial applications for genome engineering in 2012. Many of these advances have stemmed from the goal of ...
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 ...
This post was contributed by Alessia Armezzani, scientific communication manager at genOway. A few decades ago, the brain remained elusive, not from a lack of intellectual curiosity on the part of scientists but, rather, from the limited technologies available. Over the past few ...
Optogenetics, the use of light sensitive proteins (opsins) to manipulate cell activity, enables researchers to silence or incite neuronal firing and study subsequent effects on behavior. The system is an especially powerful tool for in vivo behavioral studies because it is ...
