Optogenetics allow researchers to either activate or inhibit neurons in the brain. To see how this affects behavior, you need to record that behavior and synchronize it with the stimulation. Here's how.
Optogenetics has been invaluable in many brain studies, chemogenetics has been a good non-invasive alternative. Magnetogenetics is the new kid on the block. Can it do better?
Craving a snack, the joy of eating it. The part of our brain that regulates this is the lateral hypothalamus. An interesting targer for addiction and eating disorder research.
A great example of optogenetics in behavioral studies is the work of Dr. Kravitz and Dr. Kreitzer at the Kreitzer lab (currently, Kravitz works at the NIDDK in Bethesda). Let me tell you about it.
Brains are complicated. We all know that. Like an entangled bunch of wires. Still, over the years, neuroscientists have been able to map out several brain regions and their functions in behavior and physiology.
