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.
Stress might seem like a bad word, but it does have its perks. A recent study by Rodrigo J. De Marco uncovered the role of the pituitary in zebrafish larvae behavior after the onset of stress.
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.
By this point, we do not need to tell you how popular zebrafish are. We also probably do not need to point out the great technological advances that are being made in research because of the use of optogenetics.
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.
