Optogenetics
Optogenetics allows for the precise control of individual neurons in the brain. By genetically engineering neurons to express light-sensitive proteins, researchers can manipulate these neurons simply by shining light on them. This can help us better understand the roles that specific brain regions and neural circuits play in shaping animal behavior.
A to Z on optogenetics and video tracking studies
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.
Motivation and eating: deep brain imaging in freely moving mice
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.
Optogenetics and operant conditioning
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.
Optogenetics - Shining a light on brains and behavior
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.
