Investigating Predatory Behavior Using Optogenetics

Posted by Ready Lasers on

   The latest research related to behavioral optogenetics is a study at Yale University that investigates predatory hunting behavior in mice. The paper, published in the January 12 issue of Cell, describes how the researchers isolated the brain circuitry that coordinates hunting. One set of neurons in the amygdala, the brain's center of emotion and motivation, cues the animal to pursue prey. Another set signals the animal to use its jaw and neck muscles to bite and kill. The researchers used a blue DPSS 473 nm laser to selectively excite the neurons. They observed that when the laser was...
