Researchers use two-photon imaging and optogenetics to isolate and study brain capillaries in animal models.
Researchers have identified a neural circuit responsible for inducing insomnia associated with stress. The same neural circuit also induces changes in the immune system.
Study reveals how two neural circuits dictate the choice between social approach and avoidance. The network connecting the infralimbic cortex to the basolateral amygdala (BLA) impairs social behavior if there is a decrease in neural activity. Another network connecting the prelimbic cortex to the BLA similarly impairs social behavior if the neural activity is increased.
Researchers induced arm movements in macaque monkeys by using optogenetics to target the motor cortex.
Using optogenetics, researchers were able to manipulate oxytocin producing cells in a highly precise manner. They discovered oxytocin can amplify aggression as well as social friendliness.
Strengthened amygdala pathways increase aggression in those who have experienced trauma. The findings could lead to new treatments for PTSD.
