Using optogenetics to study aggression in mice
17:22 - 27:32 (10:10)
Dayou found a way to evoke aggression in mice by activating specific neurons in the ventromedial hypothalamus using optogenetics. While defensive rage and predatory aggression were mapped out through earlier studies, the encoding of the former remains a mystery.

Researchers have discovered that aggressive behavior can be elicited by stimulating the ventromedial hypothalamus, an area of the brain that contains fear neurons.

Summary
Researchers have discovered that aggressive behavior can be elicited by stimulating the ventromedial hypothalamus, an area of the brain that contains fear neurons. Using optogenetic stimulation, it was found that male mice displayed offensive aggression that was rewarding when the ventromedial hypothalamus was stimulated.

The encoding of defensive aggression in the brain and how it works are still mysteries that haven't been solved.

Summary
The encoding of defensive aggression in the brain and how it works are still mysteries that haven't been solved. It can be difficult to differentiate between offensive and defensive aggression in mice fights but it's much clearer in rats.
