They also used a technique called optogenetics to turn parts of this brain circuit on or off in different emotional and behavioral contexts while measuring the animals' breathing and behavior.

While the study provides groundbreaking insights, the researchers acknowledge limitations, such as not measuring phenol levels in children directly.

Along with measuring accuracy, the team evaluated the models' adherence to clinical instructions.

"This model is the first one capable of measuring those parameters," Medvedev said.

By measuring how long it takes for the beams to bounce back, scientists can make a 3D map of the ground below.
