He chose to investigate the connection between stress and posture after developing a method to introduce a virus into an organ.
"We injected the adrenal medulla with a virus and traced it back into the brain all the way to the cerebral cortex," he said to NPR.
One such unexpected finding is that the "thinking" parts of the human brain are not the only ones involved in the stress response.
According to the NPR story, "other parts of the brain are also sending signals to the adrenal medulla," including the areas that regulate muscular function.
Other studies have found a similar link between poor posture and emotional distress.
Participants who stood taller had "higher self-esteem," "more arousal," "better mood," and "less fear," the research found.
