What A Grateful Brain Looks Like

Evidence is mounting that gratitude makes a powerful impact on our bodies, including our immune and cardiovascular health. But how does gratitude work in the brain?
A team at the University of Southern California has shed light on the neural nuts and bolts of gratitude in a new study, offering insights into the complexity of this social emotion and how it relates to other cognitive processes.
“There seems to be a thread that runs through subtle acts of gratitude, such as holding a door for someone, all the way up to the big powerful stuff like when someone gives you a kidney,” says Glenn Fox, a postdoctoral researcher at USC and lead author of the study. “I designed this experiment to see what aspects of brain function are common to both these small feelings of appreciation and large feelings of gratitude.”
In their experiment—which was partially funded by a grant from the Greater Good Science Center’s Expanding the Science and Practice of Gratitude project—Fox and his team planned to scan participants’ brains while they were feeling grateful to see where gratitude showed up.
But first, they had to induce gratitude. At USC’s Shoah Foundation, which houses the world’s largest collection of Holocaust testimonies, they poured over hundreds of hours of footage to identify compelling stories of survivors receiving aid from others.
“Many of the survivors talked about receiving life-saving help from other people—from being hidden by strangers during the middle of the Nazi manhunt to being given a new pair of shoes during a wintertime march,” says Fox. “And they also talked about less significant gifts, such as bread or a bed at night.”
