However, the neural alterations that may contribute to this experience and eating behavior remain poorly understood.<\/jats:p><\/jats:sec><jats:sec id=\"S0033291722000198_sec_a2\" sec-type=\"methods\"><jats:title>Methods<\/jats:title><jats:p>We used functional near-infrared spectroscopy (fNIRS) to measure activation in the prefrontal cortices of 23 women with bulimia nervosa (BN) and 23 healthy controls (HC) during two tasks: a novel go\/no-go task requiring inhibition of eating responses, and a standard go\/no-go task requiring inhibition of button-pressing responses.<\/jats:p><\/jats:sec><jats:sec id=\"S0033291722000198_sec_a3\" sec-type=\"results\"><jats:title>Results<\/jats:title><jats:p>Women with BN made more commission errors on both tasks. BN subgroups with the most severe LOC eating (<jats:italic>n<\/jats:italic> = 12) and those who felt most strongly that they binge ate during the task (<jats:italic>n<\/jats:italic> = 12) showed abnormally reduced bilateral ventromedial prefrontal cortex (vmPFC) and right ventrolateral prefrontal cortex (vlPFC) activation associated with eating-response inhibition. In the entire BN sample, lower eating-task activation in right vlPFC was related to more frequent and severe LOC eating, but no group differences in activation were detected on either task when this full sample was compared with HC.
