Changes in neural activity of the prefrontal cortex during eating in humans

Interaction of Protein Preloads and Physical Activity on Intake of an Ultra-Processed, High Sugar/High Fat Food/Low Protein Food

“…A two-minute fNIR recording was obtained prior to participants being provided with the HSFLP (a name brand vanilla ice cream, (1.99 kcal/gram) at 20 min postpreload and allowed to eat ad libitum for a maximum of 10 min. (Note: We chose a 10-min eating period based on data from a prior experiment in our lab [18] where individuals who had not consumed any preloads ate ice cream ad libitum for a maximum of 10 min). The presentation of the preloads was randomized between participants.…”

“…The physical activity questionnaire (PAQ-M) cited was chosen because it was designed to capture the physical activity of daily living activities, as well as planned recreational exercise activities, and had been validated against the often-used Paffenbarger (PAQ-P) [22] Participants registered their hourly activity using 8 response categories for the 12-item questionnaire. The average hours/week of activity were calculated per Rubenstein [21] using "the midpoints of the eight response categories, i.e., 0 (none), 0.5 (<1), 1.5 (1-2), 4 (3-5), 7.5 (6-9), 14.5 (10)(11)(12)(13)(14)(15)(16)(17)(18)(19), 24.5 (20-29), and 35 (≥35)".…”

Approaches to Research in Art Therapy Using Imaging Technologies

“…Potential areas of inquiry using fNIRS could include examining positive emotions and reward perception through the dopaminergic pathways in the medial prefrontal cortex and the parietal cortex (Lambert, 2010; Hass-Cohen and Findlay, 2015). fNIRS also captures overall prefrontal cortex activation which can be used as a measure of executive function and self-regulation for disorders of addiction (Bunce et al, 2013), suicidality (Sargent et al, 2018), depression (Ma et al, 2017) and binge eating (Nasser et al, 2016). The role that the facilitated use of art media in art therapy sessions plays in executive control and emotion regulation can be examined further by tracking PFC activation using fNIRS.…”
