Brain mapping in humans through the electroencephalogram (EEG) is a record of the electrical activity generated in the cerebral cortex, where the primary emotion Disgust is built. There are still no reports of studies that worked on this emotion with professional categories in parallel with the electroencephalography technique. Thus, the objective of this study was to compare the topographic brain mapping in situations of disgust among individuals in the exact sciences, humanities and health. Quantitative, observational and cross-sectional study, data collection was carried out in the neuroscience laboratory of the State University of Health Sciences of Alagoas. Graduated professionals with more than two years of experience were included in this research, a sample of 45 individuals, 15 from each area (health, humanities and exact sciences). A form with personal information was used and an EEG examination was performed, simultaneously with the presentation of disgust images. The analysis of the data obtained during the demonstration of the image related to animal disgust showed an increase in the power of the gamma rhythm in the AD, PE and PD regions in individuals in the health area, and also an increase in the gamma rhythm in the AD region in individuals in the area exact. In the presentation of the images of disgust due to contamination, an increase in the power of the gamma rhythm was observed in the AD and PD regions in individuals from the health area, an increase in the power of the gamma rhythm in the areas AE and AD in individuals from exact sciences, and an increase in the power of the gamma rhythm in the PD region in human subjects. In the presentation of the basic disgust images, an increase in the power of the gamma rhythm in the AE area was observed in individuals in exact sciences, and an increase in the power of the gamma rhythm in the AE area in individuals in the humanities area. Our study demonstrated that the cerebral cortex is activated differently in relation to different types of disgust and as a function of professional experience.
