Cognitive Potentials of the Male Brain Evoked by Perceivinghuman's Faces With Different Emotional Modalities

Abstract

The calculation of the difference in peaks of the event-related potential in men during exposure to different-sex faces with differential emotional modality using the MATLAB and EEGLAB software packages. The electrical activity of the brain of 20 male students of Taras Shevchenko Kyiv National University was recorded to identify the difference in the activation of brain structures during the demonstration of portraits of different sexes with positive and negative emotional modalities. Statistically significant differences in peak amplitude were recorded for components N250, N400, and P300 when subjects were presented with male and female portraits with a positive emotional modality, while when exposed to a series of images with a negative emotional modality, no statistical differences were registered in any of the componenStatistically significant differences in the peak amplitude were recorded for the N250, N400, and P300 components when subjects were presented with male and female portraits with a positive emotional modality, while when exposed to a series of images with a negative emotional modality, no statistical differences were registered in any of the components.
