The prefrontal cortex has conscious and unconscious responses to social/emotional facial expressions involving sex, hemispheric bias and central heart regulation.

!---- passively viewing emotionally stimulating images can promote attention-oriented and activate neural circuitsthe subcutaneous and cerebral cortex pathways in the "social brain" network of individual development respond to visual stimuli for facial detection and recognition, facial expressions, eye appearance, and direct gazecan then integrate nerve signals into conscious emotional sensations and sensory experiencesemotions are also associated with memory, visceral responses, decision-making and behavioral displays the authors study NIRS's treatment of social/emotional facial expressions (i.e., conscious perception of different expressions (i.e., conscious perception of different expressions (neutral, happy, sad, angry, disgusted, and fear) and subconscious/blind negative expression perception (fear and disgust overlap with neutral emotions)the power spectrum analysis of the accompanying ECG signal reveals the intercom and para-intercom regulation of the heart responsemethod: After a neuropsychological assessment, 14 women and 14 men were examined using NIRS devices to collect PFC oxygenationparticipants are familiar with the test room and equipment to reduce the potential or real anxiety of the day of data collectionthey sit in comfortable chairs in temperature-controlled rooms (23 degrees C), hearing stimulation is limited, and there is no direct visual stimulation other than the computer screen in front of themduring this time, they listened to a neutral tone recording, providing instructions for the upcoming programimmediately after that, turn the 40 cm monitor on for 10 minutes to record "false baseline data"all procedures in theare completed in the 800-1200 hoursthen advise participants to continue their daily work before going to bedon the morning of Record Day, they were instructed to avoid all feelings of hunger or thirst by eating a light meal at least one hour before arriving at the lab, not drinking alcohol for the last time, caffeine or other light stimulants or sedatives for 24 hours, and not exercising for 12 hours before recordingresult: After consciously perceiving the smiley face, the value of HbO2 in the right PFC in women was higher than that of men, and the HbO2 value in the left PFC was higher than that of the malein men, when the expression of happiness is observed, the left PFC rises and the right PFC lowers HbO2cover up in two gendersThe HHb value during aversion performance was higher than the expression of fear, and the Post-Hidden Fear Performance HHb was higher than during the period of fearwhen women consciously and unconsciously deal with negative emotions, higher intercomandanding and lower parasensoric activities (LF/HF components) occur (in all cases, p.lt;0.05)these results showed that human PFC selectively activated cardiovascular responses based on gender, hemispheric bias, attention, and simultaneous central lysergic stimuli of conscious and unconscious emotional loadsoriginal link: Johari, Kand RBehroozmand, Event-related destruf of alpha and beta band oscillations squirt sym and limb srReebrain Research, 2020393: p112763.MedSci Original Source: MedSci Original, !-- Content Presentation Ends - !-- Determine signed-off-
