Abstract： The human parental brain could be defined as is the network of regions that support caregiving behaviors to identify and react to infant related stimuli (infant vocals and facial expressions). First, we reviewed the neural circuits that were demonstrated to be involved in establishing and maintaining parent-infant relationships, which included circuits for motivation-reward, empathy, emotion regulation and executive function. And the important brain areas incorporate the orbitofrontal cortex, anterior cingulate cortex, anterior insula, amygdala, and supplementary motor area. Second, the current review summed that human parental brain is sensitive to multiple parenting determinants, including parenting abilities, parental hormones and psychopathology. The growth of parenting abilities and the improvement of oxytocin levels are beneficial to the processing for infant stimuli. Finally, several advices were proposed for future directions: 1) prospective and longitudinal studies across important transition periods for parenting; 2) describing the neural basis of male psychopathologies and exploring targeted interventions and treatments; 3) employing some advanced neuroscience technique (e.g., hyper scanning) to highlight the simultaneous neural activity between mother and father or parents and infants; and 4) conducting parental brain research in Chinese culture.

Abstract： The integration of various emotional information from different modalities (e.g., face and voice) plays an important role in our interpersonal communication. In order to understand its brain mechanism, more and more researchers found that the interaction between facial expression and vocal emotional information begins in the early stage of perception, and the integration of emotional information content occurs in the late decision-making stage. In the early stage, the primary sensory cortex is responsible for encoding information; while in the late stage, the amygdala, temporal lobe and other advanced brain regions are responsible for cognitive evaluation. In addition, the functional coupling of oscillation activities on multiple frequency bands facilitates the integration of emotional information cross channels. Future research needs to explore whether facial expression and vocal emotional information integration is associated with emotional conflict, and whether inconsistent emotional information has advantages. Lastly, we should find out how the neural oscillations of different frequency bands promotes the integration of facial expression and vocal emotional information, so as to further understand its dynamic basis.

Abstract： How to reveal the cognitive neural correlates underlying emotional face processing has always been the popular topic for psychology and social neuroscience. Previous studies mainly used single facial expressions as the stimuli to induce and present emotions, but there is still a lack of attention and the investigation for the crowd emotion. Thus, the present project plans to reveal the neural correlates underlying the processing of crowd emotional faces through the combination of behavioral, ERP, fMRI, and TMS experiments, in which the emotional information (valence and intensity), face direction (frontal, lateral and inverse view), integrity (partial presentation, complete presentation) and spatial frequency (complete, high frequency, low frequency) will be investigated to reveal the temporal dynamics and brain activation patterns of the processing of crowd facial expressions. Finally, our work will be expected to beneficially serve the comprehensive understanding of the nature of the perception and recognition of crowd emotion, which is also of practical significance towards updating social interactions.
