Neuroscience Perspectives
Social and emotional stimuli, particularly those related to the well-being of another person, are being more directly studied with advent of technology that can track brain activity (such as Electroencephalograms and functional Magnetic Resonance Imaging). Amygdala and insula activation occur when a person experiences emotions, such as fear and disgust respectively. Primary motor regions are also activated during sympathy. This could be caused by humans' reaction to emotional faces, reflecting the expressions on their own faces, which seems to help people better understand the other person's emotion. In addition, researchers have also suggested that the neural mechanisms that are activated when personally experiencing emotions are also activated when viewing another person experiencing the same emotions (mirror neurons). Pain seems to specifically activate a region known as the cingulate cortex, in addition to activation that is mentioned earlier. The temporal parietal junction, orbitofrontal cortex, and ventral striatum are also thought to play a role in the production of emotion.
Generally, empathic emotions (including sympathy), require the activation of top-down and bottom-up activity. Top-down activity refers to cognitive processes that originate from the frontal lobe and require conscious thought whereas bottom-up activity begins from sensation of stimuli in the environment. From the sensory level, people must sense and experience the emotional cues of another. At the same time, indicative of the dual-process theory, top-down responses must be enacted to make sense of the emotional inputs streaming in and apply motive and environmental influence analyses to better understand the situation. Top-down processes often include attention to emotion and emotion regulation.
