Emotion and facial expressionUploader: Graham 24 days ago Subscribe 4296
Facial expressions are a form of nonverbal communication. Even beyond the idea of eye contact, eyes communicate more data than a person even consciously expresses. Eye contact is another major aspect of facial communication. For example, a happiness-signaling neuron would fire more spikes if the emotion was extreme happiness, and fewer spikes if the emotion was mild happiness. The recognition of emotion may also utilize the occipitotemporal neocortex, orbitofrontal cortex and right frontoparietal cortices. At its deepest and most painful, it is a sensation of great spiritual anguish, often without any specific cause. Further, there may be technological implications, such as improving human-computer interaction systems. When looking at a face, brain cells in the amygdala fire electrical impulses or "spikes" in response. When asked to rate the funniness of cartoons after the experiment, the cartoons seemed funnier when the participated rated them with the pen in between their teeth.
