This paper is about frisson, the sensation of having a physical reaction in response to aesthetic stimuli. This reaction is not common and occurs from the result of activation to the amygdala and hypothalamus or activation to the sympathetic nervous system. However, it is also possible to experience frisson from stimuli perceived as negative. In this case, adrenaline is pumped through the body triggering the fight or flight response. This paper looks at a few examples of activation from stimulus that causes physical reactions in our body.
