Document Summary
An unpleasant sensory and emotional experience associated with actual or potential tissue damage or described in terms of such damage . Pain can only be quantified by the person themselves. So difficult to know what pain babies are experiencing. Can try and quantify facial expressions e. g. brow bulge, eye squeeze. Darwin identified examples of human emotional expression that are easily recognised in other primates, and domestic animals. An emotion constitutes an internal, central (as in central nervous system) state, which is triggered by specific stimuli (extrinsic or intrinsic to the organism) Darwin associated animal expressions with similar human expressions. Emotion is a state of the cns triggered by specific stimuli that impacts on organism. There is opposition of emotional behaviours as determined by pleasantness and arousal. Human infants show an innate happy reaction to sweet taste (protrude tongue), as do other animals. Can measure facial expressions in mice that correspond to pain.
