Some extra information is support of these c...Hi, <br /><br />Some extra information is support of these claims<br /><br />1)The P300 wave studied in EEG test is a positively deflected wave that is observed when individuals reflect upon the a stimulus. It is not associated with physical attributes of the stimulus but with the subject's interpretation of it. For example in the oddball task, when a subject recognizes a different stimulus after a large number similar stimuli the "control participants" display a large P300 wave. Interestingly there is relatively good evidence that shows patients with schizophrenia have a less intense and later P300 wave. (This technique is used to distinguish diagnostically between control groups, Schizoaffective, disorder groups and schizophrenic groups. <br /><br />2) I think this post also reflects the physiological responses of organisms to stimuli. <br />In general organisms are programed to react to changes, not to absolute values of certain stimuli. <br /><br />Examples: Baroreceptor reflex and how it can "re-set" it self.<br /><br />Pain receptors (and threshold points)<br /><br />Visual cortical columns (detecting visual stimuli) (Specifically On and Off cells)<br /><br />3) Do you know if this information is being used during treatment with burn patients and dressing changes. I hope that the nurses and doctors are aware the "pull fast technique" would be CONSIDERABLY more painful than the "slow inching technique" when pulling off bandages."<br /><br />fingers crossed++Anonymousnoreply@blogger.com
