Psychophysiological Reactions to Infusions of a Mixture of Adrenaline and Noradrenaline

F rankenhaeuser , M. & J ärpe , G. Psychophysiological reactions to infusions of a mixture of adrenaline and noradrenaline. Scand. J. Psychol ., 1962, 3 , 21–29.—Psychophysiological reactions to a mixture of adrenaline and noradrenaline (average dose 6.99 + 6.99 μg/min.) given as a continuous intravenous drip for periods of about 40 min. were studied in 11 subjects. Control data were obtained from placebo infusions. The catecholamine infusions produced marked subjective and overt symptoms as well as changes in heart rate and blood pressure. These reactions were—on the whole—similar to those produced by infusions of adrenaline only. Time experience was also affected by the catecholamines in that more was retained of the previously perceived time intervals.
