Excretion of noradrenaline and adrenaline was investigated in two experiments which included 3 physical test sessions and 3 mental test sessions (Experiment X) and a week of real-life situations (Experiment Y). An increased excretion of both catecholamines was found during each test in Experiment X. The noradrenaline excretion discriminated well between(More)
Electroconvulsive shock given to rats immediately after one-trial avoidance learning produced a significant amnesic effect 24 hours later; this amnesia had largely disappeared in further retention tests 48 and 72 hours after treatment. This result puts in question a basic assumption implicit in most memory consolidation studies that such amnesic effects(More)
Parietal pericardial lymphatics were visualized by indirect and direct India ink injections in 35 human cadavers. Studies included examination of cleared specimens under the dissecting microscope and standard light microscopy. The lymphatic vessels of the ventral pericardial surface most often pass along the phrenic nerves cranially to terminate in the(More)
T HIS WORK was undertaken on the hypothesis that endomyocardial fibrosis or eudocardial fibroelastosis, or both, might be produced by chronically interrupting cardiac lymph flow. This concept developed from the fact that significant fibrosis occurs in areas of the body where substantial obstruction to lymph drainage occurs. Some knowledge of the anatomy of(More)
