A method for displaying fixed or time-varying textured patterns under computer control is described. The luminance profiles of these patterns is fixed in one dimension (Y axis), but can be arbitrarily complex in the other dimension (X axis) since they are synthesized by software. An example of the use of the method in texture matching experiments is given.  相似文献

The construction of a simple thermistor respiration-transducer support assembly, which allows the monitoring of respiration in human subjects without the discomfort often associated with more traditional attachment methods, is described.  相似文献

Regional cerebral glucose metabolism in aphemia: A case report   总被引:1,自引:0,他引:1  
Local cerebral metabolism was determined in a patient suffering aphemia following cerebral infarction using the 18FDG-PET technique. The syndrome was characterized by profound ictal nonfluency with sparing of other language functions. Speech subsequently improved so that content and grammar were appropriate but mild dysprosody persisted. Conventional CT showed no lesion of the left hemisphere while PET revealed a discrete focus of hypometabolism on the left which partially resolved on serial studies. The metabolic lesion could be localized to the region of the inferior precentral gyrus and the adjacent subcortical space.  相似文献

Adult male and female southern grasshopper mice (Onychomys torridus) were tested for predatory aggression toward cricket prey 1 hr after single injections of d-amphetamine (1 or 10 mg/kg) or 1-amphetamine (1 or 10 mg/kg). At the lower dose, d-amphetamine decreased feeding behaviors, while I-amphetamine altered attack-related behaviors. At the higher dose, both stereoisomers appeared to be equipotent in significantly decreasing 5 measures of predatory aggression. These results suggest that brain dopamine and norepinephrine play important roles in the regulation of predatory aggression of Onychomys torridus.  相似文献

A study of 379 violent incidents between pairs of psychiatric inpatients during an eight-month period indicates a substantial number of patterned associations between assaulting patients and those struck. In addition, regularities are observed in these incidents between frequency of occurrence and spatiotemporal and other contextual factors. Taken in the aggregate, these relationships support enlargement of most current conceptualizations of the violent act in psychiatric settings, which focus almost exclusively upon physiologic and psychologic state changes within the identified initiator of violent acts.  相似文献

Lois C. Dubin 《Jewish History》2012,26(1-2):201-221
This article examines modern Jewish doctors and the Enlightenment in action through its analysis of Dr. Benedetto Frizzi (1756–1844) as an Enlightenment Jewish physician and public intellectual in Habsburg northern Italy. Frizzi sought to spread the new Enlightenment gospel of polizia medica—public health policy or social medicine—that he learned from its pioneering exponent, Dr. Johann Peter Frank, his teacher at the University of Pavia. Frizzi dispensed Enlightenment medicine for the benefit of the state and society in general, as well as Jewish society and culture in particular, for he saw himself as both public health crusader and doctor-priest ministering to his own people. His commitments to Enlightenment science and rationalism led him to criticize Jewish social practices harshly even as he creatively reinterpreted classic Jewish texts; accordingly, Frizzi was regarded in some quarters as subversive, while in others as an apologetic defender of Jews and Judaism. Situating Frizzi within the traditions of Jewish as well as European Enlightenment physicians, this article raises broader questions about religion and secularism in the modern discourse of medicalized Judaism.  相似文献
