During intracellular iontophoretic injection of Ca(++) into Limulus ventral photoreceptor cells, there is a progressive diminution of the light response. Following Ca(++) injection, the size of the light response slowly recovers. Similarly, there is a progressive diminution of the light response during intracellular injection of Na(+) and recovery after the injection is stopped. The rate of dim...

The ability to predict an impending threat during Pavlovian conditioning diminishes the emotional response that is produced once the threat is encountered. Diminution of the threat response appears to be mediated by somewhat independent associative learning and expectancy-related processes. Therefore, the present study was designed to better understand the neural mechanisms that support associa...

L’obCsitC, pathologie frtquente dans les sociCtCs industrialiskes, est caractQiste par un sur-diveloppement du tissu adipeux. Nous avons CtudiC un moditle animal d’obksitk, le rat Zucker gCnCtiquement obkse. D b l’iige de 30 jours, les cellules adipeuses des rats mutants transportent beaucoup plus de glucose que celles des temoins normaux des memes portCes. Cette anomalie repose sur une augment...

Introduction: To evaluate a case of bilateral diminution vision with metamorphopsia and hyperdeviation. This is retrospective descriptive study data was gathered from series questionnaire investigative analysis. Case Report: A 27-yea

The time-course of light-induced changes in membrane voltage and resistance were measured in single photoreceptors in eyecup preparations of Gekko gekko. A small circular stimulus directed toward the impaled receptor produced membrane hyperpolarization. Application of a steady annular light to the receptor periphery resulted in diminution of the receptor's response to the stimulus. The effects ...
