Abstract

Gezichtsbedrog biedt een venster op de werking van de hersenen omdat het onderliggende waarnemings-mechanismen kan onthullen op een manier die niet mogelijk is tijdens waarheidsgetrouwe waarneming. Hier wordt getoond hoe een klassiek voorbeeld van gezichtsbedrog inspiratie geeft voor de ontwikkeling van een hersenmodel voor drie- dimensionale waarneming. Zulke modellen kunnen tal van praktische toepassingen vinden in de geneeskunde, luchtvaart en robotiek.

Abstract

To determine whether preoperative ketoprofen and mesosalpinx infiltration, either alone or in combination, favorably influence postoperative recovery after outpatient laparoscopic sterilization.In a double-blind, randomized, placebo-controlled study, 20 women received 100 mg of oral ketoprofen preoperatively, and each mesosalpinx was infiltrated with 5 mL of saline plus epinephrine 1:200,000; 20 women were given oral ketoprofen, and each mesosalpinx was infiltrated with 5 mL of bupivacaine 0.5% with epinephrine 1:200,000; and 20 women received a placebo capsule with mesosalpinx infiltration. Pain was assessed by a visual analogue scale and a self-assessment 11-point scale; outcome was assessed by discharge time, consumption of analgesics, incidence of nausea and vomiting, and the number of postoperative days to full recovery.Pain ratings in the ketoprofen-only group were significantly higher than in the two other groups (P.001). Preoperative ketoprofen alone provided insufficient postoperative pain relief, necessitating the use of opiates and peripheral analgesics. Nausea and vomiting were highest in these subjects, as was intake of peripheral analgesics at home. Times to discharge were also the longest in this group (median 385 minutes, range 260-510) and differed significantly from both other groups (P.001). It took 4-13 days to recover. In contrast, women with only a mesosalpinx block ambulated and recovered sooner, but times to discharge were still prolonged (median 240 minutes, range 105-375). Recovery usually occurred by the fourth postoperative day. The combination of preoperative ketoprofen and mesosalpinx block resulted in the shortest times to discharge (median 190 minutes, range 80-330), the least consumption of peripheral analgesics, and the lowest incidence of nausea and vomiting. Recovery occurred by the fourth postoperative day.Mesosalpinx infiltration has a favorable effect on postoperative recovery after day-surgery laparoscopic sterilization. Still better results can be obtained with a multimodal analgesic approach, combining mesosalpinx infiltration with preoperative ketoprofen.

Abstract

Contains fulltext : 218346.pdf (publisher's version ) (Closed access), The spatial differences between the two retinal images, called binocular disparities, can be used to recover the three-dimensional (3D) aspects of a scene. The computation of disparity depends upon the correct identification of corresponding features in the two images. Understanding what image features are used by the brain to solve this binocular matching problem is an important issue in research on stereoscopic vision. The role of colour in binocular vision is controversial and it has been argued that colour is ineffective in achieving binocular vision. In the current experiment subjects were required to indicate the amount of perceived depth. The stimulus consisted of an array of fronto-parallel bars uniformly distributed in a constant sized volume. We studied the perceived depth in those 3D stimuli by manipulating both colour (monochrome, trichrome) and luminance (congruent, incongruent). Our results demonstrate that the amount of perceived depth was influenced by colour, indicating that the visual system uses colour to achieve binocular matching. Physiological data have revealed cortical cells in macaque V2 that are tuned both to binocular disparity and to colour. We suggest that one of the functional roles of these cells may be to help solve the binocular matching problem.
