The 1996 feed ban reduced but did not eliminate BSE in France, with only two late-stage infected animals under 30 months old expected to be slaughtered for consumption. A summary of robust cohort-based epidemiological analyses is recommended for re-evaluating the risks of consuming beef from countries with native-born BSE cases. Christl A. Donnelly is at the Department of Infectious Disease Epidemiology, Imperial College School of Medicine, London. She has published several studies on BSE and vCJD, including models for epidemics.

The study shows that auditory stimuli can alter visual perception, creating a visual illusion where a single flash is perceived as multiple. This illusion is selective and depends on the type of stimulus. The timing of visual and auditory stimuli affects the illusion, with the effect declining after 70 milliseconds of separation. The illusion is consistent with the integration time of polysensory neurons in the brain. The study challenges the notion that vision dominates multisensory perception, showing that auditory information can qualitatively alter the perception of an unambiguous visual stimulus. The illusion was tested with various conditions, and results showed that the illusion persisted even when subjects were aware of the actual stimulus. The influence of auditory cues on visual perception has been demonstrated in other studies, but this study extends previous findings by showing that sound can qualitatively alter visual perception even when the visual stimulus is not ambiguous. The illusion is robust to variations in many parameters, indicating a fundamental property of polysensory mechanisms in the brain.
