    Notes: Summary Monkeys wore either base-out prisms to promote changes in tonic vergence or periscopic spectacles to promote changes in the coupling between accommodation and vergence. Eye movements were recorded using the magnetic search coil technique and the monkeys were rewarded for accurate fixation. Two normal monkeys and two monkeys which had previously received lesions of the flocculus and ventral paraflocculus were studied. After 30 min of prism viewing the two normal monkeys had elevated phoria — increased by approximately 50% of the prism stimulus. The two lesioned monkeys also had phoria increases of a similar size after prism viewing. The effect of duration of prism viewing on the magnitude and time course of phoria elevation was studied in one normal monkey. The initial magnitude of phoria elevation and the time constant of relaxation of phoria both increased as the duration of prism exposure varied from 5 s to 30 min. Initial phoria increased approximately in proportion to the logarithm of duration of prism exposure whereas the time constant of phoria relaxation increased linearly with duration. In the same normal monkey it was shown that increasing vergence by means of accommodative-vergence did not induce phoria changes. The effect of periscopic spectacle viewing was studied in all four monkeys. After 30 min of periscopic spectacle viewing all four monkeys had a higher AC/ A ratio. The magnitude of the changes was (paradoxically) greater in the two lesioned monkeys than in the one normal monkey studied fully. The increases in AC/A ratio were moderately persistent, relaxing back to control values with time constants (in the lesioned monkeys) of the order of two hours.

    Notes: [Auszug] THERE is currently considerable enthu-siasm for 'neural network' models of brain function, but one issue that has not been resolved is how the structure of real brain circuits (which are by no means always the densely randomly in-terconnected networks favoured by the theoretical network modellers) ...

    Notes: [Auszug] MOTION of an observer creates 'optic flow' of the retinal image, containing information both about the observer's motion (or rather the motion of his eye) and about the three-dimensional structure of the world, as Gibson1 was the first to emphasize. Although optic flow is purely a matter of ...
