    "title": "Modeling Globabl Synchrony in the Visual Cortex by Locally Coupled Neural Oscillators",
    "subtitle": null,
    "abstract": "A fundamental aspect of perception is to bind spatially\nseparate sensory features, essential for object\nidentification, segmentation of different objects, and\nfigure/ground segregation. Theoretical considerations\nand neurophysiological findingspoint to the temporal\ncorrelation of feature detectors as a binding mechanism.\nIn particular, it has been demonstrated that the cat visual\ncortex exhibits 40-60 H z stimulus-dependent\noscillations, and synchronization exists in spatially\nremote columns (up to 7 m m ) which reflects global\nstimulus properties (Gray et al., 1989; Eckhom et al.,\n1988). What neural mechanisms underlie this global\nsynchrony? Many neural models thus proposed end up\nrelying on global connections, leading to the question\nof whether lateral connections alone can jwoduce remote\nsynchronization. With a formulation diffwent from the\nfrequently used phase model, w e find that locally\ncoupled neural oscillators can indeed yield global\nsynchrony. The model employs a previously suggested\nmechanism that the efficacy of the connections is\nallowed to change on a fast time scale. Based on the\nknown connectivity of the visual cortex, the model\noutputs closely resemble the experimental findings.\nThis model lays a computational foundation for Gestalt\nperceptual grouping.",
