    Alternating Predictable and Unpredictable States in Data From Cat Visual Cortex

    Visual inspection of data from cat visual cortex reveals, that the recently discovered 50-Hz-oscillations do not consist of a permanent oscillatory signal during the whole period of stimulation, but instead di...

    Field Discontinuities and Islands in a Model of Cortical Map Formation

    The existence of field discontinuities, i.e. discontinuities in cortical maps of the retina is well established by neurophysiological investigations in a variety of species [1–4]. In cat, additional geometric ano...

    A Cortical Interpretation of ASSOMs

    Self-organizing maps have been successfully used to model map formation in the visual cortex of mammals. When applying natural images as stimuli, properties of the maps obtained for low-dimensional input manif...

    Analysing the Context Dependence of Receptive Fields in Visual Cortex

    Stimuli outside the classical receptive field of orientation-selective cells in the visual cortex can strongly modulate the response properties of these cells. Normally, stimuli with orientation contrasts lead...
