Oscillatory and Non-Oscillatory Synchronizations in the Visual Cortex of Cat and Monkey

摘要: Our visual system can associate parts of a figure into perceptual whole if minimal feature contrast the against background is present, and certain rules Gestalt properties are fulfilled. It is, for example, easy us to recognize triangles in 1 even though they presented only as parts. Such type association does not require previous knowledge figure. The from its pre-attentively (“bottom-up”) acting process. In contrast, Dalmatine dog 2 be discovered quickly easily one already familiar with picture. Here, difficulty preattentive due complexity figure, discovery made more difficult by similarity features background. Feature recognition, this case, requires memory or other “top-down” support.
