Cortical Dynamics Subserving Visual Apparent Motion
Motion can be perceived when static images are successively presented with a spatial shift. This type of motion is an illusion and is termed apparent motion (AM). Here we show, with a voltage sensitive dye applied to the visual cortex of the ferret, that presentation of a sequence of stationary, short duration, stimuli which are perceived to produce AM are, initially, mapped in areas 17 and 18 ...
متن کاملThe Cortical Topography of Visual Evoked Potentials Elicited by Chromatic and Luminance Motion
When motion-onset VEPs are elicited by moving luminance patterns, the motion specific component of the response, N2, is more prominent at electrode sites that overlay the lateral occipito-parietal cortex close to area V5/MT, than over the primary visual cortex. Functional segregation suggests that colour and motion processing should take place along different ventral occipito-temporal and later...
متن کاملThe relationship of visual evoked potentials to cortical physiology.
The last 15 years have seen a rapid expansion in studies on human visual evoked potentials (VEP), both a t the fundamental and at the clinical level. A wide variety of stimulus conditions have been explored,’ new types of mathematical tools have been i n t r o d ~ c e d , ~ . ~ and there has been an increasing appreciation of possible VEP correlates with underlying physiological mechanisms!

متن کاملTopographical analysis of motion-triggered visual-evoked potentials in man.
PURPOSE The middle temporal (MT) area of the cortex of the monkey is involved in visual motion analysis. Previous studies using brain-imaging techniques have shown that the area around the anterior occipital cortex in man is homologous to the area MT of the monkey. In this study, we investigated the cortical components of motion-triggered visual evoked potentials and their topography in the vis...
متن کاملControl of humanoid robot via motion-onset visual evoked potentials
This paper investigates controlling humanoid robot behavior via motion-onset specific N200 potentials. In this study, N200 potentials are induced by moving a blue bar through robot images intuitively representing robot behaviors to be controlled with mind. We present the individual impact of each subject on N200 potentials and discuss how to deal with individuality to obtain a high accuracy. Th...
