PURPOSE:Figure-ground segmentation is a fundamental task for biological and artificial visual systems.The visual figure is many multiples greater in size than the receptive fields/filters of early vis
PURPOSE:Human subjects are more sensitive to luminance decrements than luminance increments,as is evident by a lower threshold and shorter latency for dark stimuli.
PURPOSE:Under a noisy "cocktail-party" condition with multiple-people talking,listeners often ask the talker to repeat the attended sentence for their better recognition.
目的:目前科学研究已经在猴子的V2区发现了双眼视差相关的功能地图,可以精细区分物体深度。但是作为双眼信息融合的第一站——初级视觉皮层V1区,尽管有大量文献证明有双眼视差敏感神经元的存在,但尚未找到功能性响应的确切标志(功能柱)。方法:利用改进的随机点立体光栅作为视觉刺激,在猫的V1区进行了基于内源信号的大脑光学成像实验和单细胞神经电生理实验。
PURPOSE:When a line is flashed on a patterned disk rotating back and forth at its turnaround point,the perceived location of the line is often dramatically displaced,known as the flash grab effect (Ca
PURPOSE:Humans can process motion information unconsciously.Here,taking advantage of visual adaptation and continuous flash suppression paradigms,we investigated the neural mechanisms of unconscious m
PURPOSE:Visual scenes contain local and global properties.Numerous behavioral studies demonstrate that the global features are processed more rapidly than local features,namely global precedence effec
