Electrical stimulation of the human epileptic brain is used mainly for identification of eloquent cortical regions such as motor and speech areas. Other stimulation responses include the patient's epileptic auras and seizures. In addition, experiential phenomena may be elicited. Here we describe the reproducible initiation of a structured complex visual hallucination on stimulation of the left lateral occipital cortex (superior part of Brodmann area 19, close to the angular gyrus of the parietal lobe). Our findings illustrate that stimulation of the left temporo-parieto-occipital junction may activate networks of visual perception (color, pattern, movement, rotation, shape, and memory) independent of the cortical hierarchy from elementary to complex information.
对人类癫痫脑区进行电刺激主要用于识别明确的皮质区域，如运动区和言语区。其他刺激反应包括患者的癫痫先兆和发作。此外，还可能引发体验现象。在此，我们描述了刺激左侧枕叶皮质（布罗德曼19区上部，靠近顶叶角回）时可重复性地引发一种结构化的复杂视幻觉。我们的研究结果表明，刺激左侧颞顶枕交界区可能激活视觉感知网络（颜色、图案、运动、旋转、形状和记忆），而与从基本信息到复杂信息的皮质层级无关。
