Modular organization is fundamental to cortical processing, but its presence is human association cortex is unknown. We characterized phoneme processing with 128-1024 channel micro-arrays at 50-200µm pitch on superior temporal gyrus of 7 patients. High gamma responses were highly correlated within ~1.7mm diameter modules, sharply delineated from adjacent modules with distinct time-courses and phoneme-selectivity. We suggest that receptive language cortex may be organized in discrete processing modules.
模块化组织是皮层处理的基础，但其在人类联合皮层中的存在尚不清楚。我们使用128 - 1024通道微阵列，以50 - 200微米的间距，对7名患者颞上回进行了音素处理特征分析。在直径约1.7毫米的模块内，高伽马反应高度相关，与具有不同时间进程和音素选择性的相邻模块有明显区分。我们认为，接受性语言皮层可能是由离散的处理模块组成。
