In the mammalian cerebral cortex, each sensory cortex plays a central role in the information processing of each sensory modality, yet the cross-modal interactions between sensory cortices remains to be elucidated. Herein, we designed a surface electrode array with 32 recording sites and established a novel electrophysiological technique to record neural activities simultaneously from the auditory and visual cortices of anesthetized rats. We evaluated our mapping in two ways; first, the middle-latency potentials in the auditory-evoked potentials and visual-evoked potentials were localized in the auditory and visual cortex, respectively. Second, the microelectrode array successfully recorded auditory and visual mismatch negativity (aMMN and vMMN), which is one of the neural activities reported to reflect cross-modal interactions in previous human studies. In addition, we demonstrated that MMN distributed beyond the border between these sensory cortices, suggesting cross-modal interactions between these areas. Taken together, the present recording technique will contribute to elucidating cross-modality information processing in sensory cortices.

大鼠听觉和视觉皮层神经活动的同步映射
在哺乳动物大脑皮层中,每个感觉皮层在每种感觉模式的信息处理中都起着核心作用,但感觉皮层之间的跨模式相互作用仍有待阐明。在此,我们设计了一个具有 32 个记录位点的表面电极阵列,并建立了一种新的电生理技术来同时记录麻醉大鼠听觉和视觉皮质的神经活动。我们以两种方式评估我们的映射;首先,听觉诱发电位和视觉诱发电位的中潜伏电位分别位于听觉皮层和视觉皮层。其次,微电极阵列成功记录了听觉和视觉错配负性(aMMN和vMMN),这是在以前的人类研究中报告的反映跨模式交互的神经活动之一。此外,我们证明 MMN 分布在这些感觉皮层之间的边界之外,表明这些区域之间存在跨模式交互。总之,本记录技术将有助于阐明感觉皮层中的跨模态信息处理。
