项目摘要
I developed a mesh-shaped electrode array for electrocorticogram recording with openings for small probes, such as microelectrode and optical fiber, to pass through in collaboration with a group lead by Dr. Suzuki at University of Tokyo. I implanted this ECoG array together with a penetrating microelectrode array into the macaque IT cortex, and simultaneous recorded visually evoked cortical potential and unit activities while the monkey performed a fixation task. Decoding analysis showed that classification of the stimulus category, such as face, facial view and species could be performed with similar performance level from both ECoG and multi-site unit recording. This result also indicated that postoperative penetration of multiple fine probes into the cerebral cortex from ECoG windows applicable without major damage to the cortical function. This result suggests promising application to simultaneous conduction of multisite stimulation with ontogenetics tools, such as channel-rhodopsin, and multi-site electrophysiological recording from behaving primate visual cortices.
我与东京大学铃木博士领导的团队合作,开发了一种用于皮层电图记录的网状电极阵列,其开口可供微电极和光纤等小探针通过。我将这种 ECoG 阵列与穿透性微电极阵列一起植入猕猴 IT 皮层,并在猴子执行固定任务时同时记录视觉诱发的皮层电位和单位活动。解码分析表明,ECoG 和多站点单元记录可以以相似的性能水平对刺激类别(例如面部、面部视图和物种)进行分类。该结果还表明,术后可从 ECoG 窗口将多个细探针穿透到大脑皮层,而不会对皮层功能造成重大损害。这一结果表明,使用个体遗传学工具(例如通道视紫红质)同时传导多位点刺激以及灵长类行为视觉皮层的多位点电生理记录具有广阔的应用前景。
