Raw data, sheep visual decoding

Implantable neural interfaces enable recording of high-quality brain signals that can improve our understanding of brain function. This work examined the feasibility of using a minimally invasive endovascular neural interface (ENI) to record interpretable cortical activity from the visual cortex. A sheep model (n = 5) was used to record and decode visually evoked potentials from the cortex both with an ENI and a subdural electrode grid.

植入式神经接口（Implantable neural interfaces）可记录高质量脑信号，有助于加深我们对大脑功能的理解。本研究评估了采用微创血管内神经接口（endovascular neural interface，ENI）从视觉皮层记录可解读皮层活动的可行性。实验使用绵羊动物模型（n=5），分别通过ENI与硬膜下电极栅格，对皮层的视觉诱发电位进行记录与解码。
