My main objective is to decode high level brain signals for decision making and planning, and their integration, by using electrocorticographic (ECoG) signals in monkeys. During the project duration, we successfully implanted 128-channel ECoG arrays in monkeys, covering the widest area that had been reported. We also established a novel ECoG-based decoding system and demonstrated that ECoG signals carry rich information for high-dimensional intended movements, visual and auditory processing, and high-level cognitive functions, such as social reasoning.

我的主要目标是解码高层次的决策和计划，以及他们的整合，通过使用脑皮层电（ECoG）信号在猴子的大脑信号。在项目期间，我们成功地将128通道ECoG阵列植入猴子体内，覆盖了已报道的最广泛区域。我们还建立了一个新的基于ECoG的解码系统，并证明了ECoG信号携带丰富的信息，用于高维预期运动，视觉和听觉处理以及高级认知功能，如社会推理。
