Bram 计算机接口 (BCI) 技术可以为患有严重运动障碍的人提供更大的独立性和更高的生活质量。 BCI 系统获取记录的大脑信号并将其转化为实时动作，以改善沟通、运动或感知。四名临床需要颅内皮层电图检查 (ECoG) 的患者参加了这项研究。参与者接受了多次训练，使用运动和/或听觉意象来调节他们的大脑信号，以控制计算机光标的移动。在运动和/或感觉区域放置电极的参与者能够在 2 至 7 天的训练中实现光标控制。这些发现表明，之前被认为不适合基于 ECoG 的控制的感觉和其他大脑区域可以提供可能对运动 BCI 有用的额外控制通道。
Bram-Computer interface (BCI) technology can offer individuals with severe motor disabilities greater independence and a higher quality of life. The BCI systems take recorded brain signals and translate them into real-time actions, for improved communication, movement, or perception. Four patient participants with a clinical need for intracranial electrocorticography (ECoG) participated in this study. The participants were trained over multiple sessions to use motor and/or auditory imagery to modulate their brain signals in order to control the movement of a computer cursor. Participants with electrodes over motor and/or sensory areas were able to achieve cursor control over 2 to 7 days of training. These findings indicate that sensory and other brain areas not previously considered ideal for ECoG-based control can provide additional channels of control that may be useful for a motor BCI.
