Enhancing perceptual performance by BMI

这项研究计划的目的是利用非侵入性脑成像（MEG和fMRI）来确定预测行为表现的神经过程。结合脑磁图和功能磁共振成像分析的结果显示显着的活动，在运动前皮层预测的行为表现在噪声识别任务的语音刺激发作前约100毫秒。在进行大脑扫描的同时驾驶飞机的实验表明，每次试验进行25到5秒的自发大脑活动预测了未来滑翔机的着陆性能。据推测，这种活动反映了在随后的试验中选择适当的行动计划，可以用来给受试者反馈，以调节未来的表现注意力的准备。

The goal of the research proposal was to determine neural processes that predict behavioral performance using non-invasive brain imaging(MEG and fMRI). The results of the combined MEG and fMRI analysis revealed significant activity in premotor cortex that predicted behavioral performance on a speech in noise identification task around 100 msec before stimulus onset. Experiments involved with piloting an airplane while undergoing brain scanning showed that the spontaneous brain activity proceeding each trial by 25 to 5 seconds predicted future glider landing performance. It is hypothesized that this activity reflects attentional preparation in selecting appropriate action plans in the subsequent trial that can be used to give feedback to the subject to modulate future performance.
