Auditory Oddball

We adopted a roving oddball paradigm. The trains of repetitive tones of different frequencies were randomly presented. Epidural ECoG recordings were taken in the passive listening condition while monkeys were awake. ECoG data were sampled at 1KHz.

本研究采用漫游式偏差刺激范式（roving oddball paradigm）。将不同频率的重复音调序列随机呈现。在清醒猕猴处于被动聆听状态时，采集其硬膜外皮层脑电（Epidural ECoG）信号。该皮层脑电数据的采样率为1千赫兹。
