摘要

我们的初步行为实验表明，当被试对重复呈现的视觉刺激作出反应时，反应时间缩短。一种可能的解释是，大脑预先激活了负责刺激处理的神经系统。如果是这样，在实验之前激活这些区域可能会立即减少响应时间，为令人兴奋的实际应用开辟道路。为了测试这个机会，我们在受试者开始执行感知决策任务之前应用经颅磁刺激(TMS)。通过比较经颅磁刺激组和对照组的反应时间，我们观察到一个显著的变化，证实了我们的假设。

Anterior TMS Speeds up Responses in Perceptual Decision-making Task

Our preliminary behavioral experiments suggest that the response time decreases when subjects respond to the repeatedly presented visual stimuli. A potential explanation is that the brain preactivates neural ensembles responsible for stimulus processing. If so, activating these areas before the experiment may reduce the response time immediately, opening ways for exciting practical applications. To test this opportunity, we apply transcranial magnetic stimulation (TMS) before the subjects start performing a perceptual decision-making task. Having compared the response time between the TMS and control groups, we observed a significant change confirming our hypothesis.
