在从运动皮层记录的α功率的单次神经反馈训练之后，促进了手部运动序列的内隐学习（Ros等人，Biological Psychology 95：54-58，2014）。这种促进作用可能被应用于改善手部运动功能受损患者的康复结果。在目前的研究中，一组10名被诊断为脑瘫的患者训练了来自左右运动区记录的大脑活动的α功率的降低。训练分为三个阶段，每个阶段8分钟。在此期间，参与者用他们的非惯用手执行了一系列反应时间任务，总共五次。一周或更长时间后重复类似的程序，但这次训练是基于模拟大脑活动。在神经反馈训练后，参与者的反应时间比模拟训练后在每次连续跑步中下降得更快。还记录了两个3分钟的基线条件，一个是睁着眼睛，另一个是闭着眼睛，在实验阶段的开始和结束。神经反馈或模拟训练的α功率没有显着变化，并且与反应时间的减少没有相关性。为此，讨论了捐款。
Facilitation of implicit learning of a hand motor sequence after a single session of neurofeedback training of alpha power recorded from the motor cortex has been shown in healthy individuals (Ros et al., Biological Psychology 95:54-58, 2014). This facilitation effect could be potentially applied to improve the outcome of rehabilitation in patients with impaired hand motor function. In the current study a group of ten patients diagnosed with cerebral palsy trained reduction of alpha power derived from brain activity recorded from right and left motor areas. Training was distributed in three periods of 8 min each. In between, participants performed a serial reaction time task with their non-dominant hand, to a total of five runs. A similar procedure was repeated a week or more later but this time training was based on simulated brain activity. Reaction times pooled across participants decreased on each successive run faster after neurofeedback training than after the simulation training. Also recorded were two 3-min baseline conditions, once with the eyes open, another with the eyes closed, at the beginning and end of the experimental session. No significant changes in alpha power with neurofeedback or with simulation training were obtained and no correlation with the reductions in reaction time could be established. Contributions for this are discussed.
