Objective. Characterize the role of the beta-band (13–30 Hz) in the human hippocampus during the execution of voluntary movement. Approach. We recorded electrophysiological activity in human hippocampus during a reach task using stereotactic electroencephalography (SEEG). SEEG has previously been utilized to study the theta band (3–8 Hz) in conflict processing and spatial navigation, but most studies of hippocampal activity during movement have used noninvasive measures such as fMRI. We analyzed modulation in the beta band (13–30 Hz), which is known to play a prominent role throughout the motor system including the cerebral cortex and basal ganglia. We conducted the classic ‘center-out’ direct-reach experiment with nine patients undergoing surgical treatment for medically refractory epilepsy. Main results. In seven of the nine patients, power spectral analysis showed a statistically significant decrease in power within the beta band (13–30 Hz) during the re...

在执行任务期间人类海马体的 Beta 波段功率调制。

客观的。描述人类海马体中 β 频段（13-30 Hz）在执行随意运动过程中的作用。方法。我们使用立体定向脑电图 (SEEG) 记录了伸手任务期间人类海马体的电生理活动。SEEG 以前曾被用来研究冲突处理和空间导航中的 θ 频带（3-8 Hz），但大多数运动过程中海马活动的研究都使用非侵入性测量，例如功能磁共振成像。我们分析了 β 频段（13-30 Hz）的调制，众所周知，β 频段在整个运动系统（包括大脑皮层和基底神经节）中发挥着重要作用。我们对九名接受医学难治性癫痫手术治疗的患者进行了经典的“从中心向外”的直接接触实验。主要结果。在 9 名患者中的 7 名患者中，功率谱分析显示，在治疗期间，β 频段 (13-30 Hz) 内的功率出现了统计学上的显着下降。
