比如在老鼠清醒的时候或者REM睡眠的时候,海马体会有一个theta波,频段是5-15Hz,现在普遍认为theta波跟海马体编码空间记忆、记忆时间顺序等有关。老鼠休息或者NREM睡眠的时候,会出现一种低频尖波或者慢波(sharp wave),sharp wave上面会带着一些高频震荡,叫sharp wave-ripple(尖波涟漪),这个波被认为跟记忆的巩固和重...

theta rhythm (redirected fromTheta waves) Thesaurus Medical Financial Encyclopedia theta rhythm n. A waveform on an electroencephalogram having a frequency of 4 to 8 hertz, recorded chiefly in the hippocampus of carnivorous mammals when they are alert or aroused. Also calledtheta wave. ...
EEG Measurement Electroencephalography (EEG) is the tool scientists use to capture and study theta brainwaves. It measures electrical activity in the brain, pinpointing how and when these waves occur. Through EEG, researchers can observe the brain's transition into theta state, providing insights in...
Groups of specialized cells in the brain, called neurons, communicate with each other through electrical impulses. The rhythms these impulses create are brain waves. We can detect brain waves through an electroencephalography test, or EEG.

EEG based wheelchair navigation for paralysis patients Likewise, no group effect was noted for percent time in which each frequency band was observed, except for a significantly greater percent of theta rhythm in the non-medium controls' group compared to MG (p = 0.035), at the post-communicati...
Electroencephalogram (EEG) signal is a highly random, complex and non linear in nature. The analysis of Electroencephalogram remains problematic due to the limited understanding of the signal origin. In spite of these shortcomings, the EEG is valuable tool to evaluate the overall cerebral activity. ...
