𝛿波

（从𝛿 波转戳到箇里）

𝛿波（英语：delta wave）是脑电波个一种，指频率处于 0.5 至 4 Hz 之间个脑电波，跟其他脑电波一样子，有得用脑电图个方法量度。伊是主要脑电波当中频率最低慨，一般都拨人认为反映一个冇啥活动个脑，是孲𤘅子个脑最常有个脑电波，而在正常个大人当中通常就会在非快速动眼睡眠个第三阶段－即是个人睏得最深哪时出现。

呢個腦電波喺1 秒之内有大约 4 个波，频率大约 4 Hz，属 Delta波。

伊个名出自希腊字母当中个「𝛿」。

概论

编辑
  • 跟其他脑电波一样，Delta 汳可以用脑电图（EEG）个方法探测得到。本来学界对 Delta 波个定义是「频率在 1 至 4 Hz 之间个脑电波」，但是近期个研究就有兴将个界限设在垃海「0.5 至 2.0 Hz」垃海。 Delta 波在古典脑电研究所描述个脑电波当中最低频慨，要去到廿一世纪头慨脑电研究先有尝试低频个脑电波－即是频率低到成0.1 Hz 以下个脑电波。
  • 在一个正常健全个大人身上，Delta 波一般要去到睏觉慨第三阶段当中先会出现，在嗰阵个脑仲有至少50% 个活动是高频过Delta 波，而去到第四阶段－只动物睏得最深啥段－个脑就基本上由Delta 波主导了，Delta 波个比例会超过50% 。已知全部个哺乳类动物都会喺睏觉哀时第四阶段经过了。
  • Delta 波跟 K-complex 箇种脑电现象有关：在睏觉个第三阶段，K-complex 还会在 Delta 波出现前出现。
