Mid-latency auditory evoked potentials (MLAEPs) were assessed in 60 participants during 4 mental states described in traditional yoga texts. These 4 mental states are random thinking, nonmeditative-focused thinking, meditative focusing, and meditation. Assessments were made before (5 minutes), during (20 minutes), and after (5 minutes) each of the 4 states, on 4 separate days. There were prolonged latencies of 2 MLAEPs components, the Na and Pa waves during meditation (P < .05, post hoc analyses following analysis of variance [ANOVA]), suggesting that auditory information transmission at the level of the medial geniculate and primary auditory cortex (ie, the neural generators corresponding to the Na and Pa waves) was delayed. Hence, meditation influenced MLAEPs, while meditative focusing did not.
在传统瑜伽文献中描述的 4 种心理状态下,对 60 名参与者进行了中期听觉诱发电位(MLAEPs)评估。这 4 种心理状态分别是随机思维、非冥想专注思维、冥想专注和冥想。在 4 天内,分别在 4 种状态之前(5 分钟)、期间(20 分钟)和之后(5 分钟)进行了评估。在冥想期间,2 个 MLAEP 成分 Na 和 Pa 波的潜伏期延长(P <.05,方差分析[ANOVA]后的事后分析),这表明内侧膝状体和初级听觉皮层(即对应于 Na 和 Pa 波的神经发生器)水平的听觉信息传递被延迟。因此,冥想影响了 MLAEPs,而冥想专注则没有。
