4. Whole-body vibration elicits 40 Hz cortical gamma oscillations and ameliorates age-related cognitive impairment through hippocampal astrocyte synapses in male rats NSTL国家科技图书文献中心

Liu, Mingsong |  Li, Lei... -  《Biogerontology》 - 2025,26(1) - 共15页

摘要： oscil2lations at 40 Hz have been identified as a potential |  stimulation: whole-body vibration at 40 Hz. We examined the |  effects of 40 Hz vibration on cognitive performance and |  Hz, rather than 20 Hz or 80 Hz, elicited cortical |  implementation of 40 Hz whole-body vibration significantly
