Abstract

The current study investigated whether the age of healthy adults could predict the peak gamma frequency and the peak amplitudes of VEP components (N1, P2). 49 healthy participants (aged between 19 and 52 years) underwent EEG recordings during a visual task eliciting clear gamma frequency oscillations and VEP activities. After eliminating noisy and outlier data, data from 41 participants were analysed using simple linear regression. The results indicated that age was a significant predictor of peak gamma frequency and the peak amplitude of VEP-N1 but not the peak amplitude of VEP-P2. Age was negatively associated with peak gamma frequency and the peak amplitude of VEP-N1. These findings support previous research indicating that ageing is associated with decreased cortical inhibition, highlighting the importance of GABA in maintaining cortical E-I balance.

年龄可预测视诱发电位的峰值频率和N1振幅。
本研究探讨了健康成人的年龄是否可以预测VEP成分(N1, P2)的峰频率和峰幅。49名健康参与者(年龄在19岁至52岁之间)在视觉任务期间进行脑电图记录,引发清晰的伽马频率振荡和VEP活动。在消除噪声和异常数据后,使用简单线性回归对41名参与者的数据进行分析。结果表明,年龄是VEP-N1峰频率和峰幅的显著预测因子,而不是VEP-P2峰幅的显著预测因子。年龄与VEP-N1的峰值频率和峰值幅度呈负相关。这些发现支持了先前的研究,表明衰老与皮层抑制能力下降有关,强调了GABA在维持皮层E-I平衡中的重要性。

期刊介绍: BMC Neuroscience is an open access, peer-reviewed journal that considers articles on all aspects of neuroscience, welcoming studies that provide insight into the molecular, cellular, developmental, genetic and genomic, systems, network, cognitive and behavioral aspects of nervous system function in both health and disease. Both experimental and theoretical studies are within scope, as are studies that describe methodological approaches to monitoring or manipulating nervous system function.
