EEG (electroencephalography) is the measurement of electrical potential differences across points on the scalp...
Neuronal activity in the brain gives rise to transmembrane currents that can be measured in the extracellular medium. Although the major contributor of the extracellular signal is the synaptic transmembrane current, other sources — including Na+ and Ca2+ spikes, ionic fluxes through voltage- and lig...

Electroencephalogram (EEG) measures the neuronal activities in the form of electric currents that are generated due to the synchronized activity by a group of specialized pyramidal cells inside the brain. The study presents a brief comparison of various functional neuroimaging techniques, revealing the ...
例如,一种基于ICA的联合方法融合了多模态EEG和fMRI数据,可以在没有ERP振幅或相位的先验信息情况下将单试次EEG和fMRI结合起来。在这种方法中,单试次EEG响应和fMRI响应可以合并到一个矩阵中,并进行联合时空分解。另一种方法是使用ICA源来融合EEG+fMRI数据。该方法还结合了约束和基于滞后的信号分解方法来演示电生理信号...

The EEG machine was first introduced to the world by Hans Berger in 1929. Berger, who was a neuropsychiatrist from the University of Jena in Germany, used the German term elektrenkephalogramm to describe the graphical representation of the electric currents generated in the brain. He suggested...

Yes, EEG headsets are generally safe to use. They are non-invasive devices that measure the electrical activity of the brain without emitting any radiation or electrical currents back to the brain. In clinical settings, EEGs have been used for decades to diagnose and monitor neurological condition...
Take a look at the logic behind event-related EEG studies: 1. There is continuous and ongoing EEG activity as well as random noise completely unrelated to the onset of a stimulus continually occurring. This is your “default activity“ (your ongoing thoughts and mental states). When you prese...
