这项研究提出了一种新型的256通道电极帽，该电极帽具有半柔性、多针状、干电极等特点，且有专门适用于hd-eeg的尺寸、针数和电极布局，集成了三种不同类型的电极类型，可在多毛发（长针）、少毛发（中针）和无毛（波形针）位置，轻松、可重复且舒适地 ...

EGI高密度脑电图（High-Density EEG）系统是一种先进的脑电监测技术，由Electrical Geodesics, Inc.（EGI）开发。 该系统采用高密度电极阵列，最高可达256个电极，能够实现更全面、精确的脑电活动记录。

2022年7月3日 · 新型干式hd-eeg帽有助于快速、无凝胶脑电图，显著降低了每次hd-eeg测量对耗材的生态和经济影响，是首个具有256个通道的干式hd-eeg系统。 我们的多参数研究为基于干式和凝胶式脑电帽在时间、频率和空间域多个信号特征方面的等效性提供了证据。

Linking headboxes together allows more than 500 channels to be recorded. A 256-channel Neuvo EEG system has four headboxes, with 272 channels in total. Faster sampling rates allow for more accurate sampling of the analog data being recorded.

2016年1月1日 · The 256-channel Geodesic Sensor Net is constructed to include improved electrode coverage over the entire head, including the cheek and the neck area (Fig. 3), with the goal of detecting activity from the basal brain regions (Holmes, 2008, Sparkes et al., 2009). Our study demonstrated that dEEG, even when using an atlas head model, is very ...

Using 32 to 256 electrodes evenly spaced over the entire scalp, cheeks, and back of the neck, Geodesic EEG provides dense and even sampling, allowing you to detect brain activity at high spatial resolution, without having to interpolate between widely spaced sensors.

In this thesis, I propose a platform to simultaneously record EEG and eye movement data by integrating 256-channel EEG and Eye Tracker devices together. Then a procedure is designed and tested to process the EEG and eye movement records.

A 256-channel SynAmps RT EEG system consists of four headboxes, with 280 channels in total. A fully isolated, programmable bipolar excitation supply is also provided capable of supplying up to +/- 10VDC at 100mA to external bridges or measurement devices. Maximum Sampling Rate: 20,000 Per Channel all channels driven
