ElectroEncephaloGraphy (EEG)
We have 2 ElectroEncephaloGraphy, or EEG as we commonly call it, systems within the Psychology department. The latest is the Brain Vision actiCHamp Plus.
actiCHamp Plus at a glance:
- 64 channel GEL based system
- Scalable for high-density recordings
- Powerful lithium-ion battery pack
- Integration with EEGLAB, MATLAB®, LSL, OpenViBE
- Up to 100 kHz sampling rate
Our second system is made by EGI and utilises a saline solution, rather than gel.
EGI Geodesic at a glance
- 64 and 256 channel dense array options
- Dedicated Apple Mac Pro running Netstation
- Integration with EEGLAB, MATLAB, EPRIME
- Up to 8 kHz sampling rate
Participants wear the EEG net directly on their head and are attached to the specialist amp which communicates with a dedicated computer. Data is generally presented as waveforms which can then be analysed in various ways, but there are also topographical mapping techniques that give you a graphical representation of what is happening.
