CD BioSciences' Neuroimaging Centre is a research platform with multiple large research facilities at its core, providing enhanced neuroimaging services in multiple areas. We offer Electrical Geodesics Inc. (EGI) and Biosemi HD EEG-based neuroimaging solutions, please read on to find out more.
The Electrical Geodesics Inc. /Philips system (EGI; Eugene, Oregon) features 256-channel HydroCel caps recording at 1000 Hz. This system allows for easy setup of routine EEG in human participants using an electrolyte solution-based interface. EEG data can be corresponded with MRI data using the Geodesic Photogrammetry System, improving spatial identification of neural sources. The Biosemi ActiView system (Amsterdam, Netherlands) records 128 channels at 2048 Hz and uses a gel-based interface for recording. It features active electrodes which allow for amplification nearer to the source and corresponding high signal to noise ratio. Optional skin-contact electrodes can be used for artifact detection, referencing, or electromyography. The Biosemi also uses a 1080p LCD monitor (Cambridge Research Systems Display++) which allows for research suitable color and timing reproduction, and additionally removes the need to calibrate the monitor, normally a time-consuming process. This system is po
Our Neuroimaging facilities in MSS 300 feature 2 high density EEG systems. They work in a similar fashion to "traditional" EEG in that they measure microvoltage electricity related to superficial neural activity, but our systems cover a much larger area of the cortex, allowing for more simultaneous data collection and more complex analyses that require whole-head data. Although the number of channels is greatly increased, setup time is not burdensome as individual site locations don't need to be measured and scalp preparation is minimal. Our two systems differ in a few key details, but are both suitable for a diverse number of projects. They are each used by several labs and dozens of individual users, and in use for numerous techniques including traditional neural wave-based analyses, event-related potentials, steady-state visual evoked potentials, and time-frequency analysis.
