Imaging the brain at multiple scales: how to integrate multi...
Emotive EEG headsets
In the lab, students have access to 6 Emotiv Epoc neuroheadsets. These wireless devices are equipped with 16 'wet' EEG sensors and are designed to make performing brain research straightforward and accessible to a larger public than this sensitive and expensive technology has been so far. Moistening the felt sensor pads with saline and setting up the headset for a good signal only takes about 10 minutes, and then you're ready to do your experiment.
The sensor locations used by the Emotiv Epoc are a selection from the well-known 10-20 standard of sensor locations, supplemented with 2 locations from the 10-10 standard.
Mirametrix Eye tracker
In addition to EEG headsets the Beta lab has a fast and easy to setup Mirametrix eye tracker. The S1 Eye Tracker is a small USB device that takes less than a minute to setup. The eye tracker equipment sits unobtrusively below the monitor, facing the user. It uses advanced computer vision algorithms to track the eyes and produce point of gaze data at a rate of 60 times per second.
The small and light hardware package makes the eye tracker system easily portable between machines or locations. The fact that it does not require a custom monitor or embedded computer allows it to run entirely on existing hardware, keeping costs down and allowing the flexibility of monitor choice.
The 'Nexus-10' is a multifunctional physiometry device by Mindmedia that is specifically targeted at an audience interested in neurofeedback/biofeedback. It can record heart rate, respiration, skin conductance, blood flow, temperature and several other measures, and comes with a big software package to organize and record sessions with.
