4. Brain-Computer Interface Research: A non-invasive example J. Bayliss research group – Rochester Institute of Technology. Will this be us? Goal: “To develop a system that performs real-time EEG signal analysis in order to generate control commands for environmental control, communication, or even simple driving commands” The Hope: “A big signal like the P300 can be recognized via single trial recognition in order to trigger commands on the VR car. We currently have around 85% average recognition accuracy.” Success: “P300” signal response is evoked, trained via biofeedback, used to activate things in a virtual apartment.

5. Electroencephalograph - EEG Brain has continuous electrical activity that can be recorded Pairs of electrodes attached to scalp form distinct channels Weak signal ~millivolts is sent thru amplifier Continuous output recorded via galvanometer.

6. Each pair of electrodes forms a channel to measure something - maybe potential difference between them? Localized anomalies pinpoint physical brain problems Computer waveform analysis: high-speed samples taken 200 times/second to convert analog>digital Commercially available to run on PCs and Macs, you can even use it qualitatively if you’re bad at math Commercially available to run on PCs and Macs, you can even use it qualitatively if you’re bad at math

8. Other Non-Invasive Brain Mapping Techniques Positron emission tomography event-related potentials electro-and magnetoencephalography, magnetic resonance imaging single-photon emission tomography boring
