BCI: Compare 8 to 16 channel 10-20 electrode coverage

Purpose: The purpose of this document is to demonstrate the differences in monitoring coverage when increasing the number of electrodes of the UltraCortex Mark IV from 8 to 16 then re-configuring the software to receive input from the expansion. The end result being denser coverage with an increase in reading sensitivity from brain wave activity. Again the study is not meant to be of scientific or medical origin but rather to highlight/compare the outcome resulting from an increase of 8 additional channels.

Study Examples:

8 Channel: Test subject at rest sitting in a chair with little to no physical activity other then an occasional eye blink.

16 Channel: Test subject at rest sitting in a chair with little to no physical activity other then an occasional eye blink.

Human Brain Monitoring / Machine Learning Study

Purpose: The purpose of this document is to show the interoperability of the OpenBCI hardware and software in action while monitoring human brain activity.

Please note the examples, below, are not meant to depict a scientific or medical study. This especially applies to the alcohol study, which would normally be considered a contaminated study; however, the results were too interesting not to include. 
They are meant to outline the system in actual use while showing a resulting difference in brain activity detected by the system (e.g. machine learning) during the monitoring session of a test subject under different conditions. In addition, these studies also highlight the recorded playback feature of the software and integration with other third party software. 

Study Examples:

At Rest Study: Test subject at rest sitting in a chair with little to no physical activity other then an occasional eye blink.

The video speed has been increased by 2 for presentation purposes.

Alcohol Study: The same test subject at a different day/time sitting in a chair with little to no physical activity, except the occasional eye blink. Test subject is under the influence of alcohol.

Brain Influence: Test subject at rest sitting in a chair with little to no physical activity other then an occasional eye blink. This study example depicts brainwaves from a test subject being sent to a computer and interfaced with third party software in order to influence the computer to spell pre-determined letters using only mental focus and thought. Using the third party P300 Speller software, 2 letters are defined and the test subject focuses on each letter, while watching the screen, and envisions the letters being spelled by the computer in order to influence the outcome.
