SENSORS: WHAT ARE THEY AND HOW DO THEY WORK?

1. What are sensors?

Sensors are clips that pick up the sensitive electrical signals from the neurons of the brain. They are attached to the ears and scalp in order to perform their function. The signals that they detect are millionths of a volt (microvolts) and must be amplified in order to be interpreted by the computer software.

2. How do I use the sensors?

There are three sensors used during a training session and can be placed in either of these orders: (1) two ear clips and one flat sensor or (2) two flat sensors and one ear clip. Either combination completes the circuit. Before placing the sensors to the scalp or earlobes it is recommended that the areas be scrubbed with a light abrasive (ie: Nu-Prep). This will help secure a better connection for the sensors. All sensors should be covered with a conductivity paste or wax. This will further enhance the sensors ability to capture electrical signals. Finally, attach your sensors to the amplifier. It is recommended that you use the highest quality amplifier possible. The amplifier takes the signals from the sensorsand amplifies the signal so the software can interpret it accurately and efficiently. If the amplifier is not able to increase the signal data sufficiently, then the software will not display adequate information to conduct training. Once all items are connected and attached, you can move on with the training.

3. How do I place the sensors?

Measurement is essential in receiving accurate, clear information so keep that in mind through the entire process. Once the C4 sensor is placed, take a measurement to verify that it is in the correct site. A sensor placed higher or lower than the C4 will not be able to accurately collect information. Make sure the site is prepped and that each sensorhas conductivity paste or wax. Before placing the sensor, move all hair so the sensor is directly placed on the skin without interference.
