Â­TheÂ­ three most basic units in electricity are voltage (V), current (I, uppercase i) and resistance (r). Voltage is measured in volts, current is measured in amps and resistance is measured in ohms. A neat analogy to help understand these terms is a system of plumbing pipes. The voltage is equivalent to the water pressure, the current is equivalent to the flow rate, and the resistance is like the pipe size. How Power Grids Works.
Biofeedback is a method that uses the mind to control a body function that the body normally regulates automatically, such as skin temperature, muscle tension, heart rate, or blood pressure. When you are first learning biofeedback, you will have sensors attached to your body and to a monitoring device.
This is because the source of many symptoms is electrical-the brain waves-not chemical. Neurofeedback is a drug-free, non-invasive training process that can help restore the brain waves to better patterns of functioning.he neurofeedback equipment detects the emergence of excessive brain wave activity. (This could be too much all over, as with a seizure. Or it could be too much of some and not enough of another, as in migraine or ADHD.) At that moment, the music will stop or stutter for a fraction of a second.
