Whether we are mentally active, resting or asleep, the brain
always has some level of electrical activity. The study monitored the frequency
and location of electrical brain waves through the use of EEG (electroencephalography).
EEG headset are placed in standard locations of the head.
The fundamental unit of the brain is termed a neuron - this
is just the scientific term for a single brain cell. A neuron communicates to
other neurons via electrical impulses, also called potentials, and chemical
secretions called neurotransmitters, whose effect is not perfectly understood.
Electrical input to one neuron comes from many others, each having a specific
amount of influence, or weight, on the neuron.
These electrical waves that our brain produces, by the help
of EEG headset turn into images or can even be used to produce music.
This machine is very complex. It is used widely in medicine,
psychological studies and even in arts.
