The brain is an electrical system as it is a network of neurons. Neurons communicate with each other via electrical signal. The more electrical signals corresponds to more brain activity.
The electrodes of an EEG record the electrical changes occurring in thousands of neurons.
The signal received by the electrodes is amplified by an amplifier. Various maps of brain activity is generated by a computer.

- Their main food sources are different.
During the stone age, animals meat and wild fruits were humans' main food source. As we entered the agricultural age, we started to developed food sources that were easy to produced and provide us with high calories. This is when we slowly transitioned into mostly consuming crops such as Potatoes, rice, and corn.
