心影头环 SOULINK ZERO
Your brain is more powerful than you can imagine
In a human, the brain has billions of neurons - each of which is connected by synapses to other neurons. They communicate with each other by action potentials or nerve impulses generated by a potential difference across the cell membrane. Although the electrical activity can be detected by technology, the average (~0.07 volts) is actually quite small when compared to a those in a computer (~12 volts).

What is happening in your brain
How neurons talk to each other
In a human, the brain has billions of neurons - each of which is connected by synapses to other neurons. They communicate with each other by action potentials or nerve impulses generated by a potential difference across the cell membrane. Although the electrical activity can be detected by technology, the average (~0.07 volts) is actually quite small when compared to a those in a computer (~12 volts).
You could imagine that each electrical transmission is like a star. When several transmissions are going through the neurons, the inside of your brain would look like billions of stars twinkling in the sky.
Figuring out the content of the communication or the electrical activities becomes important, as we try to apply our findings to different fields such as medicine, education, entertainment, etc. to further understand how the brain works.
How portable EEG devices read your brain
Portable EEG devices record your brain activity in the same way as an EEG used in hospital settings, just with fewer electrodes and recoding from fewer areas of the brain. Neurons communicate via electrical impulses that can be picked up through the scalp by EEG. Thus, SOULINK zero, a portable EEG equipment, detects the electrical activity from part of the prefrontal cortex that is thought to be related to higher cognitive functions such as making a decision, thinking, executive functions, etc.
