The records of extracellular nerve from micro electrode 

Extracellular recording, either electrode or nerve detector records the activity of single or multiple cells in the human body. With multi-channel miniature neural probe, the potential single or wavy nerve that is in the neural net area can be recorded at the same time. By analyzing these images, we can conclude the active relationships among the cells. Therefore, multichannel tiny nerve probe proves that brains can create consciousness on surrounding environment through auditory sense.
