To figure out what epilepsy is all about, it is important to first understand how the normal human brain works. We all know that the brain is the center of the human body, and all human thoughts, feelings, memories, and movements are governed by the brain. In fact, the working principle of the brain is similar to that of a computer, and the brain can be understood as a highly complex electronic network system. In this neuroelectronic network, there are a large number of bioelectrical signals that follow a certain pattern and are transmitted back and forth about 80 times per second. During a seizure in an epileptic patient, the electrical signals in the brain are suddenly disturbed for a short period of time, and the frequency of EEG transmission is accelerated, and may even reach as many as 500 times per second. This is analogous to a surge in the power grid.
