Brain Electronics

|Our brain activity is ralated to the consiousness, every body knows about that thing, brain is information processor it gets the raw data and analyse it and all this is related to the consiousness though some exceptions are there such as Somnambolism in which we work and speak and do whatever is in mind during sleep.

    If we talk about the processing of brain we come across many things for example we are enjoying the beauty of NIAGRA FALLS than its simply means that our eyes are sensitive to the images phases and  colors and our brains are so cool that they are processing the whole that data without any bit error and make us to take pleasure from what we are seeing and what we are doing .

We conclude one thing and its that our brain is really a very good processor having very veryh less pr no margin of error. Thats the moment when we came across the idea that why we should not develop the systems similar to the brains in work and do the things for us like we observe underground with a short- wavelength radar system. Anti-personnel plastic landmines are buried shallowly below the surface. We measure amplitude and phase of the reflected wave. Then we obtain a complex amplitude image (top-left, brightness: amplitude, hue: phase) which is decomposed into amplitude (top-center, brightness) and phase (top-left, hue). We, human being cannot tell where a landmine exists. But the super brain radar system can perform the segmentation and visualization of the plastic landmine as shown in the bottom image. The system can learn adaptively soil and stone conditions as well as mine shapes which depend on conflict areas. We can also see through the walls with such radar systems.



   Brain extracts information from the other organs through a digital way called the pulses and after processing it sends commands to the others organs through the pulses. There is an electromechanical system presents in the  human body which works jointly and are in full synchronization with each others. The brain produces varying proportions of brain wave types, depending on its current levels of relaxation, focus, and other mental states. Each type of wave has its own characteristic frequency range, which can be read by electroencephalography. Many people’s brain waves will synchronize to lights and sounds pulsing at brain wave frequencies, and this makes the brain change its state — a process called “entrainment.” By playing sequences of pulses into your eyes and ears, you can program your brain to follow any brain wave experience you like.

      Brain is commmonly working in a five different frequency bands and they are
Delta waves  .5 - 4 Hz
Theta waves  4-8Hz
Alpha waves  8-13Hz
Beta waves  13-30 Hz
Gamma waves  30-100 Hz



Brain generates the delta waves when it is in unconsious mode or in a sleep mode, when it is in a subconsicous mode it is in  the theta mode and also when it turns into active mode it sends alpha waves
and during focussing some things it sends beta waves and when it is in a confusing state it sends the gamma waves.
