WORLD FIRST 576 MEGA PIXEL CAMERA WITH 2.5 Petabytes


 
      WORLD FIRST 576 MEGA PIXEL CAMERA WITH 2.5 Petabytes  is HUMAN EYE




HOW THE EYE WORKS:

Light waves from an object are reflected on the pupil through the cornea. The pupil constricts to accommodate the required light response for optimum vision. The bent light waves are reflected on the crystalline lens and nodal point, located behind the eye lens surface. Here, the image is reversed and inverted, before passing in 'clear focus' on to the retina. The retina registers tiny photons of light and turns light impulses into electrical signals. These signals are sent via the optic nerve, to the occipital cortex. Here the electrical signals are interpreted as a visual image.


HOW THE BRAIN WORKS




How does the brain receive the information ? The information is series of electrical impulses that our sensory organs have received, passed to the brain from one neuron to another. The information goes through the nerves in the body and then the brain registers, and sorts the information. The information or memories are either stored for future use, long term use or immediate use.
