Information on the world around us is obtained from the many channels that our senses provide. Sight, hearing, smell, touch, taste … It is the combination of all these information channels and provides us with the most complete picture of the world.
People receive information about the surrounding space with the help of six senses: the ears, eyes, skin, tongue, nose and vestibular apparatus. The data received by each of them enters the nervous system.
More than half of the inhabitants of the Earth have diseases associated with the organs of vision.

Ears are not only the organ of hearing, but also an important element of the vestibular system – simply, they help the person maintain balance.

The human brain needs time to process signals from the senses, therefore everything that people feel at a certain moment actually refers to the previous moment of their life. Delay of perception is about 100 milliseconds, but the brain somehow manages to compensate for it – the essence of this mechanism to scientists is not yet clear.
Signals from different senses enter the brain at different speeds, so that later the brain creates a single picture from them.
Scary events are sometimes perceived by people as a film with slow-motion shooting, although in reality frightening phenomena are simply more accurately recorded by the brain.
People who are blind from birth and only become conscious at a conscious age can perceive many things with distortion – since their brains do not know how to dispose of unusual information for him, former blind people see people moving away from them as diminishing in size figures.
If any time passes in glasses, turning the space upside down, the brain adapts to this image. When a person takes off his glasses, the world will appear to him upside down for a while.
