Sensation is a process that allows us to be aware of the physical world we reside in as well as the internal processes in our body. The human brain collects information through the five senses and interprets signals throughout the body. Hearing, vision, smell, touch, taste all these sensory systems help our body to perceive sensation through the receptors at the nerve endings.
Each sensory system is designed uniquely and connected with receptors, which detect specific information in the environment. Once they detect any information in the environment, they instantly convert them into electrochemical neural impulses. The brain then decodes all those messages which give the brain the ability to have understanding about the environment then experience sensation.
Sensation is quite remarkable in many ways. Ability of the receptors to detect faint stimuli and send signals to sensory organs determine the strength and accuracy of sensation without an individual.
