Sensation is the process by which our bodies detect and respond to stimuli from the environment. This involves our sensory organs, such as the eyes, ears, skin, nose, and tongue, which receive information about light, sound, touch, taste, and smell. The sensory receptors convert these stimuli into electrical signals that are sent to the brain for interpretation. Once the brain receives these signals, it processes the information, allowing us to perceive and understand our surroundings. This perception helps us react to different situations, such as moving away from danger or enjoying a delicious meal. Sensation is essential for our daily experiences and interactions with the world.
