sensation
the subjective awareness of a stimulus; the process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment
Sensation is the process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment. It involves the conversion of physical energy (such as light or sound waves) into neural signals that can be interpreted by the brain. The five main senses involved in sensation are sight, hearing, taste, smell, and touch.
Sensory information from the environment is detected by specialized cells called sensory receptors. These are located within specific organs, such as the eyes, ears, tongue, nose, and skin, and they respond to different types of stimuli. For example, receptor cells in the eyes detect light waves while those in the ears detect sound waves.
Once a sensory receptor is activated, it sends a neural signal to the brain through a series of neurons and synapses. The brain then interprets these signals and creates a perception of the stimulus. For instance, if you see a red apple, your eyes detect the light waves reflecting off the fruit, and the receptors in your eyes send these signals to the brain. The brain then processes the signals and creates a perception of the apple as red.
Overall, sensation is a crucial process that allows us to interact with our environment and helps us to make sense of the world around us.
