Sensation

“A sensation is a subjective knowledge produced from the stimulation of a sensory receptor (a specialized nerve cell that is excited by some physical or chemical stimulus). Sensations are presumed to arise as a result of nerve activity in certain areas of the cerebral cortex, which receive incoming signals from the sensory receptors.”

Sensation is the stimulation of sensory receptors which absorb the energy from the physical environment and convert it into the neutral impulses and send it to the brain.

Perception

Perception can be defined as our recognition and interpretation of sensory information. Perception also includes how we respond to the information. We can think of perception as a process where we take in sensory information from our environment and use that information in order to interact with our environment. Perception allows us to take the sensory information in and make it into something meaningful.”
