Sensory stimuli are the various forms of physical energy that our sensory organs detect from the environment, such as light waves, sound waves, or pressure on the skin.
The process by which our sensory receptors and nervous system receive and represent sensory stimuli.
The conversion of sensory stimuli into neural signals that can be interpreted by the brain.
Thresholds: The minimum amount of stimulus required for detection or for a particular sensation to occur.
