What are the different parts of the stimuli?

Stimuli can be categorized into various parts based on sensory modalities: visual stimuli (light and color), auditory stimuli (sound waves), tactile stimuli (texture and pressure), olfactory stimuli (smells), and gustatory stimuli (taste). Additionally, stimuli can be classified as internal (originating from within the body) or external (coming from the environment). Each type of stimulus can evoke specific responses or perceptions, influencing behavior and cognition.
