Does a stimulus cause a change?
What is a stimulus? In biology, we can define stimulus as the “detectable change (physical or chemical) in the environment of an organism that results in some functional activity”.
What activates the stimulus?
In one, a neuron works with a sensory receptor, a cell, or cell process that is specialized to engage with and detect a specific stimulus. Stimulation of the sensory receptor activates the associated afferent neuron, which carries information about the stimulus to the central nervous system.
What is an example of a reaction to a stimulus?
As humans, we detect and respond to stimulus in order to survive. For example, if you walk outside on a very sunny day, your pupils will constrict to protect your eye from taking in too much light and being damaged. Your body reacts to the stimulus (the light) to protect you.
How brain processes an external stimulus?
The sensory neurons are located in the different sensory organs such as the eyes, ears, nose, tongue, and skin, and these neurons send signals to the brain regarding the external stimuli. Sensory coding involves sensory receptors that get information from the world, a person’s cells, and parts of the brain.
What are three examples of stimulus and response?

- You are hungry so you eat some food.
