direct control of the nervous system
A change in behavior caused by a stimulus is known as a reflex. It is an automatic response to a specific stimulus that helps organisms quickly react to potential dangers or opportunities in their environment. Reflexes are typically innate and do not require conscious thought.

Local responce is a small change in membrane potential caused by a subthreshold stimulus.
Stimuli are things in the environment that cause change. A reaction to a change in the environment is a reaction to a stimulus.

Dishabituation is the process by which an organism's response to a stimulus increases after a change in the stimulus that had previously been habituated to. It occurs when a previously habituated response is restored following a period of stimulus alteration or the introduction of a new stimulus. This phenomenon highlights the difference between habituation, which is a decrease in response, and the re-engagement of that response when conditions change. Dishabituation demonstrates the adaptability of organisms to their environments.
The change is actually a stimulus and when the organism reacts to the stimulus, it becomes a response. Overall, The answer is a stimulus.
A change that causes a response in your body is a stimulus. When a stimulus is detected by the body, it triggers a reaction that helps maintain balance and homeostasis.
This process is known as regulation. Nervous or hormonal signals trigger a series of cellular responses within the organ, leading to changes in its activity. This allows the body to maintain homeostasis and respond to internal and external stimuli.
The word is "transition."
