When the brain receives a signal from the nerves in the skin that touching a hot stove is causing tissue damage, it triggers a reflex to quickly withdraw the hand. This rapid response is involuntary and helps prevent further injury by minimizing the amount of time the skin is in contact with the hot surface.
The stimulus that causes you to pull your finger away after touching a sharp pin is the sensation of pain associated with the pin pricking your skin. This pain signal is sent from your nerves to your brain, triggering a reflex action to move your finger away to avoid injury.
When movement is fast in response to a stimulus, the body sends rapid signals through the nervous system. Sensory neurons detect the stimulus and quickly convey this information to the brain. The brain then processes the information and sends out signals to motor neurons, instructing the body to react accordingly.
It typically takes about 0.25 to 0.5 seconds for a person to perceive a stimulus and react to it. This includes the time it takes for sensory information to travel to the brain, for the brain to process the information, and for the response to travel back to the muscles. Variations in reaction time can occur depending on the individual and the complexity of the stimulus.
The intensity of a sensation is determined by the magnitude of the stimulus that evokes it. This can be influenced by factors such as the strength or amount of the stimulus, the sensory receptors involved, and the sensory pathways that transmit the signal to the brain.
The process of receiving stimulus energy is called sensory reception. It involves the detection of sensory stimuli by sensory receptors in the body, which then transmit signals to the brain for processing and interpretation.
the stimulus is the hot pan causing a signal to be sent to the brain which causes the hand to be pulled away which is the response
There are a number of different ways that the brain perceives stimuli. If a person is hurt, the brain sends a reaction to the body. If something good happens, the brain sends good reactions to the body.

Nervous system
our senses will detect stimulus and send impulse into the integrating centre(brain) to interpret. the brain will produce appropriate response toward the stimulus to the effector. e.g when Telephone ring, the ears will detect the stimulus(sound) and the brain will produce the response to pick up the phone (copy from Yahoo answers)
this answer is just so simple that needs further research music (soft, classical) stimulates your brain, it organizes your brain function. your brain tries to understand or integrates the stimulus (music). brain reacts to external stimuli. your hypothalamus controls temperature, medulla oblongata & pons for pulse, etc.
A stimulus triggers a signal in sensory receptors, which is then transmitted through the nervous system to the brain. The brain processes this signal and initiates a response by sending signals to the appropriate muscles or glands to react to the stimulus.
When taste and smell receptors are activated by a stimulus, they send signals to the brain which are interpreted as specific tastes and smells. This process helps us identify and enjoy different flavors and scents in our environment.
The brain determines the location of a stimulus through a process called sensory perception. This involves the integration of information from sensory receptors in the body, such as the eyes, ears, and skin, which send signals to the brain. The brain then processes and interprets these signals to create a spatial representation of where the stimulus is located in relation to the body.
Brain stimulus receptors are considered "selective transducers" by physiologists. The reason that they are referred to as this is that the receptors convert certain information by turning it to energy.
You CNS reacts in different ways to environment. For example if you are cold your brain will trigger a stimulus and give you goosebumps. Or round the other way, if you are hot then you will begin to sweat.
When a receptor adapts to a stimulus, it sends progressively reduced signals to the brain. The brain interprets this decrease in signals as adaptation, resulting in reduced sensitivity to that specific stimulus over time.
