Stimuli is anything that gives a reverse effect in our body or our body responds to it - positively or negatively.Our nerves are the means of contact in our body. All nerves connect to the primary nerve also known as the spinal cord. Nerve endings are found in every surface corner of our skin and scalp. Any momentary feeling in any of these places are carried by the respective nerve - to the spinal cord - to the brain stem to the brain.
In the brain, there are many sectors , where different forms of stimuli are processed, mainly located in three primary divisions in the brain - cerebrum the back portion, cerebellum the top portion and medulla , the middle or the center.
All of this is done in a nanosecond, which tells you what you are dealing with or what you are feeling.

Sensory receptors are specialized cells that detect stimuli such as light, sound, temperature, or pressure. They convert these stimuli into electrical signals that are then sent to the brain for processing and interpretation. Examples include photoreceptors in the eyes for detecting light and mechanoreceptors in the skin for detecting touch.
The brain processes auditory information sent from the ears, interpreting sounds and enabling us to understand and respond to them. It also helps us focus on specific sounds or filter out background noise. In turn, the brain can influence how we perceive and react to auditory stimuli.
Sound
The time it takes for the brain to react to external stimuli can vary depending on the type of stimulus and individual factors. Generally, the brain can react to simple stimuli, like a visual or auditory cue, in milliseconds. However, more complex stimuli or tasks may require longer processing times.
Brain is likened to a telephone switchboard because brain is connected to series of network that accept messages from various stimuli, after accepting the stimuli, the brain will send reflexes in accordance with the messages sent.
it is our response to a given stimuli. . it is the message sent by our nerves to our brain

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.

When light from an object enters our eyes,it will pass through the pupil and stimulates trhe light sensitive cell on retina.The stimulis are then sent to the brain through opitical nerve.The brain interprets the stimuli and form the sensation of seeing things
Receptors provide information about the intensity of a stimulus through the frequency of action potentials they generate. Higher intensity stimuli result in higher frequency of action potentials being sent to the brain, signaling a stronger stimulus. This frequency coding allows the brain to interpret the intensity of stimuli.
