Yes, the intensity of the stimulus can be indicated by the frequency of action potentials generated by the neurons in response to that stimulus. A higher intensity stimulus typically leads to a higher frequency of action potentials being fired by the neurons.
Sensation is defined as the process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment.
The nervous system works with the endocrine system to create a response to a stimulus. The nervous system detects the stimulus and sends signals to the endocrine system, which releases hormones that help regulate the body's response to the stimulus. Together, these systems coordinate a response to the stimulus.
The FREQUENCY of action potentials that are conducted into the central nervous system serves as the code for the strength of the stimulus. This frequency code is needed because the amplitude of action potentials is constatnt (all or none). Acting through changes in action potential frequency, tonic receptors thus provide information about the relative intensity of a stimulus.
A stimulus is a signal that triggers a response in the body. When a stimulus is detected by sensory receptors, it sends signals to the nervous system. The nervous system then processes this information and coordinates a response, which can involve actions such as movement, secretion of hormones, or changes in heart rate.
Stimulus adaptation can be influenced by the intensity of the stimulus and the duration of exposure. A strong or intense stimulus may lead to quicker adaptation as the sensory receptors become less responsive over time. Additionally, prolonged exposure to a constant stimulus can cause sensory fatigue, where the nervous system becomes less reactive, resulting in diminished perception of that stimulus. Both factors contribute to the brain's ability to prioritize new or changing stimuli over constant ones.
Fundamentally the system involved in a reaction to a stimuli is the nervous system.

The process of receiving and representing stimulus energies by the nervous system is called sensory transduction. This is where sensory receptors convert physical or chemical stimulus energy into electrical signals that can be transmitted and processed by the brain.
The stimulus that triggers responses in the nervous system is typically a sensory input, such as touch, sound, light, or chemicals, that is detected by sensory receptors in the body. This information is then transmitted to the brain and spinal cord, where it is processed and elicits a response from the 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)
