The stimulus sends messages to the brain through a process called sensory transduction. When a stimulus is detected by sensory receptors in the body, such as in the eyes, ears, skin, or other sensory organs, it triggers a series of events that ultimately result in the generation of electrical signals. These signals are then transmitted along nerve fibers to the brain, where they are processed and interpreted.
In the case of vision, for example, light entering the eye is detected by photoreceptor cells in the retina. These cells convert the light into electrical signals, which are then transmitted along the optic nerve to the visual cortex in the brain. The brain then processes these signals to create a visual perception of the stimulus.
Similarly, in the case of touch, sensory receptors in the skin detect pressure, temperature, and other tactile sensations. These receptors convert these sensations into electrical signals, which are then transmitted along nerve fibers to the somatosensory cortex in the brain. The brain then processes these signals to create a perception of touch.
Overall, the process of sending messages from sensory receptors to the brain involves the conversion of stimuli into electrical signals, transmission of these signals along nerve fibers, and processing of the signals in the brain to create a perception of the stimulus.
