The brain can process all the messages that nerve cells in the nose and eyes are sending as they used different cells. The messages get sent directly to the brain. The brain may start telling the mouth to salivate.

Detailed explanation-1: -Each sense receptor responds to different inputs (electromagnetic, mechanical, chemical), transmitting them as signals that travel along nerve cells to the brain. The signals are then processed in the brain, resulting in immediate behaviors or memories.
Detailed explanation-2: -Sensory signals first enter the brain through the thalamus (except for olfaction, which bypasses this area). From there, it is routed to a sense-specific area of the cortex. Cortical areas, in turn, send signals to the brain’s “association areas, ‘’ which combine information from multiple senses.
Detailed explanation-3: -Thalamus: The thalamus is the relay center of the brain. It receives afferent impulses from sensory receptors located throughout the body and processes the information for distribution to the appropriate cortical area. It is also responsible for regulating consciousness and sleep.
Detailed explanation-4: -The spinal cord conducts sensory information (information from the body) from the peripheral nervous system to the brain. After processing its many sensory inputs, the brain initiates motor outputs (coordinated mechanical responses) that are appropriate to the sensory input it receives.
