Answer: That stimulus information is lost as soon as ions flow into the cell.
Explanation:
The brain feel the same "cool" perception whether a neuron is activated by mint or by cool temperatures because the menthol will trick the body of an individual in such a way that the individual feels cold, even when the person isn't. Menthol affect sensory receptors where feelings of pain, touch, and temperature are being monitored.
Under the human skin, there are neurons which detect these sensations, and monitor the environment through specialized proteins. These proteins control the ion channels and once stimulus information is lost as soon as ions flow into the cell, the brain feel the same "cool" perception whether a neuron is activated by mint or by cool temperatures.
