The reason why spicy food feels hot even at room temperature. Introduction: A spicy molecule called capsaicin attaches to sensory receptors found on the tongue. Thermoreceptors are the name given to these sensory receptors. There is a change in the distribution of electric charge upon contact with these heat sensors. The result is a depolarization of the cell. This indicates a change in the membrane potential from negative to positive. The sodium ions that enter through the open channels cause the alteration.
