Why does adaptation to a strong initial taste diminish perceived intensity?

💡 Explanation

Taste adaptation occurs because continuous stimulation of taste receptors leads to receptor desensitization. This reduces the firing rate of the sensory neurons, therefore the perceived intensity diminishes over time, rather than due to odor depletion or memory effects.
