What is olfactory adaptation?

Explanation

**Step-by-Step Solution:**

1. **Definition of Olfactory Adaptation**: Olfactory adaptation, also known as olfactory fatigue, refers to the temporary inability to detect a particular odor after prolonged exposure to that specific odor.

2. **Mechanism of Olfactory Adaptation**: This phenomenon occurs because the olfactory sensory neurons (olfactory cells) become less responsive to the odor molecules over time. When exposed to a specific odor for an extended period, these cells may reduce their sensitivity.

3. **Impact on Sensation**: As a result of olfactory adaptation, an individual may find it challenging to distinguish or perceive the odor that they were initially able to detect. This is a normal physiological response of the olfactory system.
