Definition & Meaning of "olfactory bulb"

What is "olfactory bulb"?

The olfactory bulb, also known as the olfactory brain, is a small, rounded structure located at the front of the brain. It plays a crucial role in the sense of smell, as it receives and processes olfactory information from the nose. The olfactory bulb contains specialized cells called olfactory receptors that detect odor molecules in the air, allowing us to perceive and distinguish various smells. It is an essential component of the olfactory system and contributes to our overall sensory experience.
