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.

Examples

1. Her idea starts with the olfactory bulb, a relay station just above the nose that sends smell information deeper into the brain.

2. When an odor molecule binds to a scent receptor, it sends an electrical signal from the sensory neurons to our brain's olfactory bulbs.

3. What does olfactory bulb and smell have to do with it?

4. In carnivores, like wolves and coyotes and foxes if you look at the size of their home range, the olfactory bulb scales with the size of their home range.
