How are oders received and tranfered to the brain?

Odors are detected by olfactory receptors in the nasal cavity when odor molecules bind to them. This stimulation generates electrical signals that are transmitted via the olfactory bulb to various brain regions, including the olfactory cortex. From there, the signals are processed and integrated with other sensory information, allowing us to perceive and identify different smells. This process plays a crucial role in memory, emotion, and behavior.
