AP PSYCHOLOGY

Detailed explanation-1: -There are two olfactory bulbs on the bottom side of the brain, one above each nasal cavity. The olfactory bulbs receive information about smells from the nose and send it to the brain by way of the olfactory tracts.

Detailed explanation-2: -The olfactory bulb (Latin: bulbus olfactorius) is a neural structure of the vertebrate forebrain involved in olfaction, the sense of smell. It sends olfactory information to be further processed in the amygdala, the orbitofrontal cortex (OFC) and the hippocampus where it plays a role in emotion, memory and learning.

Detailed explanation-3: -The cerebellum-also called the “little brain” because it looks like a small version of the cerebrum-is responsible for balance, movement, and coordination.

Detailed explanation-4: -In this case, the olfactory nerve is responsible for our sense of smell. The odor information originates in the epithelium of the nasal cavity and is transported to the brain via components of the olfactory nerve (cranial nerve 1-CNI) and the olfactory pathway.
