Does this scene look familiar to you? C’mon, admit it!
The cingulate gyrus is located above the corpus callosum, and it is the thing responsible for keeping your temper in check. As you would have probably either witnessed or experienced yourself, not everyone has a good control over their sense of aggressive tendencies. It also is activated when you experience a painful sensation: it regulates which emotions you choose to express.
As the name suggests, the olfactory complex is involved in your sense of smell. More specifically, it helps to both identify the type of smell by picking up scent messages from the olfactory bulb and make you consciously aware of your sense of smell. This is one of the areas, unfortunately, that humans have had to sacrifice in exchange for our acute sense of sight and our language and cognitive skills; compared to our pets, our olfactory capacity is fairly limited: in other words, there has to be millions of molecules in the air for us to detect a certain smell whereas only one our dog or cat will need probably need a few.
The olfactory complex is located within the medial or central temporal lobes.
