Fish olfactory bulb

WebThe Olfactory Bulb is a bulb of neural tissue within the dog’s brain. It is located in the fore-brain and is responsible for processing scents detected by cells in the nasal cavity. It is approximately 40 times larger in dogs than in humans, relative to total brain size. A humans brain is dominated by a large visual cortex whilst a dog’s ...
