ANT 200 Lecture Notes - Lecture 12: Olfactory Bulb, Distant Relatives, Diencephalon
Document Summary
Part 2: different parts of brain comparing birds and mammals. Olfactory bulb takes up large volume of the brain. More efficient to do it this way: saves time. Especially for food that is toxic: help you choose the right food and right time to eat. Tell when strawberries are overripe v. when they are not. Doesn"t help when discriminating against healthy and unhealthy animals. Cells: nerve projections to brain for memory formation/recollection. Humans have many broken pseudogenes that function in chimpanzees. Why do we have 1/10? dozens of genes w/ sequence. Really important to think about that it doesn"t cost that much to be able to do this. Smell may cause a conflict between auditory and visual information. Help in social interactions to form memories: important, some of basal parts of cerebrum. Sour milk might actually be good (capacity to diminish nuances) Auditory/visual input in social niche: persist for long enough to get information.
