ANT 200 Lecture Notes - Lecture 7: Olfactory Bulb, Chordate, Cerebellum
Document Summary
Neuroendocrine system: complex transducer system: introduction to dynamic. Not important to have all kinds of neurons. Orienting polarized segments toward food, away from danger. Simple worm niche: somewhere between upper levels of sediment. Consider how life history pattern is interrelated w/ complexity and anatomy of behaviors. Worms do not have other sources of perception. Fruit fly: detailed information about each part of these bodies through sensory modalities: complex and similar to what we experience. Also allow other factors to shape formation of networks. Complex adaptive features provide for some nongenetic capacity to respond to variations. How we learn to not bump into walls. Neuron: multiple dendrites with electrical signals just as one axon --> Neuron: multiple dendrites with electrical signals just as one axon --> transmit signals to other cells. Axon: grow 7 feet at service of relaying signals to target tissue. Fruit flies, different patterns of neural projection in embryological development: controlled by critical alleles.
