Develop proceeds in an orderly, hierarchical and sequential manner. Define and explain. Describe the process that forms the notochord and the nervous system. Describe decision making in these same terms. Describe behavior in these same terms.
Sensory mechanisms reside at the interface between organism and environment.
What is the difference between the nose as a smell organ and the olfactory neuron as an odor detector. Compare the anatomy and biochemistry of a visual neuron with an olfactory neuron. Sensory organs translate the relevant features of the environment into topographic spatial neuronal maps in the brain. Begin in the spinal cord with a motor neuron. Behavior could mean the coordinated movement of a muscle in an environmental context.
