Week 2: Brain-Behavior Relationships

The brain is a wonderful organ; it starts working the moment you get up in the morning and does not stop until you get into the office. 
Robert Frost

This is an amusing quote; however, it is scientifically incorrect. Yes, your brain is a wonderful organ, but it never really stops working. We are able to interact with our world through our nervous system, which is comprised of our brain and all the nerve cells in the rest of the body. The nervous system and our endocrine system, involved in secreting hormones through our bloodstream, both communicate messages that influence behavior and many aspects of our biological functioning.

This week you learn how the central nervous system, peripheral nervous system, and endocrine system interact to communicate within the body. You will also learn about how our bodies sense things from the environment and transform and organize that sensation into meaningful perceptions of sight, sound, smell, taste, and touch.

Learning Objectives

Students will:
  • Demonstrate comprehension of the relationships among brain structure, neural transmission, and thoughts, feelings, and behaviors
  • Identify major structures and functions of parts of the nervous system
  • Demonstrate understanding about connections between nervous system structures
  • Identify instances of sensory adaptation
  • Identify aspects of basic sensation and perception in regard to vision, hearing, smell, and taste
  • Assess concepts related to perceptual organization
  • Summarize salient characteristics of an individual for case study project
