my brains - let me show you them by Liz Henry on flickr

Here is a useful presentation we will use in class.

  1. Label a diagram of the brain.  Annotate the diagram to include functions of the parts.
  2. Explain how animal experiments, lesions and FMRI scanning can be used to identify the brain part involved in specific functions.
  3. Explain sympathetic and parasympathetic control of heart rate, movement of the iris and blood flow to the gut.
  4. Explain the pupil reflex and discuss the concept of brain death and the use of the pupil reflex in testing for this.
  5. Outline how pain is perceived and how endorphins can act as painkillers.

This next section, E5, is all about the human brain, brain function, fMRI, sympathetic and parasympathetic nervous systems, pupil reflex, brain death, and the perception of pain.  Phew!  That’s a lot of concepts. 

We’ll again use click4biology as a good resource, and this presentation from Mr Taylor in Bandung to help us get through it all.  Here are the key questions we need to answer:

  • What are the major parts of the human brain, and what are their functions?
  • How do animal experiments, lesions and fMRI scanning used in identifying which part of the brain is involved with specific functions?
  • How are heart rate, movements of the iris, and blood flow to the gut controlled by the sympathetic and parasympathetic nervous systems?
  • What is the pupil reflex and how is it used to determine brain death?
  • How is pain perceived and how to endorphins help to alleviate it?
