Imaging Techniques Discussion Forum 2.1

Before the advent of modern imaging techniques, scientists and clinicians relied on autopsies of people who suffered brain injury with resultant change in behavior to determine how different areas of the brain were affected. What are some of the limitations association with this kind of approach? How does it differ in terms of modern approaches?

The Brain As a ‘Computer’ Discussion Forum 2.2

There is an idea that the brain functions similar to a computer. Based on what you’ve read so far, which brain functions do you think would computers be the best at imitating? What about the worst at imitating?

Reaction Rate Discussion Forum

What is the difference between reaction rate, rate law, and reaction order?

1. You need to respond to my questions and to at least four classmates substantially over three days in a manner that furthers the discussion. Some ideas for responses might be:

2. Go a step further and describe the ways in which reaction rate can be expressed, including units and or equations.

What is collision theory?

1. You need to respond to my questions and to at least four classmates substantially over three days in a manner that furthers the discussion. Some ideas for responses might be:

2. Go a step further by explaining in terms of collision theory, explain how temperature, concentration, activation energy, and molecular orientation affect the reaction rate of a chemical equation.

3. Give specific examples of chemical reactions and state the changes that occur when one of the above properties changes.
