Question 2

Rogers and Kesner case study

Answer 2

Rogers and Kesner conducted an experiment to determine the role of acetylcholine in the memory formation. There was a group of rats and they were split into 2 groups, The first group was injected with scopolamine which blocks the acetylcholine receptor and the second group was the control, given a placebo injection. This was done to make sure that the fact of getting an injection alone was not responsible for change of memory. After being injected the rats were then placed into a maze to see how long it would take them to get out. The findings were that the scopolamine group took longer and made more mistakes to get out of the maze whereas the control group learned faster and made fewer mistakes. They concluded that acetylcholine plays a huge role in memory formation.
