Aim
To investigate the role of acetylcholine in memory formation
2
Method
A lab experiment with a group of lab rats
3
Procedures
Rats were trained to go through a maze and were given food when they go to then end
Once trained, they were then split into three groups
- group 1: were injected with scopolamine, a drug that blocks acetylcholine from functioning
- group 2: were injected with physostigmine, a drug that speeds up acetylcholine in the body
- group 3: control group, so no injection
rats were places back in the same maze
4
Results
Rats injected with scopolamine were slower and made more errors that both other groups
rats injected with physostigmine ran the maze quicker and with less errors that the control group
5
Conclusion
Acetylcholine plays an important role in creating a memory
neurotransmitters, agonist or antagonist
