Transcript of Acetylcholine and Memory

Discovered by Henry Hallett Dale in 1914 and its existence was later confirmed by Otto Loewi
A chemical that is found between the nerve synapses, or gaps, between nerve cells
Plays a significant role in the signal of muscle movement, sensation of pain, learning and memory formation, and the regulation of the endocrine system
Acetylcholine
Acetylcholine and Memory
Martinez and Kesner on the role of neurotransmitters in learning and memory (1991)
Relationship between Acetylcholine and Memory
Acetylcholine allows us to connect different parts of memory, such as a name with a face
Acetylcholine deficiency can lead to memory loss, memory lapses, and loss of visual memory
Aim
:
Determine the role of acetylcholine on memory.
Group 1, injected with scopolamine, was slower at finding their way around the maze and made more errors than the other 2 groups. Group 2, injected with physostigmine, ran through the maze and found the food quicker and took fewer wrong turns than the other 2 groups.
Strength
:
The use of an experimental method with a control group made it possible to establish a cause-and-effect relationship between levels of acetylcholine and memory.
Limitation
:
It is questionable to what extent the findings can be generalized to humans.
Results
Research Method:
Laboratory Experiment
