Acetylcholine and Spatial Memory Study

What was the aim of the study by Rogers & Kesner?

• To assess the relationship between sleep and memory retention.

• To investigate the role of the hippocampus in memory formation.

• To analyze the impact of diet on cognitive function.

• To explore the effects of stress on memory recall.

How many rats were used in the experiment?

• 10 rats

• 20 rats

• Unknown

• 5 rats

What type of maze did the rats acclimate to?

• circular maze

• labyrinth maze

• linear maze

• radial arm maze

What substance was injected into the rats to block acetylcholine?

• Atropine

• Nicotine

• Curare

• Sarin

What was the purpose of using a saline solution in the experiment?

• To enhance the color of the solution.

• To act as a preservative for the samples.

• To provide a controlled environment that mimics physiological conditions.

• To increase the salinity of the solution.

Where were the injections made in the rats?

• In the muscle tissue

• In the lungs

• Intraperitoneal cavity, subcutaneously, or intravenously.

• In the brain

What does scopolamine do to acetylcholine receptor sites?

• Scopolamine blocks acetylcholine receptor sites.

• Scopolamine has no effect on acetylcholine receptor sites.

• Scopolamine stimulates acetylcholine receptor sites.

• Scopolamine enhances acetylcholine receptor activity.

Why was it important that the rats were familiar with the maze before the experiment?

• It allowed the rats to navigate the maze faster due to prior experience.

• It made the maze more challenging for the rats during the experiment.

• It ensured that the results reflected the experimental variables rather than learning effects.

• It ensured the rats were less stressed during the experiment.

What could be a confounding variable in this study?

• Participant age or socioeconomic status could be a confounding variable.

• Participant height

• Participant dietary preferences

• Participant favorite color

What is the significance of acetylcholine in memory formation?

• Acetylcholine has no role in the brain's cognitive functions.

• Acetylcholine is significant in memory formation as it enhances synaptic plasticity and facilitates the encoding of new information.

• Acetylcholine inhibits synaptic plasticity and prevents memory formation.

• Acetylcholine is primarily involved in muscle contraction, not memory.
