It explains the role of neurons and synapses in memory formation and discusses factors like age, stress, and depression that contribute to memory loss. The importance of social interaction and mental engagement in preserving memory is highlighted, along with practical tips for maintaining cognitive health.

What is the process called when the efficiency of communication between neurons increases due to repeated interaction?

• Long-term potentiation

• Neuroplasticity

• Neural adaptation

• Synaptic pruning

Which part of the brain is primarily involved in transferring information from short-term to long-term memory?

• Amygdala

• Cerebellum

• Thalamus

• Hippocampus

What neurotransmitter is associated with learning and memory, and its production decreases with age?

• Acetylcholine

• GABA

• Dopamine

• Serotonin

How does chronic stress affect memory?

• It has no effect on memory

• It improves the formation of new brain cells

• It leads to the loss of brain cells

• It enhances memory retention
