the role of semantic and episodic memory in remembering and imagining

Question 1

brain leisons

Answer 1

any part of the brain’s tissue that has been damaged from and injury or a disease.

Question 2

Alzheimers

Answer 2

a neurodegenerative disease that causes the loss of neurons to occur in the hippocampus, therefore resulting in memory loss.

Therefore episodic memory declines and as Alzheimer’s progresses, we can see a decline in semantic memory as well.

The cortex can shrink as well and ventricles can enlarge.

Question 3

what causes Alzheimer’s

Answer 3

• amyloid plaques ( protein deposits )
• Neurofibrillary tangles ( unhealthy deposit in and between neurons )
• cortical shrinkage

Question 4

Alzheimer’s symptoms

Answer 4

• memory loss
• personality change
• repetition
• confusion and disorientation

Question 5

Aphantasia

Answer 5

people are unable to produce visual images in their mind.

they, therefore, have a reduced ability to recall episodic memory

Question 6

what causes Aphantasia

Answer 6

damage to the visual cortex because we don’t actually see things until our brain registers it.

Although people can be born with it
