Solution:
The solution is:
Short-term memory, or primary memory, is the ability to actively hold a small amount of information in the mind so that this information is immediately available for a short period of time. The duration of this type of memory is seconds and its capacity is to memorize 7 ± 2 elements.
On the other hand, it is noteworthy that the prefrontal cortex handles spatial representation and participates in short-term memory.
The causes of short-term memory loss are pathologies such as:
Aneurysm.
Stroke.
Encephalitis.
Hypoxia.
Epilepsy.
Initial states of neurodegenerative diseases (for example, Alzheimer's).
Damage to the diencephalon.
Korsakoff's syndrome.
