AP PSYCHOLOGY

Detailed explanation-1: -If one or both parts of the hippocampus are damaged by illnesses such as Alzheimer’s disease, or if they are hurt in an accident, the person can experience a loss of memory and a loss of the ability to make new, long-term memories.

Detailed explanation-2: -If the hippocampus is damaged by disease or injury, it can influence a person’s memories as well as their ability to form new memories. Hippocampus damage can particularly affect spatial memory, or the ability to remember directions, locations, and orientations.

Detailed explanation-3: -Damage to the hippocampus can cause a condition called amnesia that prevents people from forming new memories and remembering past experiences.

Detailed explanation-4: -In addition, hippocampal neuronal networks encode events and places that are common across related episodes. This combination of coding properties suggests that the hippocampus contributes to declarative memory by mediating the construction of a “memory space” composed of a network of linked episodic representations.

Detailed explanation-5: -This has been shown in numerous patient lesion studies, where damage to the medial temporal lobe, which includes the hippocampus, typically produces a dramatic impairment in long-term memory and little or no impairment in implicit memory.
