What did the case of Henry Molaison HM teach us about the function of the hippocampus? Henry Molaison (HM) taught us about memory by losing his. HM, age 60. Up until then, it had not been known that the hippocampus was essential for making memories, and that if we lose both of them we will suffer a global amnesia.
What did we learn from Henry molaison? Another key discovery from Henry was the finding that he had retained the ability to form non-declarative memories, which took the form of improvement in motor skills. Along with his simple recognition memory, motor memory helped smooth challenges Henry faced as he aged, such as learning to use a walker.
What did Clive Wearing teach us about the function of the hippocampus? Answer: Clive Wearing taught us about hippocampal dependent formation of long term memory. Because the hippocampus is important for the creation of long term memories, his injury resulted in an inability to form new explicit memories following the injury, also called anterograde amnesia.
What did researchers learn about the role of the hippocampus and memory from HM quizlet? Cognitive psychologists have categorized memories into different types. HM’s study suggests that the hippocampus is essential for explicit (conscious) and declarative memory, but not implicit (unconscious) procedural memory.

Aim/Method: To study the role of the hippocampus in memory. Results: HM could not recall ever doing those tasks and claimed he did not know how to do them but after training, he could perform them perfectly.
What did Patient HM teach us about memory what type of memory did he lose what part of his brain was damaged?
Molaison’s general condition has been described as heavy anterograde amnesia, as well as temporally graded retrograde amnesia. Since Molaison did not show any memory impairment before the surgery, the removal of the medial temporal lobes can be held responsible for his memory disorder.
What has the study of HM revealed about the role of the hippocampus in memory?
generated five main findings: that memory is a distinct psychological function, that amnesia spares short-term and working memory, that amnesia is an impairment of declarative and episodic memory, that the hippocampus is a core brain structure supporting memory, and that the hippocampus supports the permanent

What does the hippocampus do?
Hippocampus is a complex brain structure embedded deep into temporal lobe. It has a major role in learning and memory. It is a plastic and vulnerable structure that gets damaged by a variety of stimuli. Studies have shown that it also gets affected in a variety of neurological and psychiatric disorders.
What caused the damage to Clive’s hippocampus and other areas of the brain that control emotion and behavior?
Clive Wearing was a musician who got a viral infection – encephalitis. This left him with serious brain damage in the hippocampus (biological cause), which caused memory impairment (effect on cognition). He suffered from anterograde and retrograde amnesia.
