Case 1 tells the story of Henry Molaison (HM), a man with no memory. He lost his memory due to the operation of suctioned out the hippocampus to treat his epileptic seizures. At that time, it was not known yet that the hippocampus was essential for making memories. After operation, his seizures were significantly reduced, but Henry suffered a global amnesia. Owen et al. (2007) describes patients with global amnesia as perceptive and attentive but with a total loss of short-term memory and some trouble accessing memories of the recent past. Henry could not learn new things as he quickly forgot everything that he had learned. He could learn at a subconscious level only. Henry Molaison (HM), known to the world as ‘Patient HM’ has been called…show more content…
Memory is the process involved in retaining, retrieving and using information about stimuli, images, events, ideas and skills after the original information is no longer present. We can relate this case with what we learn in psychology. Short term memory holds information from 15 until 30 seconds whereas long term memory holds information for years. Short-term memory (STM) is the system that is involved in storing small amount of information for a brief period of time while long-term memory (LTM) is the system that is responsible for storing information for long periods of time and recall information about past events in lives and knowledge learned. Without the hippocampus, the information from the short-term memory (STM) cannot be stored in long term memory (LTM). The hippocampus is a very important part of the human brain to store our memories. If we lost it, we will lose all our conscious memories. From Henry’s case, it also discovered that there are multiple memory storage areas located at different parts of the brain while the hippocampus is important to consolidate short-term memory to long-term memory. The removal of hippocampus caused Henry to suffer until he died as he lost the ability to make new conscious
