The surgery was innitially a success, the seizures almost completely stopped, however soon after they found out he wasnt able to form new memories.

• memory is not on unitary structure
• evidence to show the STM and LTM were distinct stores, as he was able to hold information for breif periods of time in STM but was unable to move this information into LTM.

• if the hippocamous is damaged or removed this will lead to severe impacts on our memory
