What did Patient H.M.'s case, plus data from experiments with monkeys, prove about brain regions needed to make new declarative memories?
A) We need at least one intact medial temporal lobe (including hippocampus) in order to make new declarative memories.
B) We need both intact medial temporal lobes (but not hippocampus) in order to make new declarative memories.
C) We need both intact medial temporal lobes (including amygdala) in order to make new declarative memories.
D) The medial temporal lobe and hippocampus are not involved in making new declarative memories.

Patient H.M.'s case and experiments with monkeys showed that the medial temporal lobe, including the hippocampus, is necessary for the formation of new declarative memories. Specifically, removal of the hippocampus in Patient H.M.'s case resulted in severe anterograde amnesia, meaning he was unable to form new memories after the procedure. Additionally, experiments with monkeys showed that lesions to the medial temporal lobe, including the hippocampus, disrupted their ability to form new declarative memories. Therefore, we need at least one intact medial temporal lobe (including hippocampus) in order to make new declarative memories.
