An increase in posterior alpha activity predicts successful long-term memory encoding. This suggests that functional inhibition of occipital cortex is a requirement for successful memory formation. (A) Subjects were instructed to rehearse visually presented word triplets during a 3.4-s period. Later memory for the triplets was tested. This allowed for characterizing the brain activity during the rehearsal interval predicting successful memory formation. (B) The alpha activity was stronger for Later Remembered compared to Later Forgotten triplets. (C) The sources of the alpha activity predicting memory encoding were localized in the occipital cortex.
