Unformatted text preview: tivates the left prefrontal cortex.! In the event-related analysis, they contrasted trials that
were subsequently remembered to those that were
subsequently forgotten. Activations in the prefrontal cortex
were attributed to cognitive control mechanisms (and not
encoding processes per se) that process information at
various levels. These prefrontal regions then interact with
medial temporal lobe mechanisms that actually encode or
consolidate the information into a lasting memory trace.! Content vs. Control: The Reactivation of Cortical Areas!
How are stored memories represented in the brain?!
They are probably widely distributed, and may involve the reactivation of cortical processes that
were engaged during the initial processing of the remembered event.! Proceedings of the National Academy of Sciences, 2000! Encoding of visual

words! During a study phase, subjects view words paired with
sounds and words unpaired with sounds.!
During a recognition test while being scanned, subjects
respond “old” or “new” to visual words.!
Words that were previously paired with a sound reactivate the auditor...
