Suppression of 
Emotional Memories via a Two-Phase Process - Brendan E. Depue,  Tim Curran, 
Marie T. Banich Whether memories can be suppressed has been a  controversial 
issue 
in psychology and cognitive neuroscience for decades. We  found evidence that 
emotional memories are suppressed via two  time-differentiated neural 
mechanisms: (i) an initial suppression by the right  inferior frontal gyrus 
over 
regions supporting sensory components of the memory  representation (visual 
cortex, thalamus), followed by (ii) right medial frontal  gyrus control over 
regions 
supporting multimodal and emotional components of the  memory representation 
(hippocampus, amygdala), both of which are influenced by  fronto-polar 
regions. These results indicate that memory suppression does occur  and, at 
least in 
nonpsychiatric populations, is under the control of prefrontal  
regions.....E-mail: depue{at}colorado.edu

screeds are unwelcomed. Substance—not soap-boxing—please!   These are
sordid matters and 'conspiracy theory'—with its many half-truths, mis-

major and minor effects spread throughout the spectrum of time and thought.
That being said, CTRLgives no endorsement to the validity of posts, and
always suggests to readers; be wary of what you read. CTRL gives no
credence to Holocaust denial and nazi's need not apply.
