چکیده
“And as soon as I had recognized the taste of the piece of madeleine soaked in her decoction of lime-blossom which my aunt used to give me ... immediately the old grey house upon the street, where her room was, rose up like a stage set to attach itself to the little pavilion opening on to the garden which had been built out behind it for my parents ...; and with the house the town, from morning to night and in all weathers, the Square where I used to be sent before lunch, the streets along which I used to run errands, the country roads we took when it was fine ...”

Adaptive Top-Down Suppression of Hippocampal Activity and the Purging of Intrusive Memories from Consciousness
When reminded of unwanted memories, people often attempt to suppress these experiences from awareness. Prior work indicates that control processes mediated by the dorsolateral prefrontal cortex (DLPFC) modulate hippocampal activity during such retrieval suppression. It remains unknown whether this modulation plays a role in purging an intrusive memory from consciousness. Here, we combined fMRI ...
متن کاملModeling storage and retrieval of memories in the brain
We have proposed a neural network model that stores the incoming information after orthogonalizing it in the same manner as vectors are orthogonalized. The scheme enables the brain to compare a new informational system with those in the memory and store its similarities and differences with the old memories in an economical manner. This allows the brain to have an enormous capacity and yet the ...

متن کاملEgo depletion results in an increase in spontaneous false memories.
The primary aim of the current study was to examine whether depleted cognitive resources might have ramifications for the formation of neutral and negative spontaneous false memories. To examine this, participants received neutral and negative Deese/Roediger-McDermott false memory wordlists. Also, for half of the participants, cognitive resources were depleted by use of an ego depletion manipul...
متن کاملSuppressing unwanted memories reduces their unconscious influence via targeted cortical inhibition.
Suppressing retrieval of unwanted memories reduces their later conscious recall. It is widely believed, however, that suppressed memories can continue to exert strong unconscious effects that may compromise mental health. Here we show that excluding memories from awareness not only modulates medial temporal lobe regions involved in explicit retention, but also neocortical areas underlying uncon...
