Flashcards in Week 11 Deck (15):
Describe the network of memory traces
The formation of networks within the memory to encode information and memories. I.e. linked subjects, chair, sitting, legs, sofa
Memory traces are associated _____ info, or ____ info
As learning increases, the _____ diminishes, and your _____ decreases
rate of improvement, reaction time
Describe Hebbian Theory
Neurons that are activated simultaneously, wire together. After repeated stimulation, synaptic transmission is quicker. "Wire together, fire together. "
Describe long term potentiation (LTP)
Long lasting facilitation of synaptic transmission. Chain of neurones becomes more ingrained. Learned circuits, ingrained, easier to remember for next time, becomes more permanent. "Riding a bike"
____ and ____ regions of the brain are activated when we are encoding information that we will later remember.
Prefrontal, medial temporal
The _____ is arguably the most important brain structure in long term memory, featuring memory encoding
When memory is consolidated, it is moved from the _____ to the _____
Damage to the MTL can cause ______
memory loss, the MTL is crucial to memory creation
_____ memories are dependant on the ____ for storage
________ memories are stored somewhere outside the ____ (aka somewhere different!)
Patient HM had his ____ removed, and describe his experience
severe antereograde amnesia, could make new memories, short term memory (conditioning, priming e.t.c.) intact. Implicit memory intact.
Electrical stimulation of _____ enabled some patients to recall information that they could not previously recall.
Is there evidence to suggest that there is still traces of memories evident for 'forgotten memories'? Discuss and extrapolate.
Yes, subjects remembered forgotten noun-number pairs better, indicating some element of the 'forgotten' memory remains.
