unihemispheric slow wave sleep
Permanent engrams are stored in the _____, rather than the hippocampus

True or False: With long term memories, you can bypass the hippocampus and instead use only the neocortex
true
The physical basis or neural process of memories is called an ____
engram
True or False: If information is still in your short term memory (ie. consolidation has not happened), retrieval processes will use the hippocampus
true
Specific neurons in the hippocampus that selectively code spatial information are known as _____ cells
place
The entorhinal cortex has ___ cells, instead of place cells
grid
During _____ sleep, sequential coded info from place cells is replayed as if the brain is rehearsing what it has learned
nonREM
NREM
During sleep replay, cortical inputs are (blank) while hippocampal outputs are (blank)
non sequential; sequential
True or False: During memory consolidation, the hippocampus and cortex "talk" to each other in order to transfer information from short term memory into long term memory
true
True or False: Odor cues played during learning as well as NREM sleep can prompt memory consolidation
