True or False: All mammals show REM and nonREM sleep

true

A solution or type of sleep for (partially) maintaining awareness while asleep, as seen by many animals, is known as _____ (4 words)

unihemispheric slow wave sleep

Permanent engrams are stored in the _____, rather than the hippocampus

cortex

neocortex

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

true

True or False: Different neurons are replayed for the "left sound" and the "right sound" during memory consolidation
