recommendations! Published in 2017 at "Neurobiology of Learning and Memory"

DOI: 10.1016/j.nlm.2017.08.010

Abstract: HighlightsNetwork oscillatory activity during memory processing was investigated.Encoding and retrieval of context memory yielded similar activity patterns.Drugs that block memory retrieval caused distinct changes to activity patterns. ABSTRACT Memory retrieval requires coordinated intra‐ and inter‐regional… read more here.
