Theta and Gamma Oscillations Predict Encoding and Retrieval of Declarative Memory
TLDR
It is proposed that the theta activity is directly engaged in mnemonic operations and the increase in neuronal synchronization in the gamma band in occipital areas may result in a stronger drive to subsequent areas, thus facilitating both memory encoding and retrieval.
Declarative memory consolidation in humans: a prospective functional magnetic resonance imaging study.
TLDR
Over the course of the entire study, hippocampal activity for correct confident recognition continued to decrease, whereas activity in a ventral medial prefrontal region increased, which may prompt a revision of classical consolidation theory, incorporating a transfer of putative linking nodes from hippocampal to prelimbic prefrontal areas.
Sustained Neural Activity Patterns during Working Memory in the Human Medial Temporal Lobe
TLDR
This work exploits intracranial EEG to identify WM-specific sustained activity patterns with the highest temporal and spatial resolution currently available in humans, and shows that these patterns depend on WM load.
Neuronal substrates of sensory gating within the human brain
Human memory formation is accompanied by rhinal–hippocampal coupling and decoupling
TLDR
Recorded depth-EEG from within the MTL of epilepsy patients performing a memorization task suggested that effective declarative memory formation is accompanied by a direct and temporarily limited cooperation between both MTL substructures.
Stress-Related Noradrenergic Activity Prompts Large-Scale Neural Network Reconfiguration
TLDR
It is revealed that noradrenergic activation during acute stress results in prolonged coupling within a distributed network that integrates information exchange between regions involved in autonomic-neuroendocrine control and vigilant attentional reorienting.
