Reactivation-induced motor skill modulation does not operate at a rapid micro-timescale level by Jasmine Herszage, Marlene Bönstrup, Leonardo G. Cohen, Nitzan Censor

“…Abstract Abundant evidence shows that consolidated memories are susceptible to modifications following their reactivation. Processes of memory consolidation and reactivation-induced skill modulation have been commonly documented after hours or days. …”

Sleep-promoting neurons remodel their response properties to calibrate sleep drive with environmental demands. by Stephane Dissel, Markus K Klose, Bruno van Swinderen, Lijuan Cao, Melanie Ford, Erica M Periandri, Joseph D Jones, Zhaoyi Li, Paul J Shaw

“…To understand how animals match sleep need with environmental demands, we used live-brain imaging to examine the physiological response properties of the dorsal fan-shaped body (dFB) following interventions that modify sleep (sleep deprivation, starvation, time-restricted feeding, memory consolidation) in Drosophila. We report that dFB neurons change their physiological response-properties to dopamine (DA) and allatostatin-A (AstA) in response to different types of waking. …”

The Medial Prefrontal Cortex and Fear Memory: Dynamics, Connectivity, and Engrams by Lucie Dixsaut, Johannes Gräff

“…In this review, we summarize these findings, relate them to the functional importance of the mPFC connectivity, and discuss the role of the mPFC during memory consolidation with respect to the different theories of memory storage. …”

Awake ripples enhance emotional memory encoding in the human brain by Haoxin Zhang, Ivan Skelin, Shiting Ma, Michelle Paff, Lilit Mnatsakanyan, Michael A. Yassa, Robert T. Knight, Jack J. Lin

“…Abstract Enhanced memory for emotional experiences is hypothesized to depend on amygdala-hippocampal interactions during memory consolidation. Here we show using intracranial recordings from the human amygdala and the hippocampus during an emotional memory encoding and discrimination task increased awake ripples after encoding of emotional, compared to neutrally-valenced stimuli. …”

Systemic injection of an H4 receptor agonist induces a decrease in CREB and pCREB levels in the cerebellar vermis and prefrontal cortex in mice by C.E.M. Fernandes, K.R. Serafim, A.C.L. Gianlorenço, R. Mattioli

“…In the present study, the aim was to verify if intraperitoneal (ip) injection of VUF-8430 (500 ng/kg) in mice affects the synthesis of proteins required for memory consolidation processes by activating the phosphorylation of CREB (pCREB) in classical structures linked to emotional memory (prefrontal cortex, amygdala, and hippocampus) and the cerebellar vermis, a structure that has also been recently implicated in emotional memory. …”

A new player in the ‘synaptopathy’ of Alzheimer’s disease - Arc/Arg 3.1 by Talitha Lynn Kerrigan, Andrew D. Randall

“…Accumulating evidence supports the functional importance of the early-expression activity-regulated cytoskeletal (Arc) gene in regulating memory consolidation. Interestingly, AD patients express anomalously high levels of Arc protein. …”

The role of serotonin in cognitive function: evidence from recent studies and implications for understanding depression. by Cowen, P, Sherwood, A

“…FINDINGS: The most consistent observation following manipulation of serotonin levels in humans is that low extracellular 5-HT levels are associated with impaired memory consolidation. Preclinical data show that agonism and antagonism at specific 5-HT receptors can exert effects in animal models of cognition. …”

Network state-dependent inhibition of identified hippocampal CA3 axo-axonic cells in vivo. by Viney, T, Lasztoczi, B, Katona, L, Crump, MG, Tukker, J, Klausberger, T, Somogyi, P

“…We hypothesize that inhibition of AACs, and the resulting subcellular redistribution of inhibition from the axon initial segment to other pyramidal cell domains, is a necessary condition for the emergence of sharp waves promoting memory consolidation.…”

High-throughput analysis of in-vitro LFP electrophysiological signals: a validated workflow/software package by Tsakanikas, P, Sigalas, C, Rigas, P, Skaliora, I

“…Synchronized brain activity in the form of alternating epochs of massive persistent network activity and periods of generalized neural silence, has been extensively studied as a fundamental form of circuit dynamics, important for many cognitive functions including short-term memory, memory consolidation, or attentional modulation. A key element in such studies is the accurate determination of the timing and duration of those network events. …”

Endogenous memory reactivation during sleep in humans is clocked by slow oscillation-spindle complexes by Schreiner, T, Petzka, M, Staudigl, T, Staresina, BP

“…Sleep is thought to support memory consolidation via reactivation of prior experiences, with particular electrophysiological sleep signatures (slow oscillations (SOs) and sleep spindles) gating the information flow between relevant brain areas. …”

Is the Papez circuit the location of the elusive episodic memory engram? by Steven Hall, PhD, MSc

“…Further, by considering the microcircuits observed in the medial temporal lobe structures forming Papez’ circuit, the paper establishes the neural mechanisms behind the required functions of sensory information storage and recall, pattern completion, pattern separation, and memory consolidation. The paper shows that Papez’ circuit has the necessary connectivity to gather the various elements of an episodic memory occurring within Pöppel’s experienced time or “quantum of experience”. …”
