About sleep's role in memory. (2013, background): “, the development of late LTP from early LTP, is assumed to require a “tagging” of synapses due to associative heterosynaptic stimulation within a certain time window ( 30 min) following LTP induction (419).”
How can memories last for days, years, or a lifetime? Proposed mechanisms for maintaining synaptic potentiation and memory (2019, background): “It also appears likely that the synaptic tag identified as being necessary for “capture” of PRPs, essential for late LTP (Frey and Morris 1997, 1998) should be persistently and selectively set at strong synapses in order to allow periodic reinforcing capture of PRPs, in vivo or in active slice…”
Requirement of β‐adrenergic receptor activation and protein synthesis for LTP‐reinforcement by novelty in rat dentate gyrus (2003, background): “1999), NA seems to be important for the induction and maintenance of LTP in the DG (see also Stanton & Sarvey, 1985; Frey & Morris 1998; Swanson-Park et al. 1999).”
Cellular and Systems Consolidation of Declarative Memory (2017, background): “The importance of NMDA-receptor dependent LTP for memory was shown in a seminal study by Richard Morris, in which the inhibition of NMDA-receptors in the hippocampus prevented the induction of LTP and led to a memory deficit in the spatial watermaze task (Morris et al. 1982).”
The Formation of Recent and Remote Memory Is Associated with Time-Dependent Formation of Dendritic Spines in the Hippocampus and Anterior Cingulate Cortex (2009, background): “Indeed, how the hippocampus manages to activate the experience-relevant set of cortical neurons is still a matter of debate, although potential mechanisms, including synaptic tagging, have been proposed (Frey and Morris, 1998; Martin and Kosik, 2002).”

Mechanisms of CaMKII action in long-term potentiation (2012, background): “, which is stimulated by brain-derived growth factor and dopamine and involves the selective targeting of newly synthesized proteins to the synapses that have undergone LT”
States of curiosity modulate hippocampus-dependent learning via the dopaminergic circuit (2014, unknown): “Accordingly, several models (Frey and Morris, 1998; Lisman and Grace, 2005; Lisman et al., 2011; Redondo and Morris, 2011; Shohamy and Adcock, 2010) propose that stabilization of learning-induced hippocampal plasticity depends on dopaminergic neuromodulation, in addition to synaptic activity.”
