(2008, background): “Synaptic tagging and capture are 404 Cell 135, October 31, 2008 ©2008 Elsev also observed with LTD, and in fact, crosscapture has been reported between LTP and LTD: induction of L-LTP in one synaptic pathway can convert E-LTD to L-LTD in another pathway, and vice versa (Sajikumar and Frey, 2004).”
The dendritic branch is the preferred integrative unit for protein synthesis-dependent LTP (2011, background): “It is well established that this L-LTP is dependent on dopamine receptor 1 (D1R) class activation (Frey et al., 1990, 1991; O’Carroll and Morris, 2004; Otmakhova and Lisman, 1996; Sajikumar and Frey, 2004; Sajikumar et al., 2008; Smith et al., 2005; Swanson-Park et al., 1999) and the PKA pathway (Ab”
Synaptic consolidation: an approach to long-term learning (2011, methodology): “Same as (d) but the inhibitor is applied during a period that starts 25 min after the strong tetanus, and lasts until 1 h after the weak tetanus. be the case in slice experiments where tags are reset (Sajikumar and Frey 2004b), experiments that are not directly captured by the TagTriC model.”

Elements of a neurobiological theory of hippocampal function: the role of synaptic plasticity, synaptic tagging and schemas (2006, background): “Sajikumar & Frey (2004a) began by confirming earlier observations that the application of low-frequency stimulation (LFS) very shortly after the induction of E-LTP reset the potentiation back to baseline (Staubli & Lynch, 1990; Staubli & Chun, 1996).”
Synaptic Consolidation: From Synapses to Behavioral Modeling (2015, background): “Experimental work (Frey et al., 1990; Sajikumar and Frey, 2004b; Lisman and Grace, 2005) has linked the production of PRP and the maintenance of memory to the presence of neuromodulators such as dopamine.”
Making memories last: the synaptic tagging and capture hypothesis (2010, background): “Cross-capture experiments point to the existence of a common pool of PRPs that is made available after the induction of persistent forms of LTP and LTD from which all tagged synapses can benefit regardless of the direction of their synaptic chang”
