Hippocampal replay in the awake state: a potential physiological substrate of memory consolidation and retrieval (2011, background): “Furthermore, novelty leads to a dopamine-dependent reduction in the threshold for LTP induction at the CA3-CA1 synaps”
Requirement of β‐adrenergic receptor activation and protein synthesis for LTP‐reinforcement by novelty in rat dentate gyrus (2003, background): “A recent study conducted in hippocampal area CA1 found a dopamine-dependent facilitation of LTP induction by preceding novelty-exploration but did not examine the influence of pre-tetanic novelty-exposure on LTP maintenance (Li et al. 2003).”
Backpropamine: training self-modifying neural networks with differentiable neuromodulated plasticity (2018, background): “This neuromodulation of plasticity, which involves several chemicals (particularly dopamine; Calabresi et al. 2007; He et al. 2015; Li et al. 2003; Yagishita et al. 2014), plays an important role in learning and adaptation (Molina-Luna et al., 2009; Smith-Roe & Kelley, 2000; Kreitzer & Malenka,…”

Reward-motivated learning: mesolimbic activation precedes memory formation. (2006, background): “D1/D5 dopamine receptor activation increases the magnitude of early long-term potentiation at CA1 hippocampal synapses.”
State Based Model of Long-Term Potentiation and Synaptic Tagging and Capture (2009, background): “Although there is some evidence that decay from the `-LTP state is an active process rather than passive decay [8, 35], detailed knowledge of this is still lacking, so we did not attempt to include this.”
Synaptic Consolidation: From Synapses to Behavioral Modeling (2015, background): “Because exploration of an OF for at least 5 min is known to trigger dopamine release in the rat hippocampus (Li et al., 2003), it has been hypothesized earlier that these behavioral results could potentially be related to the transformation of tagged synapses from early LTP to late LTP through…”
ReviewThe Hippocampal-VTA Loop : Controlling the Entry of Information into Long-Term Memory (2005, unknown): “Activation of this kinase, in turn, acts to inhibit phosphatase activity and thereby enhances the (Figure 3A) is noteworthy because of the use of a second input pathway that was not tetanized; the stability phosphorylation of CaMKII (Blitzer et al., 1998), a molecule that is necessary and sufficient”
Synaptic consolidation: an approach to long-term learning (2011, background): “If however, the rat is placed in a novel environment before the inhibitory avoidance training, a situation which is known to release dopamine (Li et al. 2003; Kentros et al. 2004), the rat learns to stay on the platform and still remembers this after 24 h.”
The principal features and mechanisms of dopamine modulation in the prefrontal cortex. (2004, background): “Similar long-lasting effects of DA or D1 receptor agonists have been reported in vivo (Yang and Mogenson, 1984; Gribkoff and Ashe, 1984; Li et al., 2003; Williams and Millar, 1990b).”
Reward-related fMRI activation of dopaminergic midbrain is associated with enhanced hippocampus-dependent long-term memory formation (2005, background): “Rats freely moving in a novel spatial environment have a reduced threshold for LTP induction in a narrow time window, and this facilitation of LTP in the CA1 region can be blocked by D1/D5 receptor antagonists (Li et al., 2003).”

Sleep facilitates memory by blocking dopamine neuron mediated forgetting (2015, unknown): “DA is known to regulate various types of plasticity in mammals (Li et al., 2003; Huang et al., 2004; Centonze et al., 2001).”
