Reverse replay of hippocampal place cells is uniquely modulated by changing reward (2016, unknown): “A second functional mechanism can be envisaged given recent reports that hippocampal dopamine can transform reverse order cell firing, which normally results in long-term depression (LTD) into long-term potentiation (LTP) at short delays consistent with the interspike intervals observed in replay (Z”
Frontiers in Synaptic Neuroscience Synaptic Neuroscience (unknown): “…processes, namely fear-conditioning (Bissiere et al., 2003), rapid learning (Zhang et al., 2009), reward-based learning (Pawlak and Kerr, 2008; Zhang et al., 2009), cognitive performance (Couey et al., 2007), but also pathological states (Shen et al., 2008) (for modeling approaches see: Baras…”
Pyramidal Neuron Conductance State Gates Spike-Timing-Dependent Plasticity (2010, background): “-Adrenergic receptor activation rescues deficit in t-LTP A prominent feature of the intact cortex, the impact of which on STDP is only beginning to be explored, is neuromodulation (Seol et al., 2007; Zhang et al., 2009).”
Functional Requirements for Reward-Modulated Spike-Timing-Dependent Plasticity (2010, background): “…study in hippocampal cell cultures indicates, moreover, that an increase in dopamine level can convert the LTD (post-before-pre) component of STDP into LTP, whereas the LTP (pre-before-post) component remains unchanged in amplitude but changes its coincidence requirements (Zhang et al., 2009).”
Neuromodulated Spike-Timing-Dependent Plasticity, and Theory of Three-Factor Learning Rules (2016, methodology): “In the absence of extracellular Mg2+, LTP is observed at normal dopamine levels (instead of LTD), but LTP induction is not possible if D1/D5 dopamine receptors are blocked (Kerr and Wickens, 2001).”
Eligibility Traces and Plasticity on Behavioral Time Scales: Experimental Support of NeoHebbian Three-Factor Learning Rules (2018, background): “Thus dopamine broadens the STDP window for LTP into the post-before-pre regime (Zhang et al., 2009; Pawlak et al., 2010).”
A History of Spike-Timing-Dependent Plasticity (2011, result): “As shown by the teams of Jason Kerr, Alfredo Kirkwood, and Guo-qiang Bi, STDP is also under powerful neuromodulatory control (Seol et al., 2007; Pawlak and Kerr, 2008; Zhang et al., 2009; Pawlak et al., 2010).”
Neuronal Reward and Decision Signals: From Theories to Data. (2015, background): “The released dopamine influences the plasticity between conjointly active presynaptic and postsynaptic neurons in a three factor Hebbian learning scheme (FIGURE 17, B AND C) involving striatum, frontal cortex, and other structures in which appropriate dopamine dependent plasticity is found (82, 194,”
Replay Comes of Age. (2017, methodology): “Increasingly, probabilistic decoding methods are being used for measuring replay phenomena (Davidson et al. 2009, Zhang et al. 1998).”
The spike timing dependence of plasticity (2012, background): “Neuromodulation can also alter the shape of STDP rules, including converting Hebbian STDP into anti-Hebbian LTD (Shen et al., 2008; Zhang et al., 2009, Zhao and Tzounopoulos, 2011).”
Event Timing in Associative Learning: From Biochemical Reaction Dynamics to Behavioural Observations (2012, background): “, in vertebrate brain slices, no less than 20 pre-post synaptic action potential pairings are necessary to obtain only ,10% potentiation of synaptic strength [56].”
Stable Learning in Stochastic Network States (2012, background): “…in both vertebrates and invertebrates that STDP is modulated by neuromodulators (Seol et al., 2007; Pawlak and Kerr, 2008; Shen et al., 2008; Zhang et al., 2009; Pawlak et al., 2010; S. Cassenaer, and G. Laurent, personal communication), which are known to be key factors in memory retention…”
Spatio-Temporal Credit Assignment in Neuronal Population Learning (2011, unknown): “This matches with experimental observations revealing that the polarity and magnitude of STDP can in fact be regulated by neuromodulators such as dopamine, acetylcholine or noradrenaline which may even revert the sign of the synaptic change [10,21,22], e.”
