The effect of dopaminergic D1 receptor blockade on the expression of long-term potentiation (LTP) was investigated in the rat hippocampal CA1 region in vitro by extracellular recordings (by measuring the population spike amplitude and the field EPSP). The presence of the very selective D1 receptor blocker SCH 23390 at a concentration of 0.1 microM during tetanization with 3 trains of 100 impulses (100 Hz) resulted in a prevention of late LTP stages (greater than 1-2 h). When SCH 23390 was added… Expand
Activation of dopamine D1 receptors enhances long-term depression of synaptic transmission induced by low frequency stimulation in rat hippocampal CA1 neurons
TLDR
Results indicate that DA D1 receptors play an important role in the modulation of LFS-induced LTD in rat hippocampal CA1 neurons. Expand
Dopamine transporter blockade increases LTP in the CA1 region of the rat hippocampus via activation of the D3 dopamine receptor.
TLDR
The results suggest that either endogenously released dopamine (facilitated by DAT blockade) or exogenously applied dopamine agonist can act to increase LTP in the CA1 of the hippocampus via activation of the D3 subtype of dopamine receptor. Expand
Regulation of depotentiation and long-term potentiation in the dentate gyrus of freely moving rats by dopamine D2-like receptors.
TLDR
A specific role for dopamine D2-like receptors in the regulation of both depotentiation and LTP in vivo is suggested and an important and novel insight is offered as to the involvement of these receptors in processes related to learning and memory. Expand
A double dissociation within the hippocampus of dopamine D1/D5 receptor and β-adrenergic receptor contributions to the persistence of long-term potentiation
TLDR
There is a double dissociation of the catecholamine modulation of long-term potentiation between CA1 and the dentate gyrus, suggesting that long- term potentiation in these brain areas may be differentially consolidated according to the animal's behavioural state. Expand
Norepinephrine reverses N-methyl-d-aspartate-mediated inhibition of long-term potentiation in rat hippocampal slices
TLDR
The effect of trans-amino-1,3-cyclopentanedicarboxylic acid, norepinephrine and acetylcholine on this NMDA-mediated LTP inhibition using extracellular recordings from in vitro rat hippocampal slices suggests the involvement of alpha 1-adrenergic receptors. Expand
Depotentiation in the dentate gyrus of freely moving rats is modulated by D1/D5 dopamine receptors.
TLDR
Results indicate that whereas D1/D5 receptor activation may not be a critical factor in LTP induction in the DG, a differential role for these receptors in the expression of depotentiation, in this hippocampal subfield, may exist. Expand
In utero cocaine exposure decreases dopamine D1 receptor modulation of hippocampal long-term potentiation in the rabbit
TLDR
Tetanization during exposure to the D1 antagonist SCH-23390 resulted in a long lasting potentiation in animals prenatally exposed to cocaine while the potentiation of control slices returned to baseline. Expand
Modulation of extracellular monoamine transmitter concentrations in the hippocampus after weak and strong tetanization of the perforant path in freely moving rats
TLDR
The microdialysis method is implemented to study the concentrations and temporal dynamics of such neuromodulators like NA, serotonin (5-HT) and dopamine (DA) during LTP, which may support discriminative processing of incoming information in the hippocampus. Expand
D1/D5 Dopamine Receptor Activation Increases the Magnitude of Early Long-Term Potentiation at CA1 Hippocampal Synapses
TLDR
D dopamine produces a synapse-specific enhancement of early LTP through D1/D5 receptors and cAMP, indicating that dopamine should be able to modulate activity-dependent synaptic plasticity. Expand
Dopamine-Mediated Disinhibition in the CA1 Region of Rat Hippocampus via D3 Receptor Activation
TLDR
Investigation of the actions of both cocaine and dopamine receptor agonists in the CA1 region indicates that the activation of D3 receptors by endogenously released dopamine, especially under conditions of transporter blockade, may significantly impact the processing of synaptic information through the stratum radiatum layer of the hippocampus.

Dopaminergic antagonists prevent long-term maintenance of posttetanic LTP in the CA1 region of rat hippocampal slices
TLDR
The observations suggest that dopaminergic influences during and immediately after tetanization at least additionally contribute to the induction of postsynaptic mechanisms subserving a late, long-lasting maintenance of potentiation. Expand
Muscarinic receptor activation facilitates the induction of long-term potentiation (LTP) in the rat dentate gyrus
TLDR
Activation of M1 receptors can facilitate the induction of LTP, and bath application of two different concentrations of muscarine produced two different effects on evoked responses in the dentate gyrus of rat hippocampal slices. Expand
Agonists of cholinergic and noradrenergic receptors facilitate synergistically the induction of long-term potentiation in slices of rat visual cortex
TLDR
It is suggested that the agonists of both receptor systems enhanced the depolarizing response to the tetanus and increased NMDA receptor-gated conductances during this response also accounts for the facilitatory effects which ACh and NA have on use-dependent synaptic plasticity in the developing visual cortex. Expand
Naloxone blocks the induction of long-term potentiation in the lateral but not in the medial perforant pathway in the anesthetized rat
TLDR
It is suggested that activation of naloxone-sensitive receptors is necessary for the full expression of LTP in the lateral perforant pathway. Expand
The duration of long-term potentiation in the CA1 region of the hippocampal slice preparation
TLDR
The slice preparation is proposed that the investigation of mechanisms of a postulated late phase of LTP if appropriate conditions are used and the smaller field-EPSP values necessary to evoke near-threshold pop-spikes demonstrate an E-S potentiation (left-shift) at least in the low-intensity range. Expand
Reduction of long‐term potentiation in the dentate gyrus of the rat following selective depletion of monoamines.
TLDR
Results show that monoamines can modulate long‐term changes in synaptic function in the dentate gyrus, and suggest that 5‐HT is more potent in this respect than NA, and the effect of monoamine depletion on granule cell excitability was investigated. Expand
2-Amino-4-phosphonobutyrate selectively eliminates late phases of long-term potentiation in rat hippocampus
TLDR
Data suggest that besides the obligatory NMDA receptor activation an APB-sensitive component expressed during and after tetanization is a necessary step for subsequent mechanisms enabling the late maintenance of LTP. Expand
Long‐term potentiation and depression of synaptic responses in the rat hippocampus: localization and frequency dependency.
TLDR
The results suggest that potentiated and heterosynaptic depression arise from different mechanisms, and that potentiation is confined to the set of terminals activated by a conditioning train, whereas the depression is generalized to the whole neurone. Expand
Polymyxin B, an inhibitor of protein kinase C, prevents the maintenance of synaptic long-term potentiation in hippocampal CA1 neurons
TLDR
Results provide direct evidence that the PKC activation is not essential for the initial phase of LTP, but is a necessary condition for a medium and a late, protein synthesis-dependent phase in this monosynaptic pathway, i.e. for the maintenance of synaptic LTP. Expand
NMDA application potentiates synaptic transmission in the hippocampus
TLDR
This model predicts that application of a large depolarizing dose of NMDA should be sufficient to evoke long-term potentiation, and proposes that LTP has two components, a short-term, decremental component which can be mimicked by NMDA receptor activation, and a long-lasting, non-decremental components which, in addition to requiring activation ofNMDA receptors, requires stimulation of presynaptic afferents.
