Presynaptic inhibition by muscimol through GABAB receptors
The γ-aminobutyric acid type A (GABAA) receptor agonist muscimol is widely used as a tool for reducing neuronal activities particularly in experiments in vivo. At the synapse formed by the calyx of Held in the rat brainstem slice, the GABAA receptor agonist muscimol (> 10 μm) attenuated the ampli...

Presynaptic inhibition by muscimol through GABAB receptors |
| abstract |
The γ-aminobutyric acid type A (GABAA) receptor agonist muscimol is widely used as a tool for reducing neuronal activities particularly in experiments in vivo. At the synapse formed by the calyx of Held in the rat brainstem slice, the GABAA receptor agonist muscimol (> 10 μm) attenuated the amplitude of excitatory post synaptic currents (EPSCs) accompanied by an increase in the coefficient of variation of EPSCs, suggesting its presynaptic inhibitory effect. This muscimol effect was not affected by bicuculline but occluded the presynaptic inhibitory effect of the GABAB receptor agonist baclofen and was abolished by the type B GABA (GABAB) receptor-specific antagonist (+)-5,5-dimethyl-2-morpholineacetic acid (SCH 50911; 20 μm). We conclude that muscimol activates presynaptic GABAB receptors thereby attenuating synaptic transmission. |

At the synapse formed by the calyx of Held in the rat brainstem slice, the GABAA receptor agonist muscimol (> 10 μm) attenuated the amplitude of excitatory post synaptic currents (EPSCs) accompanied by an increase in the coefficient of variation of EPSCs, suggesting its presynaptic inhibitory effect. This muscimol effect was not affected by bicuculline but occluded the presynaptic inhibitory effect of the GABAB receptor agonist baclofen and was abolished by the type B GABA (GABAB) receptor-specific antagonist (+)-5,5-dimethyl-2-morpholineacetic acid (SCH 50911; 20 μm). We conclude that muscimol activates presynaptic GABAB receptors thereby attenuating synaptic transmission.</subfield></datafield><datafield tag="533" ind1=" " ind2=" "><subfield code="d">2001</subfield><subfield code="f">Blackwell Publishing Journal Backfiles 1879-2005</subfield><subfield code="7">|2001||||||||||</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">calyx of Held</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Hori, Tetsuya</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Takahashi, Tomoyuki</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">In</subfield><subfield code="t">European journal of neuroscience</subfield><subfield code="d">Oxford [u.a.] : Blackwell, 1989</subfield><subfield code="g">12(2000), 9, Seite 0</subfield><subfield code="h">Online-Ressource</subfield><subfield code="w">(DE-627)NLEJ243926383</subfield><subfield code="w">(DE-600)2005178-5</subfield><subfield code="x">1460-9568</subfield><subfield code="7">nnns</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:12</subfield><subfield code="g">year:2000</subfield><subfield code="g">number:9</subfield><subfield code="g">pages:0</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">http://dx.doi.org/10.1046/j.1460-9568.2000.00248.x</subfield><subfield code="q">text/html</subfield><subfield code="x">Verlag</subfield><subfield code="z">Deutschlandweit zugänglich</subfield><subfield code="3">Volltext</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_U</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">ZDB-1-DJB</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_NL_ARTICLE</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">12</subfield><subfield code="j">2000</subfield><subfield code="e">9</subfield><subfield code="h">0</subfield></datafield></record></collection>
