The somata of pairs forming interlaminar L4-to-L5A connections were located predominantly close to or directly under the barrel-septum wall in layer 4. Superposition of spiny stellate axon arbors and L5A pyramidal cell dendritic arbors suggested an innervation domain underneath an L4 barrel wall. Functionally, the L4-to-L5A connections were of high reliability and relatively low efficacy, with a unitary EPSP amplitude of 0.6 mV, and the connectivity was moderately high (one in seven pairs tested was connected). The EPSP amplitude was weakly depressing (paired-pulse ratio of approximately 0.8) during repetitive presynaptic action potentials at 10 Hz. The existence of monosynaptic L4-to-L5A connections indicates that the specific "lemniscal" thalamic input from the ventro-basal nucleus of the thalamus to the cortex and the more unspecific "paralemniscal" afferent thalamic projections from the posterior medial nucleus of the thalamus merge already at an initial stage of cortical signal processing. These monosynaptic connections establish a monosynaptic coupling of the input to the cortex and its output, thereby effectively bypassing the supragranular layers. 000045088 536__ $$0G:(DE-Juel1)FUEK255$$2G:(DE-HGF)$$aNeurowissenschaften$$cL01$$x0 000045088 588__ $$aDataset connected to Web of Science, Pubmed 000045088 650_2 $$2MeSH$$aAfferent Pathways: cytology 000045088 650_2 $$2MeSH$$aAfferent Pathways: physiology 000045088 650_2 $$2MeSH$$aAnimals 000045088 650_2 $$2MeSH$$aElectric Stimulation: methods 000045088 650_2 $$2MeSH$$aExcitatory Postsynaptic Potentials: physiology 000045088 650_2 $$2MeSH$$aExcitatory Postsynaptic Potentials: radiation effects 000045088 650_2 $$2MeSH$$aImage Processing, Computer-Assisted: methods 000045088 650_2 $$2MeSH$$aLysine: analogs & derivatives 000045088 650_2 $$2MeSH$$aLysine: metabolism 000045088 650_2 $$2MeSH$$aNeural Networks (Computer) 000045088 650_2 $$2MeSH$$aNeurons: classification 000045088 650_2 $$2MeSH$$aNeurons: cytology 000045088 650_2 $$2MeSH$$aNeurons: physiology 000045088 650_2 $$2MeSH$$aPatch-Clamp Techniques: methods 000045088 650_2 $$2MeSH$$aRats 000045088 650_2 $$2MeSH$$aRats, Wistar 000045088 650_2 $$2MeSH$$aReaction Time: physiology 000045088 650_2 $$2MeSH$$aReaction Time: radiation effects 000045088 650_2 $$2MeSH$$aSomatosensory Cortex: cytology 000045088 650_2 $$2MeSH$$aSynapses: physiology 000045088 650_7 $$056-87-1$$2NLM Chemicals$$aLysine 000045088 650_7 $$0576-19-2$$2NLM Chemicals$$abiocytin 000045088 650_7 $$2WoSType$$aJ 000045088 65320 $$2Author$$abarrel cortex 000045088 65320 $$2Author$$asynaptic transmission 000045088 65320 $$2Author$$alayer 4 000045088 65320 $$2Author$$alayer 5A 000045088 65320 $$2Author$$acortical microcircuits 000045088 65320 $$2Author$$apyramidal cell 000045088 7001_ $$0P:(DE-HGF)0$$aRoth, A.$$b1 000045088 7001_ $$0P:(DE-HGF)0$$aSakmann, B.$$b2 000045088 773__ $$0PERI:(DE-600)1475274-8$$a10.1523/JNEUROSCI.5227-04.2005$$gVol. 25, p. 3431 - 3423$$p3431 - 3423$$q25<3431 - 3423$$tThe @journal of neuroscience$$v25$$x0270-6474$$y2005 000045088 8567_ $$uhttp://dx.doi.org/10.1523/JNEUROSCI.5227-04.2005 000045088 8564_ $$uhttps://juser.fz-juelich.de/record/45088/files/3423.full.pdf$$yOpenAccess 000045088 8564_ $$uhttps://juser.fz-juelich.de/record/45088/files/3423.full.pdf?subformat=pdfa$$xpdfa$$yOpenAccess 000045088 909CO $$ooai:juser.fz-juelich.de:45088$$pdnbdelivery$$pdriver$$pVDB$$popen_access$$popenaire 000045088 9131_ $$0G:(DE-Juel1)FUEK255$$bLeben$$kL01$$lFunktion und Dysfunktion des Nervensystems$$vNeurowissenschaften$$x0 000045088 9141_ $$y2005 000045088 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000045088 915__ $$0StatID:(DE-HGF)0010$$aJCR/ISI refereed 000045088 9201_ $$0I:(DE-Juel1)VDB54$$d31.12.2006$$gIME$$kIME$$lInstitut für Medizin$$x0 000045088 970__ $$aVDB:(DE-Juel1)67346 000045088 980__ $$aVDB 000045088 980__ $$aConvertedRecord 000045088 980__ $$ajournal 000045088 980__ $$aI:(DE-Juel1)INB-3-20090406 000045088 980__ $$aUNRESTRICTED 000045088 9801_ $$aFullTexts 000045088 981__ $$aI:(DE-Juel1)INB-3-20090406
