Serotonin reduces synaptic excitation in the superficial medial entorhinal cortex of the rat via a presynaptic mechanismD Schmitz
Institute of Physiology at the Charite, Department of Neurophysiology, Humboldt University Berlin, Tucholskystrasse 2, 10117 Berlin, Germany
J Physiol 508:119-29. 1998..6. We conclude that serotonin potently suppresses excitatory synaptic transmission via 5-HT1A receptors in layers II and III of the medial entorhinal cortex by a presynaptic mechanism...
Potent depression of stimulus evoked field potential responses in the medial entorhinal cortex by serotoninD Schmitz
Institute of Physiology at the Charite, Department of Neurophysiology, Humboldt University Berlin, Tucholskystrasse 2, 10117 Berlin, Germany
Br J Pharmacol 128:248-54. 1999..7. We conclude that physiological concentrations of serotonin potently suppresses excitatory synaptic transmission in the superficial entorhinal cortex by a presynaptic mechanism...
Munc13-2 differentially affects hippocampal synaptic transmission and plasticityJ Breustedt
Neurowissenschaftliches Forschungszentrum, Charite Universitatsmedizin Berlin, 10117 Berlin, Germany
Cereb Cortex 20:1109-20. 2010..In contrast, transmission at 3 other types of hippocampal synapses, Schaffer-collateral, associational-commissural, as well as inhibitory synapses onto CA3 pyramidal neurons was unaffected by the loss of Munc13-2...
Carbachol-induced changes in excitability and [Ca2+]i signalling in projection cells of medial entorhinal cortex layers II and IIIT Gloveli
Institute of Physiology at the Charite, Department of Neurophysiology, Humboldt University, Berlin, Germany
Eur J Neurosci 11:3626-36. 1999..In conclusion, we present evidence for significant differences in the [Ca2+]i regulation between layer II stellate and layer III pyramidal cells of the medial EC...
Laminar difference in GABA uptake and GAT-1 expression in rat CA1D Engel
Institut fur Physiologie der Charite, Humboldt Universitat, Tucholskystrasse 2, 10117 Berlin, Germany
J Physiol 512:643-9. 1998..Our findings suggest that this laminar difference is caused by a lower expression of GAT-1 in interneurons in stratum oriens than in stratum radiatum/lacunosum-moleculare...
Systemic administration of the phencyclidine compound MK-801 affects stimulus-induced field potentials selectively in layer III of rat medial entorhinal cortexT Gloveli
Institute for Physiology at the Charite, Department of Neurophysiology, Humboldt University Berlin, Germany
Neurosci Lett 221:93-6. 1997..Since the principal cells of layer III project directly to area CA1 and the subiculum, the selective effects of MK-801 may have implications for the transfer of information to the hippocampus...
Interaction between superficial layers of the entorhinal cortex and the hippocampus in normal and epileptic temporal lobeT Gloveli
Institute of Physiology at the Charite, Department of Neurophysiology, Humboldt University Berlin, Germany
Epilepsy Res 32:183-93. 1998....
Properties of entorhinal cortex deep layer neurons projecting to the rat dentate gyrusT Gloveli
Johannes Müller Institute of Physiology at the Charité, Humboldt University, Berlin, Tucholskystrasse 2, 10117 Berlin, Germany
Eur J Neurosci 13:413-20. 2001....
Dopamine depresses polysynaptic inhibition in rat subicular neuronsJ Behr
Department of Neurophysiology, Institute of Physiology, University Hospital Charite, Humboldt University Berlin, Tucholskystr 2, Berlin, Germany
Brain Res 861:160-4. 2000..We conclude that in addition to membrane effects, DA decreases polysynaptic IPSPs by attenuating the glutamatergic drive onto subicular interneurons...
Dopamine depresses excitatory synaptic transmission onto rat subicular neurons via presynaptic D1-like dopamine receptorsJ Behr
Department of Neurophysiology, Institute of Physiology, University Hospital Charite, Humboldt University Berlin, 10117 Berlin, Germany
J Neurophysiol 84:112-9. 2000..The results indicate that DA strongly depresses the hippocampal and the entorhinal excitatory input onto subicular neurons by decreasing the glutamate release following activation of presynaptic D1-like DA receptors...
Electrophysiological properties of rat subicular neurons in vitroJ Behr
Institute of Physiology at the Charite, Department of Neurophysiology, Humboldt University Berlin, Germany
Neurosci Lett 220:41-4. 1996..Regular firing cells usually displayed a fast and a slow afterhyperpolarization following a train of action potentials, while bursting neurons present only a slow afterhyperpolarization...
Enhanced temporal stability of cholinergic hippocampal gamma oscillations following respiratory alkalosis in vitroK Stenkamp
Johannes Müller Institut für Physiologie, Humboldt Universitat Berlin, 10117 Berlin, Germany
J Neurophysiol 85:2063-9. 2001..These results suggest that changes in brain pCO(2) can have a strong influence on the temporal modulation of gamma rhythms...
Axo-axonal coupling. a novel mechanism for ultrafast neuronal communicationD Schmitz
Institute of Physiology, Charite, Humboldt University Berlin, Tucholskystr 2, 10117, Berlin, Germany
Neuron 31:831-40. 2001..Our data thus suggest that hippocampal neurons are coupled by axo-axonal junctions, providing a novel mechanism for very fast electrical communication...
Enhanced synaptic excitation-inhibition ratio in hippocampal interneurons of rats with temporal lobe epilepsyF Stief
Neurowissenschaftliches Forschungszentrum der Charité, Humboldt University Berlin, Germany
Eur J Neurosci 25:519-28. 2007..This alteration may enhance feedforward inhibition and rhythmogenesis and--together with specific changes in other interneurons--contribute to seizure susceptibility and pathological synchronization...
Alpha1E-containing Ca2+ channels are involved in synaptic plasticityJ Breustedt
Neuroscience Research Center at the Charité, Humboldt University, Schumannstrasse 20 21, 10117 Berlin, Germany
Proc Natl Acad Sci U S A 100:12450-5. 2003..Indeed, optical recordings directly show the presence and the function of alpha1E-containing VDCCs at mossy fiber terminals. Hence, a previously undescribed role for alpha1E-containing VDCCs is suggested by these results...
