Agonistic effects of the opioid buprenorphine on the nociceptin/OFQ receptor
The nociceptin/orphanin FQ (N/OFQ) receptor (e.g. the human ortholog ORL1) has been shown to be pharmacologically distinct from classic opioid receptors. Recently, we have identified buprenorphine asExpand

The novel antiepileptic drug levetiracetam (ucb L059) induces alterations in GABA metabolism and turnover in discrete areas of rat brain and reduces neuronal activity in substantia nigra pars
Levetiracetam ((S)-alpha-2-oxo-pyrrolidine acetamide, ucb L059) is a novel anticonvulsant drug presently in clinical development. Its mechanism of action is unknown although a recently novel specificExpand

Tramadol increases extracellular levels of serotonin and noradrenaline as measured by in vivo microdialysis in the ventral hippocampus of freely-moving rats
Tramadol is an atypical opioid with monoamine re-uptake inhibition properties. The aim of the current study was to compare, using in vivo microdialysis, the effect of tramadol on extracellularExpand

Effects of pentylenetetrazol on GABA receptors expressed in oocytes of Xenopus laevis: extra- and intracellular sites of action
The convulsive agent pentylenetetrazol (PTZ) antagonized gamma-aminobutyric acid (GABA)-induced membrane currents on RNA-injected Xenopus oocytes with both extra- and intracellular applications. WithExpand

Striking differences in proconvulsant-induced alterations of seizure threshold in two rat models.
During drug development, seizure threshold tests are widely used to identify potential proconvulsant activity of investigational drugs. The most commonly used tests in this respect are the timedExpand

The anticonvulsant gabapentin decreases firing rates of substantia nigra pars reticulata neurons.
Gabapentin is a novel anti-epileptic drug which enhances GABA (gamma-aminobutyric acid) turnover in certain brain regions, including substantia nigra. However, the functional consequences of GABAExpand

Kindling causes persistent in vivo changes in firing rates and glutamate sensitivity of central piriform cortex neurons in rats
The present experiments were undertaken to study whether amygdala kindling induces persistent alterations in the functional status of neurons of the central piriform cortex, a subregion of theExpand

Effects of the epileptogenic agent bicuculline methiodide on membrane currents induced byN-methyl-d-aspartate and kainate (oocyte;Xenopus laevis)
The actions of bicuculline methiodide (BIC) on N-methyl-D-aspartate (NMDA)- and kainate (KA)-activated ion channels were studied using Xenopus oocytes, previously microinjected with RNA from ratExpand

Extracellular single‐unit recordings of piriform cortex neurons in rats: Influence of different types of anesthesia and characterization of neurons by pharmacological manipulation of serotonin
In epilepsy research, there is a growing interest in the role of the piriform cortex (PC) in the development and maintenance of limbic kindling and other types of limbic epileptogenesis leading toExpand

Modulation of spinal nociception by GluR5 kainate receptor ligands in acute and hyperalgesic states and the role of gabaergic mechanisms
GluR5 receptors modulate spinal nociception, however, their role in nociceptive hypersensitivity remains unclear. Using behavioural and electrophysiological approaches, we have investigated severalExpand
