Field recordings of evoked excitatory postsynaptic potentials (pEPSPs) were carried out in the granule cell stratum moleculare following stimulation of the perforant path in rat hippocampal slices. Under control conditions tetanic stimulation produced long-term potentiation (LTP) as measured by an increase in the initial slope of the pEPSPs that lasted for(More)
Although there is evidence that the thalamus plays a remarkable role in pain processing few in vivo studies on the thalamic neurochemical correlates of pain have been done. In the present experiments a combination of capillary zone electrophoresis with laser-induced fluorescence detection (CZE-LIF) and microdialysis in freely moving rats was used to measure(More)
The aim of this research was to find out the effects of ip morphine pretreatment in the extracellular content of the arginine, glutamate, aspartate and GABA levels in the anterior cingulate cortex in rats, during the formalin test (phase I). A combination of micro dialysis and Capillary Electrophoresis Zone and laser-induced fluorescence detection(More)
