Death pathways restricted to specific neuronal classes could potentially allow for precise control of developmental neuronal death and also underlie the selectivity of neuronal loss in neurodegenerative disease. We show that Fas-triggered death of normal e ...
The effects of inhibitors of the glial Na+/glutamate co-transporter on the intracellular Na+ concentration (Na+) were investigated in mouse cortical astrocytes. Na+ was monitored by fluorescence microscopy on single astrocytes using the Na+-sensi ...
In this study we examined the passive biocompatibility of a three-dimensional microelectrode array (MEA), designed to be coupled to organotypic brain slice cultures for multisite recording of electrophysiological signals. Hippocampal (and corticostriatal) ...
The mode of Na+ entry and the dynamics of intracellular Na+ concentration ([Na+]i) changes consecutive to the application of the neurotransmitter glutamate were investigated in mouse cortical astrocytes in primary culture by video fluorescence microscopy. ...
Although correct cycling of neuronal membrane proteins is essential for neurite outgrowth and synaptic plasticity, neuron-specific proteins of the implicated endosomes have not been characterized. Here we show that a previously cloned, developmentally regu ...
BACKGROUND: Deep hypothermia has been associated with an increased incidence of postoperative neurologic dysfunction after cardiac surgery in children. Recent studies suggest an excitotoxic mechanism involving overstimulation of glutamate receptors. Extrac ...
We quantified the effect of the excitatory amino acids kainate and glutamate on the uptake of cobalt in primary rat cerebellar granule neurons, by using inductively coupled plasma-atomic emission spectroscopy (ICP-AES). We quantitatively demonstrated that ...
In view of the neurotrophic effect of vasoactive intestinal peptide (VIP), the regulation of brain-derived neurotrophic factor (BDNF) expression by VIP and the related peptide pituitary adenylate cyclase-activating polypeptide (PACAP) was analysed by North ...
Conventional intracellular recordings were used to monitor postsynaptic potentials of basolateral amygdala neurones (BLA) in brain slices comprising the BLA, the entorhinal cortex (EC) and the hippocampus, in which the EC-BLA connections were preserved. St ...

Long-term memory formation for a weak passive avoidance task in day-old chicks is facilitated by corticosterone administration. Since (i) glutamatergic systems, through different receptor types, play a key role in learning and memory processes, and (ii) gl ...
