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. ...
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 ...
Excitatory synaptic transmission is associated with changes in both extracellular and intracellular pH. Using mouse cortical neurons in primary cultures, we studied the sensitivity of glutamate-evoked release of 3H-arachidonic acid (3H-AA) to changes in ex ...
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 ...
We examined the effect of elevating intracellular calcium ([Ca2+]i) on responses to iontophoretically applied N-methyl-D-aspartate (NMDA), and quisqualate in CA1 neurons of the hippocampal slice. Topical application of calcimycin (A23187), a calcium ionoph ...
The therapeutic action of lithium in affective disorders is still unclear. One effect of lithium is to deplete membrane inositol and consequently to exhaust the phosphoinositide (PI) pathway. Under chronic lithium treatment, rats showed persistent performa ...
Acting at postsynaptic alpha 1- and beta 1-receptors, norepinephrine (NE) exerts a complex action in rat hippocampus. It is currently believed that beta 1-receptor activation enhances excitability of recorded neurons, whereas alpha 1 activation suppresses ...
Dual voltage recordings were made from pairs of adjacent, synaptically connected thick tufted layer 5 pyramidal neurones in brain slices of young rat (14-16 days) somatosensory cortex to examine the physiological properties of unitary EPSPs. Pre- and po ...
The cellular mechanism by which acetylcholine (ACh) potentiates neuronal responses to N-methyl-D-aspartate (NMDA) was investigated in CA1 neurones of hippocampal slices using current- and voltage-clamp techniques. 2. Loading cells with 5'-guanylylimidod ...
