Intracellular recording techniques were used to study a fast hyperpolarizing potential following the fast excitatory postsynaptic potential evoked by an orthodromic nerve stimulation in cat bladder parasympathetic ganglion cells. In the 61 ganglion cells examined, two types of responses were recorded on stimulating the preganglionic nerve; one had only

Adenosine inhibits the NMDA receptor-mediated excitatory postsynaptic potential in the hippocampus
Brain Research, 1993The effect of the stable adenosine analogue 2-chloroadenosine (CADO) on the component of the field excitatory postsynaptic potential (fepsp) mediated by the N-methyl-D-aspartate (NMDA) type of glutamate receptor was studied in the hippocampal CA1 area of the rat.

Anoxic depression of excitatory and inhibitory postsynaptic potentials in rat neocortical slices
Journal of Neurophysiology, 19931. The effects of brief anoxia (4-6 min replacement of O2 by N2) on synaptic potentials evoked from layer IV and/or the white matter were studied in pyramidal neurons of layers II-III from rat neocortical slices. 2. The early and late components of excitatory postsynaptic potentials (EPSPs) showed differential sensitivity to anoxia: within 2 min the ...

Application of 5-hydroxytryptamine (5-HT) to the lamprey spinal cord in vitro reversibly depressed the chemical component of excitatory post-synaptic potentials recorded intracellularly in motoneurons and evoked by stimulation of single reticulospinal Müller cells. The depression could be produced either by local application of small volumes of 10 mM 5-

The spike peak and after-hyperpolarization of the action potential of bullfrog sympathetic ganglion cells were depressed during the late slow excitatory postsynaptic potential (EPSP). These changes in the action potential were mimicked by luteinizing hormone-releasing hormone (LH-RH), a neurotransmitter candidate for the late slow EPSP. LH-RH (5 microM)

In the CA1 area of the hippocampus, low frequency and tetanic conditioning stimuli are known to trigger long-term depression and potentiation of synaptic responses respectively and to produce irreversible excitatory postsynaptic potential/spike potentiation, i.e. an increase of the probability of discharge of the neurons.

Development of excitatory and inhibitory postsynaptic potentials in the rat neocortex.
Perspectives on developmental neurobiology, 1995The postnatal development of synaptic potentials in the rat neocortex is characterized by the sequential appearance of functional excitatory and inhibitory synapses. Morphological and electrophysiological studies provided evidence that at early stages of development, pyramidal cells are extensively coupled to each other, presumably via gap junctions ...

Excitatory Postsynaptic Potentials of Hippocampal Neurones and Their Low-Frequency Depression
1993The results obtained with recordings of aggregate (Chap. 1) and minimal FPs (Chap. 3) were considered as a support of the hypothesis suggesting that the basic LTP mechanism is a persistent increase in the efficacy of excitatory synapses. Nevertheless, it was necessary to test this hypothesis more directly with intracellular recordings, including ...
