Adenosine inhibits the NMDA receptor-mediated excitatory postsynaptic potential in the hippocampus

Brain Research, 1993
The 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.

Summation of excitatory postsynaptic potentials in hippocampal pyramidal cells

Journal of Neurophysiology, 1983
The summation of excitatory postsynaptic potentials (EPSPs) generated in separate parts of the dendritic tree of hippocampal pyramidal cells has been investigated using the in vitro slice preparation. Two separate inputs with known synaptic location were used.

Voltage dependence of excitatory postsynaptic potentials of rat neocortical neurons

Journal of Neurophysiology, 1991
1. The properties of excitatory postsynaptic potentials (EPSPs) of rat neocortical neurons were investigated with a fast single-electrode current-voltage clamp in vitro. Typically, apparently pure EPSPs were obtained by selection of electric stimuli of low intensity. 2.

Unitary Excitatory Postsynaptic Potentials in Clarke's Column Neurones

Nature, 1967
IT is generally believed that synaptic transmission is effected by a quantal release of transmitter substances, such as has been demonstrated for the neuromuscular junction1. The quantal nature of synaptic transmission in the central nervous system is more difficult to investigate, one reason being that many presynaptic fibres usually contribute to the

Excitatory Postsynaptic Potentials Trigger a Plateau Potential in Rat Subthalamic Neurons at Hyperpolarized States

Journal of Neurophysiology, 2001
The subthalamic nucleus (STN) directly innervates the output structures of the basal ganglia, playing a key role in basal ganglia function. It is therefore important to understand the regulatory mechanisms for the activity of STN neurons. In the present study, we aimed to investigate how the intrinsic membrane properties of STN neurons interact with ...

Pentobarbital: Selective Depression of Excitatory Postsynaptic Potentials [PDF]

Science, 1973
The effects of pentobarbital (Nembutal) on synaptic transmission and postsynaptic potentials were studied by the use of several invertebrate preparations. Pentobarbital selectively and reversibly depressed both excitatory postsynaptic potentials and sodium-dependent postsynaptic responses to putative excitatory transmitters without affecting either ...

Stretch-evoked excitatory postsynaptic potentials in motoneurons

Brain Research, 1971
Abstract The profile of excitatory postsynaptic potential (EPSP) produced on triceps surae motoneurons by 5 msec duration triangular wave stretch of de-efferented medial gastrocnemius (MG) and soleus (S) muscles was observed on anesthetized, spinalized cats.

Principal component analysis of minimal excitatory postsynaptic potentials

Journal of Neuroscience Methods, 1998
'Minimal' excitatory postsynaptic potentials (EPSPs) are often recorded from central neurones, specifically for quantal analysis. However the EPSPs may emerge from activation of several fibres or transmission sites so that formal quantal analysis may give false results.

Summation of excitatory postsynaptic potentials in electrically-coupled neurones

Neuroscience, 2009
Dendritic electrical coupling increases the number of effective synaptic inputs onto neurones by allowing the direct spread of synaptic potentials from one neurone to another. Here we studied the summation of excitatory postsynaptic potentials (EPSPs) produced locally and arriving from the coupled neurone (transjunctional) in pairs of electrically ...
