Simultaneous expression of excitatory postsynaptic potential/spike potentiation and excitatory postsynaptic potential/spike depression in the hippocampus

Neuroscience, 1995
Tetanic stimulation of afferents in the stratum radiatum of the CA1 area of the rat hippocampus results in long-term potentiation of excitatory synaptic responses in pyramidal cells. Previous studies have reported a greater increase in the population spike amplitude following the induction of long-term potentiation than could be accounted for by the ...

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.

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 ...

A characterization of excitatory postsynaptic potentials in the avian nucleus magnocellularis.

Journal of Neurophysiology, 1994
1. The activation of current-clamped neurons in the chick nucleus magnocellularis (nMAG) by eighth nerve stimulation has been studied in a brain slice preparation using patch electrodes. Single presynaptic stimuli produced rapidly rising, suprathreshold, excitatory postsynaptic potentials (EPSPs) with a synaptic delay of approximately 0.4 ms ...

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.

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

Pentobarbital: Selective Depression of Excitatory Postsynaptic Potentials

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 ...
