Detection of Spontaneous Postsynaptic Potentials

Computers and Biomedical Research, 1995
The amplitude and time course of postsynaptic potentials (PSPs) recorded by intracellular techniques contain information that allow different synaptic events to be detected. In the present paper an algorithm to detect spontaneous PSPs is described. The algorithm is based on computation of approximations of first and second derivatives of the signals ...

Mechanisms of slow postsynaptic potentials

Nature, 1981
Classical views of synaptic transmission have to be modified to take account of slow postsynaptic potentials (p.s.ps), which are often mediated by novel ionic and molecular mechanisms and which are sometimes evoked by neuropeptides. Understanding slow p.s.ps will provide insights into the mechanisms of biological signal transduction and long-term ...

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 ...

Inhibitory Postsynaptic Potentials in Grasshopper Muscle

Science, 1964
Hyperpolarizing inhibitory postsynaptic potentials have been discovered in fibers of the "jumping" muscle of the grasshopper. These potentials attenuate the depolarizing excitatory postsynaptic responses. They are enhanced during depolarization of the muscle fiber with applied current and are diminished and then reversed during hyperpolarization.

Ion channels and postsynaptic potentials

Biophysical Chemistry, 1988
Neurotransmitters open transmembrane ion channels in target membranes. At the motor endplate, the open time of channels activated by acetylcholine determines the time course of the endplate current. Endplate channels are selective for cations and their conductance and open times are influenced by the nature of the permeating cation.

Quantum analysis of postsynaptic potentials

Neurophysiology, 1979
Basic formulations of the quantum theory for synaptic transmission are listed. Methods for determining the mean quantum content, quantum value and binomial parameters describing the amplitude distributions of the unitary and "minimal" postsynaptic potentials are discussed.

Prolongation of hippocampal inhibitory postsynaptic potentials by barbiturates

Nature, 1975
IT is well documented that barbiturates dramatically prolong presynaptic inhibition1–4. Their effect on postsynaptic inhibition is less clear, although the available evidence suggests that a similar enhancement may occur at some sites5–7. Since the inhibitory postsynaptic potentials (i.p.s.p.s) in hippocampal neurones are unusually large and the ...
