Postsynaptic potential summation and action potential initiation: function following form.

Advances in Physiology Education, 2004
The mechanisms and physiological significance of postsynaptic potential summation and action potential initiation are among the most difficult concepts for students to grasp. To help students understand these concepts, we emphasize that neurons have three distinct functional zones: 1 ) the ...

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.

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 ...

Self-modeling structure of evoked postsynaptic potentials [PDF]

Synapse, 2006
With the simplicity of the synaptic structure and physiology at neuromuscular junctions (NMJs) of crayfish and the given transmitter being released in quantal packets, a detailed assessment in the fundamental processes of chemical synaptic transmission is possible. Since the quantal event is the basic element of transmission, we consider an approach to
