Excitatory postsynaptic potentials in rat neocortical neurons in vitro. III. Effects of a quinoxalinedione non-NMDA receptor antagonist [PDF]
Journal of Neurophysiology, 1990 1. Intracellular microelectrodes were used to obtain recordings from neurons in layer II/III of rat frontal cortex. A bipolar electrode positioned in layer IV of the neocortex was used to evoke postsynaptic potentials.

Active summation of excitatory postsynaptic potentials in hippocampal CA3 pyramidal neurons [PDF]
Proceedings of the National Academy of Sciences, 1998 The manner in which the thousands of synaptic inputs received by a pyramidal neuron are summed is critical both to our understanding of the computations that may be performed by single neurons and of the codes used by neurons to transmit information. Recent work on pyramidal cell dendrites has shown that subthreshold synaptic inputs are modulated by ...

Recurrent excitatory postsynaptic potentials induced by synchronized fast cortical oscillations [PDF]
Proceedings of the National Academy of Sciences, 1997 Gamma frequency (about 20–70 Hz) oscillations occur during novel sensory stimulation, with tight synchrony over distances of at least 7 mm. Synchronization in the visual system has been proposed to reflect coactivation of different parts of the visual field by a single spatially extended object.

Calcium dynamics in single spines during coincident pre- and postsynaptic activity depend on relative timing of back-propagating action potentials and subthreshold excitatory postsynaptic potentials [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 1998 We compared the transient increase of Ca2+ in single spines on basal dendrites of rat neocortical layer 5 pyramidal neurons evoked by subthreshold excitatory postsynaptic potentials (EPSPs) and back-propagating action potentials (APs) by using calcium ...

Data compression of excitatory postsynaptic potentials
Electronics Letters, 2015 Reducing the size of biosignal data is important because a huge amount of data is made by various experiments. In this reported work excitatory postsynaptic potentials (EPSPs) which are one of the biosignal types are efficiently compressed. To the best of authors’ knowledge, EPSPs compression has not been studied yet. The EPSP signal has a feature that

Purinergic fast excitatory postsynaptic potentials in myenteric neurons of guinea pig: Distribution and pharmacology [PDF]
Gastroenterology, 1997 BACKGROUND & AIMS Adenosine triphosphate (ATP) acting at P2 receptors mediates some fast excitatory postsynaptic potentials (fEPSPs) in myenteric neurons of guinea pig ileum. The present studies investigate the distribution of purinergic fEPSPs along the

The Journal of Physiology, 1990 1. The effects of acetylcholine (ACh) on excitatory postsynaptic potentials (EPSPs) evoked by stimulating Schaffer‐commissural afferents and on ionophoretically applied L‐glutamate ligands, were investigated in CA1 neurones of hippocampal slices using current‐ and voltage‐clamp techniques. 2.

Dopamine enhances both electrotonic coupling and chemical excitatory postsynaptic potentials at mixed synapses. [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 1992 The transmitter dopamine reduces electrotonic coupling between retinal horizontal cells and increases their sensitivity to glutamate. Since in other systems single afferents establish mixed electrotonic and chemical excitatory synapses with their targets,

Journal of Neurophysiology, 2011 Sensory afferent transmission and associated spinal reflexes are normally inhibited by serotonin (5-HT) derived from the brain stem. Spinal cord injury (SCI) that eliminates this 5-HT innervation leads to a disinhibition of sensory transmission and a ...
