Clinical EEG and Neuroscience, 2008
Midline spikes are characterized by spike foci recorded at Cz, Fz, or Pz with amplitude ranging from 20 to 350 microvolts. Out of 7,929 EEGs performed at the Neurodiagnostics Laboratory, Kaiser Permanente Medical Center, Anaheim, California, between 1996 and 2006, 17 EEGs (0.21%) were identified as having interictal midline spikes with or without other

IEEE Transactions on Neural Networks, 2006
A more plausible biological version of the traditional perceptron is presented here with a learning rule which enables training of the neuron on nonlinear tasks. Three different models are introduced with varying inhibitory and excitatory synaptic connections.

Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1975
Abstract Among the signs of activity in excitable membranes, the action current (electrical spike) has been extensively studied. Recently, a new approach with optical methods has been rewarding. In nerves, a transient, rapid change of light scattering, birefringence and induced fluorescence can be observed during the passage of the ...

Clinical EEG and Neuroscience, 2009
Digital EEG analysis provides significantly more information to the clinical electroencephalographer (EEGer) for scalp as well as for intracranial monitoring than is currently being routinely utilized. When modern data analysis software is used, interictal spikes contain considerably more information than had previously been ascribed to them.

The innate immune system is the first line of defence against invading microorganisms. Specialized immune cells, primarily myeloid cells, sense conserved pathogen-associated molecular patterns (PAMPs) through pattern recognition receptors (PRRs) to coordinate an immune response.

Simple Spikes and Complex Spikes
2016Cerebellar Purkinje neurons communicate with downstream circuit elements by generating two distinct types of electrical activity. Purkinje neurons fire conventional action potentials, termed simple spikes, and they also intermittently fire a highly stereotyped burst of decrementing spikes, called a complex spike.

Cholinergic modulation of spike timing and spike rate
Neurocomputing, 1999Little is known about the constraints that neuromodulation places upon neural coding. We investigated the relationship between cholinergic modulation of spike timing and rate in a compartment model of a neocortical neuron. Our results suggest that cholinergic modulation of spike timing is directly related to the modulation of spike rate via the ...

Epilepsia, 1959
SUMMARY AND CONCLUSIONS1. Some of the properties of epileptic neurons are discussed. It would appear that the major abnormalities reside in the dendrites. The epileptic spike is one consequence of this dendritic abnormality.2. There is a variable relationship between dendritic and cell body discharge.3.

Approximation of Spike-trains by Digital Spiking Neuron
2007 International Joint Conference on Neural Networks, 2007A digital spiking neuron (DSN) consists of shift registers and can generate spike-trains with various patterns of inter-spike intervals. In this paper we present a learning algorithm for the DSN in order to approximate given spike-trains. We study a case where a student DSN accepts a spike-train from a teacher DSN.
