Age-Dependent Generation of Epileptiform Activity in the 4-Aminopyridine Model with Slices of the Rat Entorhinal Cortex
Children are more likely to develop epileptic seizures (ictal discharges lasting tens of seconds) than adults. A higher predisposition of the juvenile brain to the generation of epileptiform activity is though...

AMPAR-mediated Interictal Discharges in Neurons of Entorhinal Cortex: Experiment and Model
The mechanisms of interictal discharges (IID) were studied under the conditions of the 4-aminopyridine model of spontaneous epileptiform activity in surviving rat brain slice preparations. Addition of the agen...

Effect of Persistent Sodium Current on Neuronal Activity
In epilepsy, the number of persistent sodium (NaP) channels increases. To study their effects on neuronal excitability we applied dynamic-clamp (DC). We have revealed that NaP current decreases rheobase, promo...

The domain of neuronal firing on a plane of input current and conductance
The activation of neurotransmitter receptors increases the current flow and membrane conductance and thus controls the firing rate of a neuron. In the present work, we justified the two-dimensional representat...

Experimental and Modeling Studies of Orientational Sensitivity of Neurons in the Lateral Geniculate Nucleus
Experimental studies have shown that the orientation selectivity of visual stimuli is characteristic not only of cortical, but also of subcortical neurons in the dorsal nucleus of the lateral geniculate body i...

A simple Markov model of sodium channels with a dynamic threshold
Characteristics of action potential generation are important to understanding brain functioning and, thus, must be understood and modeled. It is still an open question what model can describe concurrently the ...

Quantum entanglement in a two-electron quantum dot in magnetic field
The properties of quantum entanglement of the ground state in an exactly solvable model of a two-electron QD have been investigated. It is shown that the degree of entanglement increases with enhancement of in...

Orientation hypercolumns of the visual cortex: Ring model
A hypercolumn of the visual cortex is a functional unit formed of neighboring columns whose neurons respond to a stimulus of particular orientation. The function of the hypercolumn is to amplify the orientatio...

Firing-rate model of a population of adaptive neurons
A firing rate (FR) model for a population of adaptive leaky integrate-and-fire neurons has been proposed. Unlike known FR models, it describes more precisely the unsteady firing regimes and takes into account ...

Modified firing-rate model reproduces synchronization of a neuronal population receiving complex input
Synchronization plays important role in generation of brain activity patterns. Experimental data show that neurons demonstrate more reproducible activity for noise-like input than for constant current injectio...

Stokes-anti-Stokes entanglement in stimulated Raman scattering
A cavity model of Raman scattering from phonons by an undepleted laser field is considered. The fields in the interaction are coupled to the boson reservoir that produces the dam** mechanism in the model. An...

Estimation of synaptic currents by recordings from extracellular electrodes
A method for estimating the synaptic current distribution is described, which is based on solving the inverse problem for a system of homogeneously distributed parallel cylinders as a model of dendrites of the...

Entanglement in a two-boson coupled system
A model for two nondegenerate cavity fields coupled through a reservoir is considered. Such a model can be employed for the study of Raman scattering in which the Stokes and anti-Stokes fields indirectly inter...

Phase representation of quantum-optical systems via the nonnegative quantum distribution function
We propose a new method for describing phase distributions of nonclassical states in optical systems based on the nonnegative quantum distribution function. A comparison of the proposed method with other known...

Entanglement fidelity of coherent-state teleportation with asymmetric quantum channel
A strategy for teleporting coherent states with the entanglement fidelity is considered in the general case of an asymmetric teleportation scheme. It is shown that the nonbalanced homodyne detection with the s...
