Spontaneous synchronization of Purkinje cell pairs in the cerebellar cortex is implicitly predicted by many theories of cerebellar function (e.g.the beam theory of Eccles [19]). We show that monosynaptic parallel fiber excitation is not able to synchronize model Purkinje cell pairs, unless...

Common measures for the tuning of cells that are used in the neuroscience literature break down even in the case of moderately noisy neurons. For this reason, a considerable proportion of recorded neuronal data remains unconsidered. One reason for the unreliability of tuning measures is that...

We investigated the effect of the phase relationship between two frequency components of a periodic stimulus on cortical neurons and on simulated Integrate- and-Fire (IF) model neurons. It is well established that entrainment to a resonant frequency in a fluctuating stimulus can induce reliable...

To investigate the cortical mechanisms underlying the determination of apparent tilt, including the tilt illusion, we developed and examined a V1 network model consisting of cortical neurons and phase-coupled oscillators for neural grouping. Grouping local orientations based on V1 colinear...

Attentional systems must be able to identify non-salient sensory input so as to allocate appropriate neural resources. Auditory stimuli delivered high repetition rates may represent a background barrage of noncritical information. Scalp electrode recordings were obtained from human subjects in...

We propose a versatile signal processing and analysis framework for bioelectrical data, and in particular for neural recordings and EEG. Within this framework the signal is decomposed into subbands using fast wavelet transform algorithms, executed in real-time on a current DSP hardware platform....

The paper investigates the role of backward propagating potential waves in the regulation of the firing rate input ‐ output transformation function of neurons. The analysis is performed using a simple one dimensional neuron model that allows backward propagating waves that appear in...

The well-known Kullback-Leibler divergence of a random field from its factorization quantifies spatial interdependencies of the corresponding stochastic elements. In the present work, we introduce a generalized measure for stochastic interaction that captures also temporal interdependencies....

Multichannel EEG recordings from trained animals with high-density epipial arrays of electrodes fixed on cortical sensory areas reveal spatiotemporal patterns. These patterns have the form of temporal modulations of the phase (PM) and amplitude (AM) of spatially coherent carrier waves with...

The correlated activity of neurons is being regarded as candidate mechanism for binding the responses of different feature selective cells. Binding, however, is rarely unique, especially at levels beyond feature detection. In this article the dynamical properties of a network of coupled...
