Sensory processing is associated with gamma frequency oscillations (30–80 Hz) in sensory cortices. This raises the question whether gamma oscillations can be directly involved in the representation of time-varying stimuli, including stimuli whose time scale is longer than a gamma cycle. We are interested in the ability of the system to reliably distinguish different stimuli while being robust to stimulus variations such as uniform time-warp. We address this issue with a dynamical model of…

Multi-Scale Entrainment of Coupled Neuronal Oscillations in Primary Auditory Cortex
The authors' data indicate that the suppressive effects were due to low excitability phase delta oscillatory entrainment and the phase amplitude coupling of delta and gamma oscillations, indicative of the hemispheric lateralization of auditory function.
Flexible reset and entrainment of delta oscillations in primate primary auditory cortex: modeling and experiment
Fundamental mechanisms by which neurons of the auditory cortex can synchronize their activity to rhythmic external stimuli are suggested, which are thought to underlie the processing of naturalistic auditory inputs like speech or music.
Speech encoding by coupled cortical theta and gamma oscillations
It is demonstrated that cortical oscillations can be a key instrument of speech de-multiplexing, parsing, and encoding and can flexibly track the syllabic rhythm and temporally organize the phoneme-level response of gamma neurons into a code that enables syllable identification.
Oscillations can reconcile slowly changing stimuli with short neuronal integration and STDP timescales
This review argues that thanks to oscillations, even slowly changing stimuli can be encoded in precise relative spike times, decodable by downstream “coincidence detector” neurons in a feedforward manner, and the required connectivity to do so can spontaneously emerge with spike timing-dependent plasticity (STDP), in an unsupervised manner.
Emergence of oscillations via spike timing dependent plasticity
This work focuses on spike timing dependent plasticity (STDP) to investigate whether oscillatory activity can emerge in a neuronal network via an unsupervised learning process of STDP dynamics, and if so, what features of the STDP learning rule govern and stabilize the resultant oscillatoryActivity.
Robust Rhythmogenesis in the Gamma Band via Spike Timing Dependent Plasticity
This work examines STDP dynamics in the framework of a network of excitatory and inhibitory neuronal populations that has been suggested to underlie the generation of gamma, and proposes a novel mechanism that can ensure the robustness of self-developing processes, in general and for rhythmogenesis in particular.
Encoding speech through brain rhythms
A neural microcircuit model of nested oscillations for early auditory processing, involving a fast Gamma rhythm coupled to a slow Theta rhythm, found that Bottom-up information is dominated by Gamma oscillations, while Top-Down flow is conveyed through Theta oscillations.
Taxonomy of neural oscillation events in primate auditory cortex
This study demonstrates that rhythmic, multi-cycle oscillation events dominate auditory cortical dynamics in human and non-human primate auditory system.
Analytical Insights on Theta-Gamma Coupled Neural Oscillators
Analytical and semianalytical methods are used to derive characteristic spiking times for a quadratic integrate-and-fire neuron, spiking in the gamma (30–100 Hz) range, coupled to a delta/theta frequency neural oscillator, and provide an estimation of the total number of spikes per theta cycle both for excitable and oscillator regimes.
Multiplexing rhythmic information by spike timing dependent plasticity
Findings imply that STDP can support the multiplexing of rhythmic information, and demonstrate how functionality can be retained in the face of continuous remodeling of all the synaptic weights.


Temporal Coding of Time-Varying Stimuli
It is shown that information content of the temporal response scales linearly with the overall time of the response, even in the presence of temporal noise correlations, and that finite temporal resolution is sufficient for obtaining most of the information from the cell's response.

Many stimuli have meaning only as patterns over time. Most auditory and many visual stimuli are of this nature and can be described as multidimensional, time-dependent vectors. A simple neuron can
Olfactory Bulb Gamma Oscillations Are Enhanced with Task Demands
Fast oscillations in neural assemblies have been proposed as a mechanism to facilitate stimulus representation in a variety of sensory systems across animal species. In the olfactory system,
Oscillatory γ-Band (30–70 Hz) Activity Induced by a Visual Search Task in Humans
It is suggested that this γ-band energy increase reflects both bottom-up (binding of elementary features) and top-down (search for the hidden dog) activation of the same neural assembly coding for the Dalmatian.
Phase Synchrony among Neuronal Oscillations in the Human Cortex
It is demonstrated, using magnetoencephalography, that robust cross-frequency phase synchrony is present in the human cortex among oscillations with frequencies from 3 to 80 Hz and that it is modulated by cognitive task demands.
Polychronization: Computation with Spikes
We present a minimal spiking network that can polychronize, that is, exhibit reproducible time-locked but not synchronous firing patterns with millisecond precision, as in synfire braids. The network

It is suggested that this gamma-band energy increase reflects both bottom-up (binding of elementary features) and top-down (search for the hidden dog) activation of the same neural assembly coding for the Dalmatian.
An oscillatory hierarchy controlling neuronal excitability and stimulus processing in the auditory cortex.
It is proposed that the hierarchical organization of ambient oscillatory activity allows auditory cortex to structure its temporal activity pattern so as to optimize the processing of rhythmic inputs.

The results demonstrate that local neuronal populations in the visual cortex engage in stimulus-specific synchronous oscillations resulting from an intracortical mechanism, and may provide a general mechanism by which activity patterns in spatially separate regions of the cortex are temporally coordinated.
The Consequences of Response Nonlinearities for Interpretation of Spectrotemporal Receptive Fields
Analytically and in simulations, it is demonstrated that, even when uncorrelated stimuli are used, interactions between simple neuronal nonlinearities and higher-order structure in the stimulus can produce STRFs that show contributions from time–frequency combinations to which the neuron is actually insensitive.
