Synaptic Noise and Physiological Coupling Generate High-Frequency Oscillations in a Hippocampal Computational Model

William C. Stacey, Maciej T. Lazarewicz, Brian Litt
2009 Journal of Neurophysiology  
The combined effects of network coupling and synaptic noise produced coherent, periodic oscillations within the network, an example of CR.  ...  Addition of basket cell interneurons produced two novel SR effects: 1) improved signal detection at low noise levels and 2) formation of coherent oscillations at high noise that were entrained to harmonics  ...  The network oscillations result from coupling of individual oscillating neurons. The model was first tested with a single neuron to compare it with the network response.  ...

Interacting biological and electronic neurons generate realistic oscillatory rhythms

Attila Szücs, Pablo Varona, Alexander R. Volkovskii, Henry D. I. Abarbanel, Mikhail I. Rabinovich, Allen I. Selverston
2000 NeuroReport  
We found that the periodic bursting oscillation of this mixed assembly depends on the strength and sign of the electrical coupling.  ...  In contrast, individual CPG neurons isolated from the remainder of the network can generate irregular ®ring patterns.  ...  An analog network of coupled subthreshold oscillators was connected to olivary neurons in Yarom's work [19] and the mechanisms of synchronized neural oscillations were investigated.  ...

Coupling Functions in Neuroscience [article]

Tomislav Stankovski
2020 arXiv   pre-print
Coupling functions are discussed in connection to two different levels of brain interactions - that of neuron interactions and brainwave cross-frequency interactions.  ...  The interactions play one of the central roles in the brain mediating various processes and functions.  ...  In this way, therefore, the brain connectivity is crucial to understand how neurons and neural networks process information.  ...

Oscillation-Induced Signal Transmission and Gating in Neural Circuits

Sven Jahnke, Raoul-Martin Memmesheimer, Marc Timme, Christoph Kayser
2014 PLoS Computational Biology  
We find that for standard, additive couplings and a net excitatory effect of oscillations, robust propagation of synchrony is enabled in less prominent feed-forward structures than in systems without oscillations  ...  In the presence of non-additive coupling (as mediated by fast dendritic spikes), even balanced oscillatory inputs may enable robust propagation.  ...  As we show below this shift clearly influences propagation of synchrony in additively coupled networks, but has only a weak effect in non-additively coupled systems.  ...

Resonance-enhanced signal detection and transduction in the Hodgkin-Huxley neuronal systems

2001 Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics  
The ability of signal detection and transduction of the Hodgkin-Huxley neuronal systems, associated with rhythmic oscillations in the presence of external modulations, is studied.  ...  Both inhibitory and excitatory modulations, regarded as the total effects of the environment in which the neurons are located, are able to modulate the frequencies of the rhythmic oscillations of the neurons  ...  It is known that there are thousands of neurons connected to each other in the network. Thus, the average synaptic input to a neuron may vary slowly with time.  ...
