Functional importance of noise in neuronal information processing
Daqing Guo, Matjaz Perc, Tiejun Liu +1
Noise is an inherent part of neuronal dynamics, and thus of the brain. It can be observed in neuronal activity at different spatiotemporal scales, including in neuronal membrane po…
Robustness of functional networks at criticality against structural defects
Abdorreza Goodarzinick, Mohammad D. Niry, Alireza Valizadeh +1
The robustness of dynamical properties of neuronal networks against structural damages is a central problem in computational and experimental neuroscience. Research has shown that…
Frequency-difference-dependent stochastic resonance in neural systems
Daqing Guo, Matjaz Perc, Yangsong Zhang +2
Biological neurons receive multiple noisy oscillatory signals, and their dynamical response to the superposition of these signals is of fundamental importance for information proce…
Synchronization of oscillators through time-shifted common inputs
Ehsan Bolhasani, Yousef Azizi, Alireza Valizadeh +1
Shared upstream dynamical processes are frequently the source of common inputs in various physical and biological systems. However, due to finite signal transmission speeds and dif…
Regulation of Irregular Neuronal Firing by Autaptic Transmission
Daqing Guo, Shengdun Wu, Mingming Chen +7
The importance of self-feedback autaptic transmission in modulating spike-time irregularity is still poorly understood. By using a biophysical model that incorporates autaptic coup…
Firing regulation of fast-spiking interneurons by autaptic inhibition
Daqing Guo, Mingming Chen, Matjaz Perc +6
Fast-spiking (FS) interneurons in the brain are self-innervated by powerful inhibitory GABAergic autaptic connections. By computational modelling, we investigate how autaptic inhib…
