Corticothalamic Pathways From Layer 5: Emerging Roles in Computation and Pathology

open access: yesFrontiers in Neural Circuits, 2021
Large portions of the thalamus receive strong driving input from cortical layer 5 (L5) neurons but the role of this important pathway in cortical and thalamic computations is not well understood.

Mechanisms leading to bursting oscillations in the system of predator–prey communities coupled by migrations [PDF]

open access: yesИзвестия высших учебных заведений: Прикладная нелинейная динамика, 2023
The purpose is to study the periodic regimes of the dynamics for two non-identical predator–prey communities coupled by migrations, associated with the partial synchronization of fluctuations in the abundance of communities.

Suppression of bursting

open access: yesAutomatica, 1997
It is well known that heteroclinic cycles can occur stably in the context of equivariant systems. For initial values near the cycle, one observes long time behaviour near an equilibrium and sudden bursts describing the travel along a heteroclinic connection. The goal of the paper is to construct feedback strategies to avoid bursting.

Mechanisms for multiple activity modes of VTA dopamine neurons

open access: yesFrontiers in Computational Neuroscience, 2015
Midbrain ventral segmental area (VTA) dopaminergic neurons send numerous projections to cortical and sub-cortical areas, and diffusely release dopamine (DA) to their targets.

Bursting Oscillation and Its Mechanism of a Generalized Duffing–Van der Pol System with Periodic Excitation

open access: yesComplexity, 2021
The complex bursting oscillation and bifurcation mechanisms in coupling systems of different scales have been a hot spot domestically and overseas.

Molecular Mechanisms of REM Sleep

open access: yesFrontiers in Neuroscience, 2020
Rapid-eye movement (REM) sleep is a paradoxical sleep state characterized by brain activity similar to wakefulness, rapid-eye-movement, and lack of muscle tone.

Bursting dynamics in a spiking neuron with a memristive voltage-gated channel

open access: yesNeuromorphic Computing and Engineering, 2023
We introduce a voltage-gated conductance model for an artificial neuron that exhibits tonic, fast, and two types of intrinsic burst spiking. The spike generation is achieved with a single voltage-gated channel that exploits the conductance commutation ...

Fast radio bursts [PDF]

open access: yesThe Astronomy and Astrophysics Review, 2019
AbstractThe discovery of radio pulsars over a half century ago was a seminal moment in astronomy. It demonstrated the existence of neutron stars, gave a powerful observational tool to study them, and has allowed us to probe strong gravity, dense matter, and ...

Understanding the Generation of Network Bursts by Adaptive Oscillatory Neurons

open access: yesFrontiers in Neuroscience, 2018
Experimental and numerical studies have revealed that isolated populations of oscillatory neurons can spontaneously synchronize and generate periodic bursts involving the whole network.

Noise-tuned bursting in a Hedgehog burster

open access: yesFrontiers in Computational Neuroscience, 2022
Noise can shape the firing behaviors of neurons. Here, we show that noise acting on the fast variable of the Hedgehog burster can tune the spike counts of bursts via the self-induced stochastic resonance (SISR) phenomenon.
