Impact of the activation rate of the hyperpolarization-activated current on the neuronal membrane time constant and synaptic potential duration
Cesar C. Ceballos, Rodrigo F. O. Pena, Antonio C. Roque
The temporal dynamics of membrane voltage changes in neurons is controlled by ionic currents. These currents are characterized by two main properties: conductance and kinetics. The…
Modeling and characterizing stochastic neurons based on in vitro voltage-dependent spike probability functions
Vinicius Lima, Rodrigo F. O. Pena, Renan O. Shimoura +6
Neurons in the nervous system are submitted to distinct sources of noise, such as ionic-channel and synaptic noise, which introduces variability in their responses to repeated pres…
Boundary solution based on rescaling method: recoup the first and second-order statistics of neuron network dynamics
Cecilia Romaro, Antonio Carlos Roque, Jose Roberto Castilho Piqueira
There is a strong nexus between the network size and the computational resources available, which may impede a neuroscience study. In the meantime, rescaling the network while main…
Optimal interplay between synaptic strengths and network structure enhances activity fluctuations and information propagation in hierarchical modular networks
Rodrigo F. O. Pena, Vinicius Lima, Renan O. Shimoura +2
In network models of spiking neurons, the joint impact of network structure and synaptic parameters on activity propagation is still an open problem. Here we use an information-the…
Self-sustained activity of low firing rate in balanced networks
Fernando Borges, Paulo Protachevicz, Rodrigo Pena +10
Self-sustained activity in the brain is observed in the absence of external stimuli and contributes to signal propagation, neural coding, and dynamic stability. It also plays an im…
Asymmetrical voltage response in resonant neurons shaped by nonlinearities
Rodrigo F. O. Pena, Vinicius Lima, Renan O. Shimoura +3
The conventional impedance profile of a neuron can identify the presence of resonance and other properties of the neuronal response to oscillatory inputs, such as nonlinear respons…
