Petri Net Description of Biological Neural Circuits for Fast Hardware Prototyping
Carlo daCunha, Rodrigo Pena, Marcos Turqueti
Current approaches to simulating biological neural circuits, whether on general-purpose hardware or dedicated neuromorphic platforms, remain constrained by fixed-timestep numerical…
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…
Building a model of the brain: from detailed connectivity maps to network organization
Renan Oliveira Shimoura, Rodrigo F. O. Pena, Vinicius Lima +3
The field of computational modeling of the brain is advancing so rapidly that now it is possible to model large scale networks representing different brain regions with a high leve…
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…
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…
