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…
Granger causality in the frequency domain: derivation and applications
Vinicius Lima, Fernanda Jaiara Dellajustina, Renan O. Shimoura +4
Physicists are starting to work in areas where noisy signal analysis is required. In these fields, such as Economics, Neuroscience, and Physics, the notion of causality should be i…
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…
Interplay of activation kinetics and the derivative conductance determines resonance properties of neurons
Rodrigo F. O. Pena, Cesar C. Ceballos, Vinicius Lima +1
In a neuron with hyperpolarization activated current (), the correct input frequency leads to an enhancement of the output response. This behavior is known as resonance and is…
