Plastic neural network with transmission delays promotes equivalence between function and structure
P. R. Protachevicz, F. S. Borges, A. M. Batista +4
The brain is formed by cortical regions that are associated with different cognitive functions. Neurons within the same region are more likely to connect than neurons in distinct r…
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…
Influence of inhibitory synapses on the criticality of excitable neuronal networks
F S Borges, P R Protachevicz, V Santos +7
In this work, we study the dynamic range of a neuronal network of excitable neurons with excitatory and inhibitory synapses. We obtain an analytical expression for the critical poi…
Noise induces continuous and noncontinuous transitions in neuronal interspike intervals range
P R Protachevicz, M S Santos, E G Seifert +11
Noise appears in the brain due to various sources, such as ionic channel fluctuations and synaptic events. They affect the activities of the brain and influence neuron action poten…
Short-term and spike-timing-dependent plasticities facilitate the formation of modular neural networks
Ewandson L. Lameu, Fernando S. Borges, Kelly C. Iarosz +4
The brain has the phenomenal ability to reorganize itself by forming new connections among neurons and by pruning others. The so-called neural or brain plasticity facilitates the m…
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…
Alterations in brain connectivity due to plasticity and synaptic delay
E. L. Lameu, E. E. N. Macau, F. S. Borges +6
Brain plasticity refers to brain's ability to change neuronal connections, as a result of environmental stimuli, new experiences, or damage. In this work, we study the effects of t…
Inference of topology and the nature of synapses, and the flow of information in neuronal networks
F. S. Borges, E. L. Lameu, K. C. Iarosz +6
The characterisation of neuronal connectivity is one of the most important matters in neuroscience. In this work, we show that a recently proposed informational quantity, the causa…
Synaptic Plasticity and Spike Synchronisation in Neuronal Networks
Rafael R. Borges, Fernando S. Borges, Ewandson L. Lameu +8
Brain plasticity, also known as neuroplasticity, is a fundamental mechanism of neuronal adaptation in response to changes in the environment or due to brain injury. In this review,…
Synchronised firing patterns in a random network of adaptive exponential integrate-and-fire
Fernando da Silva Borges, Paulo Ricardo Protachevicz, Ewandson Luiz Lameu +5
We have studied neuronal synchronisation in a random network of adaptive exponential integrate-and-fire neurons. We study how spiking or bursting synchronous behaviour appears as a…
Suppression of neuronal phase synchronisation in cat cerebral cortex
Ewandson L. Lameu, Fernando S. Borges, Rafael R. Borges +5
We have studied effects of perturbations on the cat cerebral cortex. According to the literature, this cortex structure can be described by a clustered network. This way, we constr…
Spike timing-dependent plasticity induces non-trivial topology in the brain
Rafael R. Borges, Fernando S. Borges, Ewandson L. Lameu +5
We study the capacity of Hodgkin-Huxley neuron in a network to change temporarily or permanently their connections and behavior, the so called spike timing-dependent plasticity (ST…
Effects of the spike timing-dependent plasticity on the synchronisation in a random Hodgkin-Huxley neuronal network
R. R. Borges, F. S. Borges, A. M. Batista +5
In this paper, we study the effects of spike timing-dependent plasticity on synchronisation in a network of Hodgkin-Huxley neurons. Neuron plasticity is a flexible property of a ne…
Network induces burst synchronisation in cat brain
Ewandson L. Lameu, Fernando S. Borges, Rafael R. Borges +3
The brain of mammals are divided into different cortical areas that are anatomically connected forming larger networks which perform cognitive tasks. The cat cerebral cortex is com…
