Red Neuronal Creciente Usando Perturbación Simultánea
Información tecnológica, 2004 Este articulo propone una red neuronal de tipo perceptron multicapas (MLP) que optimiza tanto su matriz de pesos como el numero de neuronas ocultas. Inicialmente el sistema propuesto usa un numero reducido de neuronas ocultas, optimizandose la matriz de pesos mediante un algoritmo de perturbacion simultanea.

Logarithmic distributions prove that intrinsic learning is Hebbian
, 2017 In this paper, we present data for the lognormal distributions of spike rates, synaptic weights and intrinsic excitability (gain) for neurons in various brain areas, such as auditory or visual cortex, hippocampus, cerebellum, striatum, midbrain nuclei ...

Striking circadian neuron diversity and cycling of Drosophila alternative splicing. [PDF]
, 2018 Although alternative pre-mRNA splicing (AS) significantly diversifies the neuronal proteome, the extent of AS is still unknown due in part to the large number of diverse cell types in the brain.
