Temporal Processing in Primate Motor Control : Relation Between Cortical and EMG Activity by Olivier F. L. Manette and Marc A. Maier

27sept07

Abstract—We investigated spatio-temporal information processing in the primate motor system. Corticomotoneuronal (CM) cells provide monosynaptic excitatory connections from motor cortex to spinal motoneurons and contribute causally to the time-varying electromyogram (EMG) of their target muscle. A multilayer perceptron (MLP) was used to evaluate the transfer function between neural activity of single CM cells and their [...]

TempUnit: A bio-inspired neural network model for signal processing By Olivier FL. Manette, Marc A. Maier

27sept07

Abstract – We have developed and tested a novel artificial neural network for the processing of temporal signals. The working of the units (TempUnit) is based on the mechanism of temporal summation as observed in biological neurons. Its particularity is to adapt its basis function by supervised learning. The model was tested on cortical and [...]
