A flexible bio-inspired hierarchical model for analyzing musical timbre
(2016)
A flexible and multipurpose bio-inspired hierarchical model for analyzing musical timbre is presented in this paper. Inspired by findings in the fields of neuroscience, computational neuroscience, and psychoacoustics, not ...
Analyse et reconnaissance des consonnes nasales, liquides et fricatives indépendamment du locuteur pour intégration dans un système de reconnaissance automatique de parole alliant approches cognitive et statistique
(Université de Sherbrooke, 1988)
Le présent document s'intéresse à l'analyse et à la reconnaissance des consonnes nasales, liquides et fricatives indépendamment du locuteur pour les chiffres et lettres de l'alphabet en anglais. Nous proposons deux analyses ...
Audiovisual correspondence between musical timbre and visual shapes
(2014)
Abstract : This article investigates the cross-modal correspondences between musical timbre and shapes. Previously, such features as pitch, loudness, light intensity, visual size, and color characteristics have mostly been ...
High noise correlation between the functionally connected neurons in emergent V1 microcircuits
(2016)
Abstract : Neural correlations (noise correlations and cross-correlograms) are widely studied to infer functional connectivity between neurons. High noise correlations (Rsc) between neurons have been reported to increase ...
Summation of connectivity strengths in the visual cortex reveals stability of neuronal microcircuits after plasticity
(2015)
Abstract : Background: Within sensory systems, neurons are continuously affected by environmental stimulation. Recently, we showed that, on cell-pair basis, visual adaptation modulates the connectivity strength between ...
Network-selectivity and stimulus-discrimination in the primary visual cortex : cell-assembly dynamics
(2015)
Abstract : Visual neurons coordinate their responses in relation to the stimulus; however, the complex
interplay between a stimulus and the functional dynamics of an assembly still eludes
neuroscientists. To this aim, ...
Stimulus-dependant augmented gamma oscillatory activity between the functionally connected cortical neurons in V1
Other titre : Stimulus-dependent augmented gamma oscillatory activity between the functionally connected cortical neurons in the primary visual cortex
(2015)
Abstract : Neuronal assemblies typically synchronize within the gamma band (30-80 Hz) and are
fundamental to information processing. Despite numerous investigations, the exact mechanisms and origins of gamma oscillations ...
Reprogramming of orientation columns in visual cortex : a domino effect
(2015)
Abstract : Cortical organization rests upon the fundamental principle that neurons sharing similar properties are co-located. In the visual cortex, neurons are organized into orientation columns. In a column, most neurons ...
Objets sonores : une représentation bio-inspirée, hiérarchique, parcimonieuse à très grandes dimensions utilisable en reconnaissance
(2013)
L’accent est placé dans cet article sur la structure hiérarchique, l’aspect parcimonieux de la représentation
de l’information sonore, la très grande dimension des caractéristiques ainsi que sur l’indépendance des ...
Source separation with one ear : proposition for an anthropomorphic approach
(2005)
Abstract : We present an example of an anthropomorphic approach, in which auditory-based cues are combined with temporal correlation to implement a source separation system. The auditory features are based on spectral ...
