Summation of connectivity strengths in the visual cortex reveals stability of neuronal microcircuits after plasticity
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 ...
High noise correlation between the functionally connected neurons in emergent V1 microcircuits
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 ...
Network-selectivity and stimulus-discrimination in the primary visual cortex : cell-assembly dynamics
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
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
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 ...
Synergistic activity between primary visual neurons
Abstract : Cortical microcircuitry plays a pivotal role in encoding sensory information reaching the cortex. However, the fundamental knowledge concerning the mechanisms that govern feature-encoding by these sub-networks ...
Modulation of functional connectivity following visual adaptation: homeostasis in V1
Abstract: Sensory neurons exhibit remarkable adaptability in acquiring new optimal selectivity to unfamiliar features when a new stimulus becomes prevalent in the environment. In conventionally prepared adult anesthetized ...
A flexible bio-inspired hierarchical model for analyzing musical timbre
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 ...
Audiovisual correspondence between musical timbre and visual shapes
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 ...
