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 ...
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 ...
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 ...
