Journal ArticleDOI
Orientation selectivity and the functional clustering of synaptic inputs in primary visual cortex.
TL;DR: In vivo two-photon calcium imaging was used to characterize the orientation tuning and spatial arrangement of synaptic inputs to the dendritic spines of individual pyramidal neurons in layer 2/3 of ferret visual cortex, showing a robust input–output nonlinearity that could not be explained by spike threshold alone.
Journal ArticleDOI
Distributed network interactions and their emergence in developing neocortex.
Gordon B. Smith,Bettina Hein,David E. Whitney,David Fitzpatrick,Matthias Kaschube,Matthias Kaschube +5 more
TL;DR: It is suggested that local connections in early cortical circuits can generate structured long-range network correlations that guide the formation of visually evoked distributed functional networks.
Journal ArticleDOI
Modular Representation of Luminance Polarity in the Superficial Layers of Primary Visual Cortex
TL;DR: It is concluded that polarity selectivity is an integral feature of layer 2/3 neurons, ensuring that the distinction between light and dark stimuli is available for further processing in downstream extrastriate areas.
Journal ArticleDOI
Experience-Dependent Reorganization Drives Development of a Binocularly Unified Cortical Representation of Orientation.
TL;DR: While orderly modular networks of orientation preference initially arise independent of visual experience, experience is critical for the alignment of these early representations and experience-dependent processes drive reorganization of these three representations.
Journal ArticleDOI
Functional Connectivity of Resting Hemodynamic Signals in Submillimeter Orientation Columns of the Visual Cortex
TL;DR: The results suggest that temporal coherence of hemodynamic signals measured by optical imaging of intrinsic signals exists at a submillimeter columnar scale in resting state, suggesting that thestrength of resting connectivity is related to the strength of the visual stimulation response.
