A neural circuit for gamma-band coherence across the retinotopic map in mouse visual cortex
Cortical gamma oscillations have been implicated in a variety of cognitive, behavioral, and circuit-level phenomena. However, the circuit mechanisms of gamma-band generation and synchronization across cortical space remain uncertain. Using optogenetic patterned illumination in acute brain slices of mouse visual cortex, we define a circuit composed of layer 2/3 (L2/3) pyramidal cells and somatos...
متن کاملAn extended retinotopic map of mouse cortex
Visual perception and behavior are mediated by cortical areas that have been distinguished using architectonic and retinotopic criteria. We employed fluorescence imaging and GCaMP6 reporter mice to generate retinotopic maps, revealing additional regions of retinotopic organization that extend into barrel and retrosplenial cortices. Aligning retinotopic maps to architectonic borders, we found a ...
متن کاملThe role of EphrinA for retinotopic map formation in mouse visual cortex
Acknowledgements Most of all, I want to thank Mark Hübener who faithfully and patiently supported me and helped me wherever he could. He taught me a great deal about imaging, about the visual cortex, and about science in general. Mark's enthusiasm and humour are very contagious and he stimulated my own thoughts and ideas and was great fun to work, discuss and laugh with. I am indebted to Sven S...
متن کاملMapping retinotopic structure in mouse visual cortex with optical imaging.
We have used optical imaging of intrinsic signals to visualize the retinotopic organization of mouse visual cortex. The functionally determined position, size, and shape of area 17 corresponded precisely to the location of this area as seen in stained cortical sections. The retinotopic map, which was confirmed with electrophysiological recordings, exhibited very low inter-animal variability, th...
متن کاملLayer-Specific Entrainment of Gamma-Band Neural Activity by the Alpha Rhythm in Monkey Visual Cortex
Although the mammalian neocortex has a clear laminar organization, layer-specific neuronal computations remain to be uncovered. Several studies suggest that gamma band activity in primary visual cortex (V1) is produced in granular and superficial layers and is associated with the processing of visual input. Oscillatory alpha band activity in deeper layers has been proposed to modulate neuronal ...
