Data from: Input-dependent frequency modulation of cortical gamma oscillations shapes spatial synchronization and enables phase codingEric Lowet, Mark Roberts, Avgis Hadjipapas, Alina Peter, Jan Van Der Eerden & Peter De Weerd
Fine-scale temporal organization of cortical activity in the gamma range (~25–80Hz) may play a significant role in information processing, for example by neural grouping (‘binding’) and phase coding. Recent experimental studies have shown that the precise frequency of gamma oscillations varies with input drive (e.g. visual contrast) and that it can differ among nearby cortical locations. This has challenged theories assuming widespread gamma synchronization at a fixed common frequency. In the present study, we investigated...
Data from: Testing sensory evidence against mnemonic templatesNicholas Edward Myers, Gustavo Rohenkohl, Valentin Wyart, Mark W. Woolrich, Anna Christina Nobre & Mark G. Stokes
Most perceptual decisions require comparisons between current input and an internal template. Classic studies propose that templates are encoded in sustained activity of sensory neurons. However, stimulus encoding is itself dynamic, tracing a complex trajectory through activity space. Which part of this trajectory is pre-activated to reflect the template? Here we recorded magneto- and electroencephalography during a visual target-detection task, and used pattern analyses to decode template, stimulus, and decision-variable representation. Our findings ran counter...
Data from: Computing the local field potential (LFP) from integrate-and-fire network modelsAlberto Mazzoni, Henrik Anders Lindén, Hermann Cuntz, Anders Lansner, Stefano Panzeri, Gaute Tomas Einevoll & Henrik Lindén
Leaky integrate-and-fire (LIF) network models are commonly used to study how the spiking dynamics of neural networks changes with stimuli, tasks or dynamic network states. However, neurophysiological studies in vivo often rather measure the mass activity of neuronal microcircuits with the local field potential (LFP). Given that LFPs are generated by spatially separated currents across the neuronal membrane, they cannot be computed directly from quantities defined in models of point-like LIF neurons. Here, we explore...
Data from: Surface color and predictability determine contextual modulation of V1 firing and gamma oscillationsAlina Peter, Cem Uran, Johanna Klon-Lipok, Rasmus Roese, Sylvia Van Stijn, William Barnes, Jarrod R. Dowdall, Wolf Singer, Pascal Fries & Martin Vinck
The integration of direct bottom-up inputs with contextual information is a core feature of neocortical circuits. In area V1, neurons may reduce their firing rates when their receptive field input can be predicted by spatial context. Gamma-synchronized (30–80 Hz) firing may provide a complementary signal to rates, reflecting stronger synchronization between neuronal populations receiving mutually predictable inputs. We show that large uniform surfaces, which have high spatial predictability, strongly suppressed firing yet induced prominent gamma...
