[HTML][HTML] Local origin of field potentials in visual cortex

S Katzner, I Nauhaus, A Benucci, V Bonin, DL Ringach… - Neuron, 2009 - cell.com
The local field potential (LFP) is increasingly used to measure the combined activity of
neurons within a region of tissue. Yet, available estimates of the size of this region are highly …

… Contrary to Niell and Stryker’s conclusion that dLGN response magnitude is unaltered by
locomotion [4], we found that locomotion onset transiently increased dLGN responses during …

GABAA inhibition controls response gain in visual cortex

S Katzner, L Busse, M Carandini - Journal of Neuroscience, 2011 - Soc Neuroscience
… Stimuli lasted 2 or 3 s and were separated by a uniform gray field (∼4 s intervals). To
measure responses, we averaged firing rate across the entire stimulus duration. … Charpak S

Temporal dynamics of neuronal modulation during exogenous and endogenous shifts of visual attention in macaque area MT

L Busse, S Katzner, S Treue - Proceedings of the national …, 2008 - National Acad Sciences
Dynamically shifting attention between behaviorally relevant stimuli in the environment is a
key condition for successful adaptive behavior. Here, we investigated how exogenous (…

Visual cortical networks: of mice and men

S Katzner, S Weigelt - Current Opinion in Neurobiology, 2013 - Elsevier
The visual cortical network consists of a number of specialized areas that are connected in
a highly structured way. Understanding the function of this network is a milestone goal of …
