Figures
The signature of stimulus-driven correlations in visual cortical synaptic activity.
This figure illustrates two contrasted epochs of sub-threshold (and sometimes spiking) responses that can be measured intracellularly in the primary visual cortex of a cat during presentation of a drifting grating (left, red trace) followed by the visuo-oculomotor exploration of a natural scene (right, blue trace). The corresponding dynamics of the membrane potential fluctuations exhibit long-range correlations for the low dimension periodic stimulus (the curtain). These correlations are strongly reduced when the visual system is driven by a natural scene (see El Boustani et al., doi:10.1371/journal.pcbi.1000519).
