Synchronous Chaos and Broad Band Gamma Rhythm in a Minimal Multi-Layer Model of Primary Visual Cortex
Figure 5
Pairwise crosscorrelations of spike trains and membrane potentials.
Autocorrelograms and pairwise crosscorrelograms of spiking activity and membrane potentials for three upper layer excitatory neurons. A: spiking activity, low contrast, C = 2%. B: membrane potential, low contrast, C = 2%. C: spiking activity, high contrast, C = 95%. D: membrane potential, high contrast, C = 95%. Auto- and crosscorrelograms are normalized (for zero time-lag, autocorrelograms peak at one and crosscorrelograms at the correlation coefficient). The units for the time-lag axis are ms. Colors are as in Figures 3D and 4D. Rows and columns correspond to different neurons. The angular coordinates of the three neurons are 0°, −10° and 10°.
