Figure 6From: Basal forebrain activation controls contrast sensitivity in primary visual cortexRelationship between LFP PSD ratios and contrast response changes of V1. MUA Rmax changes (Δ Rmax) were significantly correlated with both (a) low and (c) high frequency changes. Semi-saturation contrast changes (ΔC50) were (b) uncorrelated with low frequency changes but (d) showed a strong negative correlation with γ-band changes. The large symbols in (c) and (d) denote the recording locations showing either a 70 Hz peak (square), a 40 Hz peak (diamond), both peaks (star) or no peaks (dot). Correlation coefficients (r) and p-values are given on top of each plot.Back to article page
