Fig. 4From: Early visual alterations in individuals at-risk of Alzheimer’s disease: a multidisciplinary approachCluster-based permutation test for the relationships of TF activity with visual function. Blue colors indicate negative correlations, while yellow colors indicate positive correlations. The time–frequency-sensor triplets pertaining to the significant cluster are shown in solid colors. A Correlation between visual acuity and TF in the FH + group (sensors); B correlation between visual acuity and TF in the FH + 40-60ɛ4+ group (sensors); C correlation between visual acuity and TF in the FH + group (calcarine); D correlation between visual acuity and TF in the FH + 40-60ɛ4+ group (calcarine)Back to article page
