The stria of Gennari, a densely myelinated tangential band in the primary visual cortex V1, has been shown in several high-resolution post-mortem and in-vivo MRI studies. We report the first estimates of T1 times in the stria of Gennari in-vivo. We scanned 2 subjects using the MP2RAGE sequence at 7 Tesla at an isotropic resolution of 0.5 mm. Using a novel volume-preserving cortical layering approach, we calculated the average cortical profile of T1 times in V1. We also sampled the cortex at the depth of the stria of Gennari and report the T1 times.
