We measured in vivo human brain T₂^* values using 7T MRI at 0.35 × 0.35 × 0.35 mm³. We simultaneously targeted calcarine sulcus and Heschl’s gyrus. Our results show that gray matter T₂^* varies up to 15 ms (global range being mostly in between 25-45 ms) from deep to superficial layers. The stria of Gennari shows up as a major reduction of T₂^* within calcarine sulcus. However, a similar layering is not visible within Heschl’s gyrus. B₀ alignment effects seem to be not as strong as the biological tissue composition effects that are observed across the visual and auditory regions.
