Zusammenfassung:
The primary visual cortex V1 is the elementary target, when visual function and cortical reorganization are investigated. The study demonstrates that online analysis of field distributions is helpful to assess local spectral quality. At 7T metabolite line widths of less than 10Hz could be reproducibly achieved, when regions of field disturbances were avoided. Profiting from 3D field analysis and a combination coil setup at high field, the feasibility of localized single voxel spectroscopy in the primary visual cortex (1.5-1.7mm diameter) was demonstrated in the macaque monkey.
