Histology does not allow quantitative investigation of
structural connectivity on a whole-brain level, in
contrast to MRI techniques such as Diffusion Tensor
Imaging (DTI). Recently, an in vivo DTI study revealed a
novel sexual dimorphism in the zebra finch brain. In
order to achieve a precise understanding of the
anatomical substrate underlying the observed difference,
we propose to use super-resolution DTI (SR-DTI) and
track density imaging (TDI). We show that by combining
SR-DTI and TDI, a clear anatomical contrast of song
control system connectivity as well as a clear
delineation of its different components can be realized.
