Comparative diffusion tractography of corticostriatal motor pathways reveals differences between humans and macaques.

The primate corticobasal ganglia circuits are understood to be segregated into parallel anatomically and functionally distinct loops. Anatomical and physiological studies in macaque monkeys are summarized as showing that an oculomotor loop begins with projections from the frontal eye fields (FEF) to the caudate nucleus, and a motor loop begins with projections from the primary motor cortex (M1)...

Connectivity-based segmentation of the striatum in Huntington's disease: vulnerability of motor pathways.

The striatum, the primary site of degeneration in Huntington's disease (HD), connects to the cerebral cortex via topographically organized circuits subserving unique motor, associative and limbic functions. Currently, it is not known whether all cortico-striatal circuits are equally affected in HD. We aimed to study the selective vulnerability of individual cortico-striatal circuits within the ...

Tracking connections between striatum, and frontal and motor cortices using diffusion tensor imaging and tractography

The striatum contributes to several motor and executive functions, such as preparation for and execution of movement, and control of goal-directed and habitual behaviour. While the connections between the striatum and cortex have been extensively studied in animals, the routes and locations of the anatomical pathways in humans have been the focus of only a handful of experiments. In this thesis...

Diffusion Properties of Cortico-Striatal White Matter Tractography As Sensistive Markers of Parkinson's Disease

Diffusion Tensor Imaging (DTI) [1] is a non-invasive imaging modality that measures the local diffusion of water molecules through biological tissues. Recently, DTI fiber tractography has been employed for the analysis of several diseases [2-4]. Yoshikawa et al. demonstrate that patients with Parkinson's disease (PD) had significantly decreased fractional anisotropy in the region along a line b...

Fronto-striatal connections in the human brain: a probabilistic diffusion tractography study.

Anatomical studies in animals have described multiple striatal circuits and suggested that sub-components of the striatum, although functionally related, project to distinct cortical areas. To date, anatomical investigations in humans have been limited by methodological constraints such that most of our knowledge of fronto-striatal networks relies on nonhuman primate studies. To better identify...
