The cerebellum has a complex network and relates to various clinical functions including ataxia, gait disturbance, hearing and vision, cognition and affective control. Cerebellar peduncles are the structure connecting the cerebellum to the brain stem and the cerebrum. There exist three cerebellar peduncles. The superior cerebellar peduncle （SCP） involves vestibular sense and proprio- ception connecting to the thalamocortical pathway. The middle cerebellar peduncle （MCP） is the largest structure among the three cerebellar peduncles conveying impulses from the cerebral cortex to the cerebellum through corticopontocerebellar tract.

In this study, we analyzed diffusion tensor imaging （dti） results of brain white matter in rhesus macaques （Macaca mulatta） with four different parameter settings and found that the sequence A （b=1000 s/mm^2, spatial resolution=1.25 mm ×1.25 mm× 1.25 mm, numbers of direction=33, NSA=3） and B （b=800 s/mm^2, spatial resolution= 1.25 mm× 1.25 mm× 1.25 mm, numbers of direction=33, NSA=3） could accurately track coarse fibers. The fractional anisotropy （FA） derived from sequence C （b=1000s/mm^2, spatial resolution=0.55 mm×0.55 mm×2.5 mm, direction number=33, NSA=3） was too fuzzy to be used in tracking white matter fibers. By comparison, the high resolution and the FA with high contrast of gray matter and white matter derived from sequence D （b=800 s/mm^2, spatial resolution=1.0 mm×1.0 mm ×1.0 mm, numbers of direction=33, NSA=3） qualified in its application in tracking both thick and thin fibers, making it an optimal dti setting for rhesus macaques.

Accurately documenting and quantifying peripheral nerve axonal degeneration and regeneration is critically important for clinical research in peripheral nerve disorders such as nerve trauma, peripheral neuropathy and amyotrophic lateral sclerosis （ALS）. Current strategies include clinical assessments and neurophysiological studies （including nerve conduction studies and electromyography （EMG））. However, the information provided by these strategies is limited in a number of ways.

The interaction between an electron and an elastic wave is investigated for HgTe and InAs-GaSb quantum wells. The well-known Bernevig Hughes-Zhang model, i.e., the 4 × 4 model for a two-dimensional （2D） topological insulator （TI）, is extended to include the terms that describe the coupling between the electron and the elastic wave. The influence of this interaction on the transport properties of the 2dti and of the edge states is discussed. As the electron-like and hole-like carriers interact with the elastic wave differently due to the crystal symmetry of the 2dti, one may utilize the elastic wave to tune^control the transport property of charge carriers in the 2dti. The extended 2dti model also provides the possibility to investigate the backscattering of edge states of a 2dti more realistically.

The cingulum,the neural tract connecting the orbitofrontal cortex with the medial temporal lobe,plays an important role in cognition（Bush et al.,2000）.It is also important in memory because it provides cholinergic innervations to the cerebral cortex after obtaining innervation from the medial septal nucleus,the vertical nucleus of the diagonal band, and the nucleus basalis of Meynert via the medial cholinergic pathway （Nieuwenhuys et al., 2008; Naidich and Duvernoy, 2009; Hong and Jang, 2010a）.

Motor weakness is one of the most serious disabling sequelae of stroke. For successful rehabilitation, thorough estimation of the state of injured neural tracts for motor function is mandatory. After development of diffusion tensor tractogra- phy （DTT）, which is derived from diffusion tensor imaging （dti）, three-dimensional reconstruction and estimation for three motor tracts, such as the corticospinal tract, the rubrospinal tract, and the corticoreticular pathway became possible （Kunimatsu et al., 2004; Puig et al., 2010; Yang et al., 2011）. The corticospinal tract is known to be a major neural tract for motor function in the human brain （Binkofski et al., 1996）.

Tensor interpolation is a key step in the processing algorithms of diffusion tensor imaging (dti), such as registration and tractography. The diffusion tensor (DT) in biological tissues is assumed to be positive definite. However, the tensor interpolations in most clinical applications have used a Euclidian scheme that does not take this assumption into account. Several Rie-mannian schemes were developed to overcome this limitation. Although each of the Riemannian schemes uses different metrics, they all result in a ‘fixed’ interpolation profile that cannot adapt to a variety of diffusion patterns in biological tissues. In this paper, we propose a DT interpolation scheme to control the interpolation profile, and explore its feasibility in clinical applications. The profile controllability comes from the non-uniform motion of interpolation on the Riemannian geodesic. The interpolation experiment with medical dti data shows that the profile control improves the interpolation quality by assessing the reconstruction errors with the determinant error, Euclidean norm, and Riemannian norm.

The fornix, which is involved in transfer of episodic memory, is an important structure of the Papez circuit between the medial diencephalon and the medial temporal lobe. Many studies using dti have reported on injury of the fornix in patients with brain injury （Nakayama et al., 2006; Sugiyama et al., 2007; Wang et al., 2008; Chang et al., 2010）. However, only a few studies on recov- ery of an injured fornix in patients with brain injury, including traumatic brain injury and stroke, have been reported （Yeo et al., 2011; Yeo and Jang, 2013a, b）. In this study, using follow up DTT images, we reported on a patient who showed recovery of injured fornical crura following a neurosurgical operation for a brain tumor.
