A Comparative Study of Diffusion Fiber Reconstruction Models for Pyramidal Tract Branches
Frontiers in Neuroscience, 2021 Currently, comparative studies evaluating the quantification accuracy of pyramidal tracts (PT) and PT branches that were tracked based on four mainstream diffusion models are deficient.

Advanced Science, EarlyView.ARHGEF1 plays a pivotal role in both embryonic cortical neurogenesis and adult motor function. During early development, it governs genesis of deep‐layer cortical neurons by negatively regulating RAC1/CDC42‐PAK1‐Cofilin signaling. In adulthood, ARHGEF1 is important for the maintenance of neuronal morphology and activity in the motor cortex, ensuring ...

Parkinsonism in Association with Dihydropteridine Reductase Deficiency
Case Reports in Neurology, 2017 We report a 16-year-old man with disorders of tetrahydrobiopterin metabolism due to dihydropteridine reductase (DHPR) deficiency. He revealed moderate mental retardation, parkinsonism, and spastic paralysis with levodopa and 5-hydroxytryptophan (5-HTP ...

Animal Models and Experimental Medicine, EarlyView.In this study, we established a novel mouse model of intracerebral hemorrhage (ICH) by stereotactically injecting thermosensitive PNIPAM hydrogel into the internal capsule to impose localized mechanical stress on the corticospinal tract, which provides a straightforward and reproducible tool for preclinical studies on focal mechanical stress–induced ...

脳動脈瘤clipping術における運動誘発電位とindocyanine green術中血管造影併用の意義 [PDF]
, 2009 Recently, motor-evoked potential(MEP)and indocyanine green angiography(ICG-Angio) are useful monitoring in preventing neurological deficits during aneurysm clipping surgery. MEP sensitively detects ischemia of pyramidal tracts.

Brain imaging correlates of recovered swallowing after dysphagic stroke: A fMRI and DWI study
NeuroImage: Clinical, 2016 Neurogenic dysphagia frequently occurs after stroke and deglutitive aspiration is one of the main reasons for subacute death after stroke. Although promising therapeutic interventions for neurogenic dysphagia are being developed, the functional ...

The Anatomical Record, EarlyView.Abstract Nineteenth century excavations of the Ciply‐Malogne Phosphatic Chalk Formation in Hainaut, Belgium, yielded over 50 partial mosasaur skeletons, the majority of which were referred to the species Mosasaurus lemonnieri Dollo, 1889. In the years since, this taxon has experienced a complicated taxonomic history, and its exceptional hypodigm has ...

Frequency dependence of CA3 spike phase response arising from h-current properties [PDF]
, 2013 The phase of firing of hippocampal neurons during theta oscillations encodes spatial information. Moreover, the spike phase response to synaptic inputs in individual cells depends on the expression of the hyperpolarization-activated mixed cation current (
