EphrinB3/EphA4-Mediated Guidance of Ascending and Descending Spinal Tracts
The spinal cord contains many descending and ascending longitudinal tracts whose development appears to be controlled by distinct guidance systems. We identified a population of dorsal spinal neurons marked by coexpression of the transcription factor Zic2 and the guidance receptor EphA4. Zic2+;EphA4+ neurons are surrounded by mechanosensory terminals, suggesting innervation by mechanoreceptor a...
متن کاملRetrograde transport of transmissible mink encephalopathy within descending motor tracts.
The spread of the abnormal conformation of the prion protein, PrP(Sc), within the spinal cord is central to the pathogenesis of transmissible prion diseases, but the mechanism of transport has not been determined. For this report, the route of transport of the HY strain of transmissible mink encephalopathy (TME), a prion disease of mink, in the central nervous system following unilateral inocul...
متن کاملDifferential adaptation of descending motor tracts in musicians.
Between-group comparisons of musicians and nonmusicians have revealed structural brain differences and also functional differences in motor performance. In this study, we aimed to examine the relation between white matter microstructure and high-level motor skills by contrasting 2 groups of musicians with different instrument-specific motor requirements. We used diffusion tensor imaging to comp...
متن کاملC3 peptide enhances recovery from spinal cord injury by improved regenerative growth of descending fiber tracts.
Functional recovery and regeneration of corticospinal tract (CST) fibers following spinal cord injury by compression or dorsal hemisection in mice was monitored after application of the enzyme-deficient Clostridium botulinum C3-protein-derived 29-amino-acid fragment C3bot(154-182). This peptide significantly improved locomotor restoration in both injury models as assessed by the open-field Bass...
متن کاملCharacterization of Neural Activity Recorded from the Descending Tracts of the Rat Spinal Cord
A multi-electrode array (MEA) was implanted in the dorsolateral funiculus of the cervical spinal cord to record descending information during behavior in freely moving rats. Neural signals were characterized in terms of frequency and information content. Frequency analysis revealed components both at the range of local field potentials and multi-unit activity. Coherence between channels decreas...
