Each ommatidium of the Drosophila eye is constructed by precisely 19 specified precursor cells, generated in part during a second mitotic wave of cell divisions that overlaps early stages of ommatidial cell specification. Homozygotes for the pineapple eye mutation lack sufficient precursor cells due to apoptosis during the period of fate specification. In(More)
For neurorehabilitation of patients with spinal cord injury (SCI), the traditional emphasis on social adaptation is being expanded to include strategies that promote plasticity and regeneration in the central nervous system. Such strategies are needed to optimize recovery of neurological function. For example, the known dependence of most cellular processes(More)
The rehabilitation of spinal cord injury (SCI) is a complicated process, but one in which new research is developing novel and increasingly promising methods of restorative neurology. Spinal cord injury medicine addresses not only the neurologic injury, but all the secondary complications in other organ systems whose regulation is disrupted after SCI. To(More)
BACKGROUND Recovering upper-limb motor function has important implications for improving independence of patients with tetraplegia after traumatic spinal cord injury (SCI). OBJECTIVE To evaluate the feasibility, safety and effectiveness of robotic-assisted training of upper limb in a chronic SCI population. METHODS A total of 10 chronic tetraplegic SCI(More)
OBJECTIVE To investigate the effects of anodal transcranial direct current stimulation (a-tDCS) intensity on corticospinal excitability and affected muscle activation in individuals with chronic spinal cord injury (SCI). DESIGN Single-blind, randomized, sham-controlled, crossover study. SETTING Medical research institute and rehabilitation hospital. (More)
: Hydrocephalus is a rare complication of traumatic spine injury. A literature review reflects the rare occurrence with cervical spine injury. We present a case of traumatic injury to the lumbar spine from a gunshot wound, which caused communicating hydrocephalus. The patient sustained a gunshot wound to the lumbar spine and had an L4-5 laminectomy with(More)
BACKGROUND After cervical spinal cord injury, current options for treatment of upper extremity motor functions have been limited to traditional approaches. However, there is a substantial need to explore more rigorous alternative treatments to facilitate motor recovery. OBJECTIVE To demonstrate whether anodal-primary motor cortex (M1) excitability(More)
