2. 1. Spinal cord repair strategies

   Author : Henrich Cheng; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Spinal cord; injury; paraplegia; repair; regeneration; nerve graft; fibrin glue; aFGF; GDNF; gait; axonal tracing Henrich Cheng; 1996;

   Abstract : Regeneration of long fiber tracts does not occur spontaneously in the adult mammalian brain or spinal cord. The present work is an attempt to develop a repair strategy that may overcome this lack of recovery and apply it to spinal cord injury. READ MORE

4. 2. Spinal cord injuries in Sweden : studies on clinical follow-ups

   Author : Peter Flank; Fahlström Martin; Anna Ramnemark; Richard Levi; Kerstin Wahman; Eva Denison; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Tetraplegia; paraplegia; cardiovascular disease; prevention; anthropometry; physical activity; rehabiliteringsmedicin; Rehabilitation Medicine;

   Abstract : A spinal cord injury is a serious medical condition, often caused by a physical trauma. An injury to the spinal cord affects the neurotransmission between the brain and spinal cord segments below the level of injury. The SCI causes a loss of motor function, sensory function and autonomic regulation of the body, temporary or permanent. READ MORE

5. 3. Monoaminergic modulation in spinal reflex pathways from group I afferents

   Author : Ingela Hammar; Göteborgs universitet; []
   Keywords : primary afferents; spinal interneurones; ventral spinocerebellar tract neurones; noradrenaline; serotonin; cat;

   Abstract : Serotonin and noradrenaline are known to play an important part in modulation of spinal neuronal networks. Group I muscle afferents mediate information on dynamic changes of muscle length and tension, and modulation of actions from these afferents could be of importance for the execution of movements.

6. 4. Static and Dynamic Load Response of the Lumbar Spine in Flexion

   Author : Anna-Lisa Osvalder; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomechanical response; flexion-distraction injuries; injury; ; experimental methods; spinal segments;

   Abstract : The aims of this study were to develop experimental methods for static and dynamic loading of spinal segments in vitro that would simulate flexion-distraction injuries (lap seat-belt injuries) and increase knowledge about the biomechanical response and the mechanisms of injury of the lumbar spine under static and dynamic (transient) loads in flexion. The experiments were carried out on the lumbar functional spinal unit (FSU) consisting of two adjacent vertebrae, the intervertebral disc and all intervening ligaments. READ MORE

7. 5. Functional Imaging of Spinal Locomotor Networks

   Author : Chetan Nagaraja; Klas Kullander; Gilad Silberberg; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Central pattern generators; two-photon microscopy; locomotor rhythm; multiple rhythmicities; inhibitory neurotransmission; Neuroscience; Neurovetenskap;

   Abstract : Movement is necessary for the survival of most animals. The spinal cord contains neuronal networks that are capable of motor coordination and of producing different movements. In particular, a very reduced neuronal network in the spinal cord can produce simple rhythmic outputs even in the absence of descending or sensory inputs. READ MORE
