supraspinal การใช้

• It is a GABA receptor agonist, specifically of the supraspinal sites.
• Some scientists attribute this to a mechanism or influence downstream in the supraspinal pathways.
• The Ib sensory feedback generates spinal reflexes and supraspinal responses which control muscle contraction.
• Cerebrum ( controller ) in the head can control supraspinal signal inputs to startup, stop and turn.
• This allows the spinal CPGs to generate a scratch response targeted to the site of the stimulus independent of supraspinal structures.
• However, the brain may also provide additional ( supraspinal ) contributions, which can modulate the responsiveness of the reflex to the sensory input.
• It arises by a thin aponeurosis from the spinous processes of the thoracic and upper two or three lumbar vertebrae, and from the supraspinal ligament.
• After a SCI, supraspinal and spinal sources of control of movement differ substantially from that which existed prior to the injury, thus resulting in an altered spinal cord.
• It arises by a thin and broad aponeurosis from the lower part of the ligamentum nuchae, from the spinous processes of the seventh cervical and upper two or three thoracic vertebrae and from the supraspinal ligament.
• Compared to young adults, old adults exhibit muscle fatigue ( peripheral fatigue ) resistance during sustained isometric maximal voluntary contraction, but they show greater supraspinal fatigue at start of sustained task, and during recovery.
• However, as this asymmetric control is observed without phasic sensory feedback, supraspinal structures, pharmacology, or sustained simulation, then a number of systems can potentially modulate the generator to produce different modes of phase-cycle period changes.
• The main purpose of the immersion experiments are to study effects of the flight, including unloading, on the support mechanisms of the body ( spinal, supraspinal ), the state of the central nervous systems, motor function and hand-eye co-ordination.
• The growth probably resulted from the conversion of neural spine, which projects upwards from the vertebrae, allowing muscle attachment . and " Masiakasaurus ", probably resulting from the ossification of a ligament running either between the neural spines ( interspinal ligament ) or along their tops ( supraspinal ligament ).
• Perl s first exposure to neuroscience came at the University of Illinois School of Medicine's Illinois Neuropsychiatric Institute ( Chicago ), where he worked for a time as a part-time graduate student in Warren S . McCulloch s laboratory and where he met, among other notables of the time, Elwood Henneman, whose experiments on spinal reflexes and supraspinal control of motor function were to influence Perl s later research path.
