1. 1. Functional Imaging of Spinal Locomotor Networks

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

   Sammanfattning : 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. LÄS MER

3. 2. Crossing the Midline : Locomotor Neuronal Circuitry Formation

   Författare :Fatima Memic; Klas Kullander; Avihu Klar; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CPG; CIN; neuronal network; locomotion; left-right alternation;

   Sammanfattning : Networks at various levels of the nervous system coordinate different motor patterns such as respiration, eye or hand movements and locomotion. Intrinsic rhythm-generating networks that are located in the spinal cord generate motor behaviors that underlie locomotion in vertebrates. LÄS MER

4. 3. Deciphering the Locomotor Network : The Role of Spinal Cord Interneurons

   Författare :Sharn Perry; Klas Kullander; Kimberly Dougherty; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Locomotion; central pattern generator; mouse; gait; recurrent inhibition; Renshaw cell; Dmrt3; Chrna2; Neuroscience; Neurovetenskap;

   Sammanfattning : In the spinal cord, an intricate neural network generates and coordinates the patterning of limb movements during locomotion. This network, known as the locomotor central pattern generator (CPG), comprises of various cell populations that together orchestrate the output of motor neurons. LÄS MER

5. 4. Swimming with the current : Fictive locomotion reveals subtle phenotypes in the zebrafish locomotor network

   Författare :Harmen Kornelis Koning; Henrik Boije; David McLean; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; dmrt3a; wt1a; spinal cord; Mauthner cell; neural development; locomotor network; zebrafish;

   Sammanfattning : Neural networks are the functional building blocks of the central nervous system. To better understand how these networks develop and operate, we turned to the zebrafish locomotor network, with a focus on subtypes of interneurons expressing dmrt3a and wt1a. LÄS MER

7. 5. The Swedish Version of the Philadelphia Geriatric Center Multilevel Assessment Instrument (PGCMAI) : Development and testing in an old-age population with locomotor disability

   Författare :Margareta Minhage; Elisabeth Hamrin; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gender; locomotor disability; PGCMAI; old age; reliability; validity; Nursing; Omvårdnad;

   Sammanfattning : The general aim was to examine the Swedish version of the Philadelphia Geriatric Center Multilevel Assessment Instrument, PGCMAI, in a population of old people with locomotor disability in Sweden. Specific aims were to examine whether the Swedish version of the PGCMAI meets the criteria of reliability and validity when assessing the life situation of Swedish old people with locomotor disability and to explore the pattern of the Swedish version of the instrument in respect of age and gender.
