  1. 1. Modeling of bursting mechanisms and coordination in a spinal central pattern generator

    University dissertation from Stockholm : KTH

    Author : Jeanette Hellgren Kotaleski; KTH.; [1998]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; adaptation; central pattern generator; computer simulation; inter segmental coordination; lamprey; locomotion; neural network; rhythmogenesis; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Mechanisms underlying lotal bursting as well as coordinationbetween different levels of a spinal CPG generating locomotionhave been investigated using computer simulations. A"primitive" jawless vertebrate, the lamprey, is used a.s aprototype model. READ MORE

    Abstract : Spinal neurons are important in several aspects motor control. For example, the neurons essential for locomotor movements reside in the ventral spinal cord. In this thesis, different motor control functions are being related to neuronal populations defined by their common expression of a gene. READ MORE

  3. 3. Statistical Downscaling of Precipitation from Large-scale Atmospheric Circulation Comparison of Methods and Climate Regions

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Fredrik Wetterhall; Uppsala universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hydrology; Statistical; Downscaling; Precipitation; Large-scale circulation; PCA; TWS; Weather pattern; Regression; Weather generator; Hydrologi; NATURAL SCIENCES Earth sciences Atmosphere and hydrosphere sciences Hydrology; NATURVETENSKAP Geovetenskap Atmosfärs- och hydrosfärsvetenskap Hydrologi;

    Abstract : A global climate change may have large impacts on water resources on regional and global scales. General circulation models (GCMs) are the most used tools to evaluate climate-change scenarios on a global scale. They are, however, insufficiently describing the effects at the local scale.

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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Sharn Perry; Uppsala universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Locomotion; central pattern generator; mouse; gait; recurrent inhibition; Renshaw cell; Dmrt3; Chrna2; Neuroscience; Neurovetenskap;

    Abstract : 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. READ MORE

  5. 5. Computer Simulation of the Neural Control of Locomotion in the Cat

    University dissertation from Stockholm : KTH

    Author : Nalin Harischandra; KTH.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Locomotion; Computer simulation; Central pattern generator; Muscle activation; Linear transfer functions; Sensory feedback; Neural control; TECHNOLOGY Information technology Computer science; TEKNIKVETENSKAP Informationsteknik Datavetenskap;

    Abstract : Locomotion is one of the most important behaviours and requires interaction between sensors at various levels of the nervous system and the limb muscles of an animal. The basic neural rhythm for locomotion in mammals has been shown to arise from local neural networks residing in the spinal cord and these networks are known as central pattern generators (CPGs).
