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

    Författare :Jeanette Hellgren Kotaleski; KTH; []
    Nyckelord :adaptation; central pattern generator; computer simulation; inter segmental coordination; lamprey; locomotion; neural network; rhythmogenesis; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : 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. LÄS MER

  2. 2. 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

  3. 3. Computer Simulation of the Neural Control of Locomotion in the Cat and the Salamander

    Författare :Nalin Harischandra; Örjan Ekeberg; Silvia Gruhn; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Locomotion; Computer simulation; Central pattern generator; System identification; Gait transition; Sensory feedback; Spiking neural networks;

    Sammanfattning : Locomotion is an integral part of a whole range of animal behaviours. The basic rhythm for locomotion in vertebrates has been shown to arise from local networks residing in the spinal cord and these networks are known as central pattern generators (CPG). LÄS MER

  4. 4. Neural circuits engaged in mastication and orofacial nociception

    Författare :Tuija Athanassiadis; K-G Westberg; Sten Grillner; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; rhythmical jaw movements; central pattern generator; trigeminal system; rabbit; Rat; c-Fos; nociceptors; muscle pain; muscle spindle afferents; glutamate; Neurophysiology; Neurofysiologi; fysiologi; Physiology;

    Sammanfattning : A deeper understanding of both movement control and the effects of nociceptor inputs on our motor systems is critical for proper clinical diagnosis of musculo-skeletal dysfunctions and for development of novel rehabilitation schemes. In the jaw system, masticatory movements are produced by a central pattern generator (CPG) located in the brainstem. LÄS MER

  5. 5. Neural mechanisms for the control of posture, locomotion and steering : a behavioral, electrophysiological and modeling study in lamprey

    Författare :Patriq Fagerstedt; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :reticulospinal; vestibular system; spinal cord; central pattern generator; reciprocal inhibition; fictive locomotion; fictive turning; electron microscopy; computer simulation; lamprey; dorsal fin;

    Sammanfattning : When animals move around interacting with the environment, the nervous system has to solve several tasks simultaneously in order to produce and control the movements - notably propulsion, posture, balance, and associated movements. Basic motor tasks are controlled by neuronal networks organized into central pattern generators (CPGs) and reflexes, located in the spinal cord and brainstem. LÄS MER
