  2. 1. Evolution and Pharmacology of Neuropeptide Y Receptors, Implications for vertebrate genome duplications

    Author : Robert Fredriksson; Susanne Holmgren; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; Evolution; tetraploidizations; G-protein coupled receptor; neuropeptide Y; zebrafish; chicken; rainbow trout; lamprey; genome duplications; peptide YY; pancreatic polypeptide; Neurovetenskap; Neurology; Neurologi; medicinsk farmakologi; Medical Pharmacology;

    Abstract : The Y receptors comprise a family of evolutionarily related receptors belonging to the superfamily of G-protein coupled receptors (GPCR). Their natural ligands are in mammals neuropeptide Y (NPY), peptide YY (PYY) and pancreatic polypeptide (PP). READ MORE

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

    Author : Jeanette Hellgren Kotaleski; KTH; []
    Keywords : 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

  5. 3. Computational modeling of the lamprey CPG : from subcellular to network level

    Author : Mikael Huss; Jeanette Hellgren Kotaleski; Anders Lansner; Ranu Jung; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datalogi;

    Abstract : Due to the staggering complexity of the nervous system, computer modelling is becoming one of the standard tools in the neuroscientist's toolkit. In this thesis, I use computer models on different levels of abstraction to compare hypotheses and seek un- derstanding about pattern-generating circuits (central pattern generators, or CPGs) in the lamprey spinal cord.

  6. 4. Vestibular control of body orientation in lamprey

    Author : Elena Pavlova; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Postural control; orientation; vision; vestibular system; visuo-vestibular interaction; vestibular compensation; locomotion; supraspinal control; lamprey;

    Abstract : Maintenance of body orientation (postural control) is a vital motor function of the brain. The general goal of this project was to understand the organization and operation of neuronal networks responsible for postural control. The lamprey (a lower vertebrate) was used as a model animal.
