  1. 1. Analysis of different forms of locomotor behavior in lamprey

    Författare :Salma Sanzida Islam; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Motor coordination; undulatory locomotion; postural corrections; spinal cord damage; lamprey;

    Sammanfattning : The ability to locomote, that is move actively in space, is characteristic of the animal kingdom. Many species are capable of different forms of locomotion. They include forward and backward locomotion, fast and slow progression, etc. LÄS MER

  3. 2. 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

  4. 3. Behavioral effects of female sex steroid hormones : models of PMS and PMDD in Wistar rats

    Författare :Magnus Löfgren; Torbjörn Bäckström; Inga-Maj Johansson; Per Södersten; Umeå universitet; []

    Sammanfattning : Background Animal models can be used to mimic human conditions of psychopathology, and also as pre-clinical models to evaluate candidate drugs. With hormonal treatment it is possible to produce behavior in the rat which corresponds to the mental symptoms of pre-menstrual syndrome (PMS), and pre-menstrual dysphoric disorder (PMDD). LÄS MER

  5. 4. Distribution and modulatory roles of neuropeptides and neurotransmitters in the Drosophila brain

    Författare :Lily Kahsai Tesfai; Åsa M. E. Winther; Ronald Strauss; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; central complex; locomotor behavior; co-transmitter; metabotropic receptor; metabolic stress; Neurobiology; Neurobiologi; zoologi; Zoology;

    Sammanfattning : The central complex is a prominent neuropil found in the middle of the insect brain. It is considered as a higher center for motor control and information processing. LÄS MER

  7. 5. How can an organism´s life experience affect their descendants? Insights from epigenetic and transgenerational effects of chemical exposure in zebrafish

    Författare :Mélanie Blanc; Steffen Keiter; Joëlle Rüegg; Xavier Cousin; Nikolai Scherbak; Michael K. Skinner; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Neurotoxicity; behavior; RNA-Seq; RRBS; TEI; permethrin; PCBs; PBDEs; coumarin 47;

    Sammanfattning : Environmental pollution causes approx. 10% of human diseases, and some develop in the progeny because of parental exposure. Effects passed on to subsequent generations may be a consequence of genetic mutations, or of inherited changes in epigenetic patterns. LÄS MER
