  1. 11. The Cerebello-Olivary Feedback System

    Författare :Fredrik Bengtsson; Neurofysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropsykologi; neurofysiologi; neurophysiology; Neurology; neuropsychology; Fysiologi; Physiology; Cerebellum; Purkinje cell; Inferior olive; Neurologi; Nucleo-olivary; Climbing fibre.; Deep cerebellar nuclei;

    Sammanfattning : The pathway from the deep cerebellar nuclei to the inferior olive, the nucleo-olivary pathway, is known to be inhibitory. The physiological and temporal properties, as well as the localisation, of the nucleo-olivary pathway were characterised in the decerebrate ferret. LÄS MER

  3. 12. Superior Underwater Vision in Humans

    Författare :Anna Gislén; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; taxonomy; zoogeography; Zoologisk systematik; djurgeografi; Systematic zoology; contrast sensitivity; spatial vision; Accommodation; pupil;

    Sammanfattning : Amphibious vision is accomplished in many animals by special optical and physiological adaptations in the eyes. However, human eyes are considered to be adapted to a life in air since our curved outer cornea – which is used to refract more than two-thirds of the incoming light on land – becomes useless underwater.

  4. 13. Effects of PGC1a-induced exercise adaptations in muscle on plasticity and recovery mechanisms in the CNS

    Författare :Lars O Karlsson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; muscle; brain; exercise; transgenic; PGC-1α; FNDC5; irisin;

    Sammanfattning : In this thesis, we sought to determine if muscle-derived exercise-induced signaling via PGC-1α muscle activation influences neuroplasticity under physiological or pathophysiological conditions. For this purpose, transgenic mice with muscle-specific overexpression of PGC-1α that display an endurance exercise muscle phenotype were evaluated in models of cranial irradiation and photothrombotic stroke, as well as in aging and in a voluntary running paradigm.

  5. 14. A forage-only diet and reduced high intensity training distance in standardbred horses : growth, health and performance

    Författare :Sara Ringmark; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : This thesis examined growth, health and performance in sixteen 1.5-3-year-old Standardbred horses fed a forage-only diet and trained to race as 3-year-olds in either a control training programme (C-group) or a training programme in which the high intensity training distance was reduced by 30% (R-group).

  7. 15. Brain opioid mechanisms in amphetamine induced behaviours

    Författare :Jenny Häggkvist; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Amphetamine abuse and dependence are global health problems, affecting large numbers of individuals. Despite extensive research efforts, there has been no evidence-based pharmacotherapy available for amphetamine dependence. LÄS MER
