    • Analysis of human gait using hybrid EEG-fNIRS-based BCI system: A review 

      Khan, Haroon; Naseer, Noman; Yazidi, Anis; Eide, Per Kristian; Hassan, Wajahat; Mirtaheri, Peyman (Peer reviewed; Journal article, 2021)
      Human gait is a complex activity that requires high coordination between the central nervous system, the limb, and the musculoskeletal system. More research is needed to understand the latter coordination's complexity in ...

    • Brain-wide glymphatic enhancement and clearance in humans assessed with MRI 

      Ringstad, Geir; Valnes, Lars Magnus; Dale, Anders; Pripp, Are Hugo; Vatnehol, Svein Are Sirirud; Emblem, Kyrre Eeg; Mardal, Kent-Andre; Eide, Per Kristian (JCI Insight;Volume 3, Issue 13, Journal article; Peer reviewed, 2018-07-12)
      To what extent does the subarachnoid cerebrospinal fluid (CSF) compartment communicate directly with the extravascular compartment of human brain tissue? Interconnection between the subarachnoid CSF compartment and brain ...

    • Impaired glymphatic function in idiopathic intracranial hypertension 

      Eide, Per Kristian; Pripp, Are Hugo; Ringstad, Geir; Valnes, Lars Magnus (Brain Communications;Volume 3, Issue 2, Peer reviewed; Journal article, 2021-03-21)
      Idiopathic intracranial hypertension is a brain disease incorporating cerebrospinal fluid disturbance, increased intracranial pressure and visual failure, but with unknown cause. This study examined a hypothesis that ...

    • In vivo distribution of cerebrospinal fluid tracer in human upper spinal cord and brain stem 

      Melin, Erik; Pripp, Are Hugo; Eide, Per Kristian; Ringstad, Geir (Peer reviewed; Journal article, 2023)
      BACKGROUND. Intrathecal injection is an attractive route through which drugs can be administered and directed to the spinal cord, restricted by the blood-spinal cord barrier. However, in vivo data on the distribution of ...

    • Physiological alterations of pineal recess crowding in symptomatic non-hydrocephalic pineal cysts 

      Eide, Per Kristian; Lindstrøm, Erika Kristina; Pripp, Are Hugo; Valnes, Lars Magnus; Ringstad, Geir (Peer reviewed; Journal article, 2023)
      Pineal cysts are prevalent in the population. Due to more widespread use of magnetic resonance imaging, an increasing number of symptomatic patients with non-hydrocephalic pineal cysts are referred to neurologists and ...

    • Plasma neurodegeneration biomarker concentrations associate with glymphatic and meningeal lymphatic measures in neurological disorders 

      Eide, Per Kristian; Lashkarivand, Aslan; Pripp, Are Hugo; Valnes, Lars Magnus; Hovd, Markus Herberg; Ringstad, Geir; Blennow, Kaj; Zetterberg, Henrik (Peer reviewed; Journal article, 2023)
      Clearance of neurotoxic brain proteins via cerebrospinal fluid (CSF) to blood has recently emerged to be crucial, and plasma biomarkers of neurodegen- eration were newly introduced to predict neurological disease. This ...

    • Prevalence of pineal cysts in healthy individuals: Emphasis on size, morphology and pineal recess crowding 

      Warsza, Bogna; Due-Tønnessen, Pernille; Due-Tønnessen, Paulina; Pripp, Are Hugo; Ringstad, Geir; Eide, Per Kristian (Peer reviewed; Journal article, 2023)
      The present study aimed to determine prevalence of non-hydrocephalic pineal cysts of different size and morphology in healthy individuals. In a cohort of healthy individuals who as part of research volunteered to undergo ...

    • Prospective T1 mapping to assess gadolinium retention in brain after intrathecal gadobutrol 

      Ringstad, Geir; Valnes, Lars Magnus; Vatnehol, Svein Are Sirirud; Pripp, Are Hugo; Eide, Per Kristian (Peer reviewed; Journal article, 2023)
      Purpose A possible pathway behind gadolinium retention in brain is leakage of contrast agents from blood to cerebrospi- nal fluid and entry into brain along perivascular (glymphatic) pathways. The object of this study was ...
