• Breathtaking brains Intrinsic neural adaptations to hypoxia 

      Geiseler, Samuel (Doctoral thesis; Doktorgradsavhandling, 2016-04-07)
      To maintain and restore the membrane potential that is crucial for normal function of neurons, the brain requires a constant and high energy supply. This supply is mainly covered by oxidative metabolism. When oxygen supply is impaired on a cellular level (hypoxia), such as in the case of stroke, neural energy levels become inadequate to maintain ion balance, leading to excessive ion flux and ultimately ...
    • Disassembly and Mislocalization of AQP4 in Incipient Scar Formation after Experimental Stroke 

      Banitalebi, Shervin; Skauli, Nadia; Geiseler, Samuel; Ottersen, Ole Petter; Amiry-Moghaddam, Mahmood (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-01-20)
      There is an urgent need to better understand the mechanisms involved in scar formation in the brain. It is well known that astrocytes are critically engaged in this process. Here, we analyze incipient scar formation one week after a discrete ischemic insult to the cerebral cortex. We show that the infarct border zone is characterized by pronounced changes in the organization and subcellular ...
