  2. 21. Regenerating the brain : lessons from the red spotted newt

    Author : Daniel Berg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Unlike mammals, adult salamanders can regenerate their brain after injury in a process fuelled by neurogenesis. The aim of this thesis is to identify the cells that give rise to new neurons after injury and examine the mechanisms controlling the initiation and termination of brain regeneration in the newt.
