  4. 2. Complexity and Change in a Simple Food Web : Studies in the Baltic Sea (FAO Area 27.IIId)

    Author : Henrik Österblom; Sture Hansson; Robert W Furness; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Avian cholera; Bottom-up; Bycatch; Clupea harengus; Ecosystem; Food web; Gadus morhua; Halichoerus grypus; Regime shift; Sprattus sprattus; Top-down; Trophic cascade; Uria aalge; Marine ecology; Marin ekologi;

    Abstract : An influence at one trophic level can result in dynamic impacts also on other components of a food web. These dynamics are known as trophic cascades, and can be both top-down and bottom-up. After a near-collapse of the Baltic cod Gadus morhua stock in the 1980s, its main prey sprat Sprattus sprattus increased dramatically. READ MORE

  5. 3. Deep brain stimulation in obsessive-compulsive disorder

    Author : Matilda Naesström; Owe Bodlund; Patric Blomstedt; Johan Eriksson; Lotta M. J. Strömsten; Ellinor Salander Renberg; Keith Matthews; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; deep brain stimulation DBS ; obsessive-compulsive disorder OCD ; psykiatri; Psychiatry;

    Abstract : Deep brain stimulation (DBS) is under investigation for severe obsessive-compulsive disorder (OCD) resistant to other therapies. As a crucial part of the anxiety circuit in the brain, the bed nucleus of stria terminalis (BNST) has been proposed as a target for DBS in OCD. READ MORE
