“…Structural neuroimaging techniques revealed increased amounts of gray matter volume (GMV) as surrogate for enhanced neuroplasticity in relation to motoric training, cognitive performance or treatment with the antidepressant fluoxetine, a selective serotonin reuptake inhibitor (Draganski et al, 2004;Kanai and Rees, 2011;Vetencourt et al, 2008). On the other side, GMV loss as measured with highresolution structural magnetic resonance imaging (MRI), is a key feature of neuropsychiatric brain disorders, whereby the hippocampal formation was demonstrated to be especially vulnerable to volumetric alterations (Benninghoff et al, 2010;Geuze et al, 2005).…”
