MedicalResearch.com Interview with: Dr. Sanja Josef Golubic, dr. sc Department of Physics, Faculty of Science University of Zagreb, Croatia MedicalResearch.com: What is the background for this study? Response: Our study was aimed to search the topological biomarker of Alzheimer’s disease. A recent evidences suggest that the decades long progression of brain degeneration that is irreversible by the stage of symptomatic Alzheimer’s disease, may account for failures to develop successful disease-modifying therapies. Currently, there is a pressing worldwide search for a marker of very early, possibly reversible, pathological changes related to Alzheimer’s disease in still cognitively intact individuals, that could provide a critical opportunity for evolving of efficient therapeutic interventions. Three years ago we reported the discovery of the novel, fast brain pathway specialized for rapid processing of the simple tones. We named it gating loop. Gating loop directly links auditory brain areas to prefrontal brain area. We have also noticed the high sensitivity of the gating loop processing on AD pathology. It was inspiration to focus our Alzheimer’s disease biomarker search in the direction of prefrontal brain activation during listening of simple tones. (more…)
