BSDR Player (Bilateral Sounds Desensitization and Reprocessing) is an application that generates bilateral beeps. It is based on bilateral stimulation (a way of stimulating the brain one side at a time) and EMDR (Eye Movement Desensitization and Reprocessing). These techniques can produce a direct effect on the way the brain processes or re-processes past emotional experiences. You can use this application to aid in the treatment of traumas, process upsetting situations, disturbing thoughts, improve future performance, or simply feel better. Studies done with patients undergoing EMDR while in CAT scans have shown physiological changes in the brain that lead to adaptive changes in thinking and emotional self-regulation. "A study comparing the effectiveness of Prozac vs. EMDR showed that EMDR was more successful than Prozac in achieving substantial and sustained reductions in anxiety and depression." - The Journal of Clinical Psychiatry, January 2007
