Deep brain stimulation (DBS) is a neurosurgical procedure that entails the implantation of electrodes in specific brain regions, to subsequently stimulate these regions via high frequency electric impulses. This procedure is a highly effective therapeutic intervention for various severe neurological and psychiatric disorders, including Parkinson’s disease and obsessive-compulsive disorder (OCD).
Researchers at Shanghai Jiao Tong University School of Medicine and University of Cambridge recently used DBS to investigate two opposite behavioral patterns in decision-making, namely impulsivity and risk aversion.
