Better modulation for risk decision‐making after optimized magnetic stimulation

Traditional repetitive transcranial magnetic stimulation can only produce a significant but weak effect on the cortex while theta burst stimulation (TBS), a patterned accelerated form of stimulation, can produce a stronger poststimulation effect, which may improve decision‐making abilities. We desig...

description Traditional repetitive transcranial magnetic stimulation can only produce a significant but weak effect on the cortex while theta burst stimulation (TBS), a patterned accelerated form of stimulation, can produce a stronger poststimulation effect, which may improve decision‐making abilities. We designed a comparative assessment of the effect of intermittent TBS (iTBS), 20 Hz, in two risk decision‐making tasks on healthy controls. Participants were randomized and assigned to the iTBS (n = 29), 20 Hz (n = 29), or sham (n = 29) groups. The effects of the different methods of left dorsolateral prefrontal cortex stimulation on risk decision‐making functions were compared based on subjects’ performance in the Game of Dice Task (GDT) and Risky Gains Task (RGT). The main indicators were positive and negative feedback utilization rates of GDT and RGT. Both iTBS and 20 Hz stimulation resulted in significant improvements upon negative feedback in the GDT, with increases in safe options and reductions in risky options; iTBS stimulation increased subjects’ use of positive feedback in the GDT and RGT (all p

Furthermore, the iTBS group had a stronger feedback risk reduction effect than the 20 Hz or sham group following RGT negative feedback (p &lt; 0.05). Individuals would integrate positive and negative information more efficiently, leading to them making rational choices after excitatory transcranial magnetic stimulation. Moreover, iTBS has a stronger risk reduction effect following negative feedback than the 20Hz stimulation did. In summary, iTBS might have clinical value in decision promotion. iTBS has a stronger decision promoting effect than 20 Hz, which can be used as an effective way to alter choice and presents an improvement on standard rTMS protocols.</description><identifier>ISSN: 0360-4012</identifier><identifier>EISSN: 1097-4547</identifier><identifier>DOI: 10.1002/jnr.24772</identifier><identifier>PMID: 33617027</identifier><language>eng</language><publisher>United States: Wiley Subscription Services, Inc</publisher><subject>Decision making ; Feedback ; Game of Dice Task ; Information processing ; intermittent theta burst stimulation ; Magnetic fields ; Negative feedback ; Positive feedback ; Prefrontal cortex ; repetitive transcranial magnetic stimulation ; risk decision‐making ; Risk Gains Task ; Risk management ; Risk reduction ; Transcranial magnetic stimulation</subject><ispartof>Journal of neuroscience research, 2021-03, Vol.99 (3), p.858-871</ispartof><rights>2021 Wiley Periodicals LLC</rights><rights>2021 Wiley Periodicals LLC.</rights><rights>2021 Wiley Periodicals, Inc.</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c3532-33a0183becb5145f9ca66ddda3d0e2c81e647b7dfc1ac6faaeeeaee70b81db473</citedby><cites>FETCH-LOGICAL-c3532-33a0183becb5145f9ca66ddda3d0e2c81e647b7dfc1ac6faaeeeaee70b81db473</cites><orcidid>0000-0003-0646-1353 ; 0000-0002-6197-914X ; 0000-0002-0184-9570</orcidid></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktopdf>$$Uhttps://onlinelibrary.wiley.com/doi/pdf/10.1002%2Fjnr.24772$$EPDF$$P50$$Gwiley$$H</linktopdf><linktohtml>$$Uhttps://onlinelibrary.wiley.com/doi/full/10.1002%2Fjnr.24772$$EHTML$$P50$$Gwiley$$H</linktohtml><link.rule.ids>314,780,784,1417,27924,27925,45574,45575</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/33617027$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Wang, Lu</creatorcontrib><creatorcontrib>Wu, Xingqi</creatorcontrib><creatorcontrib>Ji, Gong‐Jun</creatorcontrib><creatorcontrib>Xiao, Guixian</creatorcontrib><creatorcontrib>Xu, Feifei</creatorcontrib><creatorcontrib>Yan, Yibing</creatorcontrib><creatorcontrib>Wu, Yang</creatorcontrib><creatorcontrib>Xi, Chunhua</creatorcontrib><creatorcontrib>Chen, Xingui</creatorcontrib><creatorcontrib>Wang, Kai</creatorcontrib><title>Better modulation for risk decision‐making after optimized magnetic stimulation</title><title>Journal of neuroscience research</title><addtitle>J Neurosci Res</addtitle><description>Traditional repetitive transcranial magnetic stimulation can only produce a significant but weak effect on the cortex while theta burst stimulation (TBS), a patterned accelerated form of stimulation, can produce a stronger poststimulation effect, which may improve decision‐making abilities.
