SAM系统对TDCS数据的优化处理与深层应用 Title:OptimizationandDeepApplicationsofSAMSystemforTDCSData Introduction: Transcranialdirectcurrentstimulation(TDCS)isanon-invasivebrainstimulationtechniquethatmodulatescorticalexcitability,makingitapromisingtoolforcognitiveenhancement,neuropsychiatricdisorders,andrehabilitation.However,tofullyunleashthepotentialofTDCS,thereisaneedforadvanceddataprocessingtechniquesanddeepapplications.ThispaperaimstoexploretheoptimizationanddeepapplicationsoftheSAMsystemforTDCSdata. OptimizationoftheSAMSystemforTDCSData: TheSignalAnalysisandMapping(SAM)systemiswidelyusedinTDCSresearchforthecollectionandanalysisofbrainsignaldata.TooptimizetheSAMsystemforTDCSdata,severalaspectsneedtobeconsidered: 1.Noisereduction:TDCSsignalsareoftencontaminatedbyvarioussourcesofnoise,includingartifactsfromelectrodecontactsandphysiologicalnoise.Advancednoisereductiontechniques,suchasadaptivefilteringandsignalaveraging,canbeemployedtoimprovethequalityofthecollecteddata. 2.Featureselection:TDCSdataoftencontainalargenumberoffeatures,whichcanbechallengingforanalysisandinterpretation.Featureselectionalgorithms,suchasPrincipalComponentAnalysis(PCA)andRecursiveFeatureElimination(RFE),canbeutilizedtoidentifythemostinformativefeatures,reducingthecomputationalburdenandimprovingtheperformanceofsubsequentanalyses. 3.Calibrationandnormalization:TDCSdatacollectedfromdifferentindividualsmayvaryintermsofamplitudeandbaselinecharacteristics.Calibrationandnormalizationtechniques,suchasz-scorenormalizationandreferenceelectrodestandardizationtechniques(REST),canbeappliedtoensurethecomparabilityandreliabilityofTDCSdataacrosssubjectsandsessions.
