面向脑状态监测的脑电与脑氧信号采集系统的开题报告 Title:BrainStateMonitoringSystembasedonEEGandNIRSSignalAcquisition Abstract: Brain-computerinterfacetechnologyhasdevelopedrapidlyinrecentyears,whichhasbroughtmoreattentiontobrainsignalacquisitionsystems.Inordertomonitorandanalyzebrainstate,someadvancedbrainsignalacquisitiondevices,suchaselectroencephalography(EEG)andnear-infraredspectroscopy(NIRS),havebeenwidelyusedinvariousfields.Therefore,abrainstatemonitoringsystembasedonEEGandNIRSsignalacquisitionisproposedinthisreport.Thisproposedsystemaimstocollectreal-timedataofbrainactivityandprovideinsightsintocognitiveandemotionalstates.Thedesign,workingprinciples,andpotentialapplicationsoftheproposedsystemarediscussedindetail. Introduction: Brainsignalacquisitionsystemsenablethemeasurementandrecordingofbrainactivities,whichareessentialformonitoringbrainfunctions,diagnosisofneurophysiologicaldisorders,anddevelopingvariousapplicationsusingbrain-computerinterfaces.Thecombinationofthesetwotypesofsignalscanprovideaholisticviewofthebrainactivitiesbydetectingbothelectricalactivityandhemodynamicchangesofthebrain.Basedontheseobservations,theproposedsystemcanquicklyandaccuratelymonitorbrainstatesandofferreal-timefeedbackonusers'cognitivestatus.Thisreportprovidesacomprehensiveoverviewoftheproposedsystem'sdesign,workingprinciples,andpotentialapplications.
