A Research On The Effect Of Short-term Cognitive Stimulation Training On Creative Brain Function Connection

As a advanced thinking activity,creative thinking is closely related to the progress and innovation of human society.All progress and innovation of human depend on innovative thinking.It is a important topic of brain science research to study the underlying neurocognitive mechanisms of cognition activity with the help of brain imaging technologies.Creative thinking is an individual thinking activity.Researchers have been exploring the neuroplasticity induced by training.Short-term Cognitive Stimulation Training(SCST)is a approach that has been shown to enhance creativity.Based on previous studies,This paper studies the performance of short-term training effects in the TTCT speech and picture scale with training intervention material for cognitive stimulus tasks.And this paper combined with electroencephalography(EEG),studies the changes of brain functional connections in different rhythms.The main contents and results are as follows:Twenty college students were selected to complete the creative SCST experiment for11 days,including TTCT verbal and pictorial creativity before and after the training,short-term cognitive stimulation training,and EEG recording of Subjects in TTCT verbal and pictorial creativity tasks.The behavioral data of subjects' TTCT verbal and pictorial creativity measurement were statistically analyzed in previous research.In this paper,the scalp electrode is traced and analyzed.46 ROIs are defined as nodes,and synchronization likelihood is selected to measure the correlation between nodes.We construct brain functional connection of subjects' TTCT verbal and pictorial creativity before and after SCST in different frequency,and to study the topological properties of functional connection.Then,we construct brain effective connectivity,and study the topological properties of effective connectivity with 16 good performance scalp electrodes selected and the correlation between nodes measured by directional transmission.In conclusion,We explored the statistical analysis of TTCT verbal and pictorial creativity scale performance and the construction and analysis of brain functionalconnectivity and effective connectivity during verbal creativity and pictorial creativity tasks.The results show the brain functional connectivity and effective connectivity of experimenters was more closely linked and the information transmission ability was higher after SCST.This short-term positive effect was mainly manifested in verbal creativity,however,effective connectivity and functional connections of verbal creativity and pictorial creativity between different rhythmic were different.This paper focuses on verbal creativity and pictorial creativity,and studied the change of functional connectivity and effective connectivity after SCST training.This study extends the research idea of traditional creativity limited to behavior,providing new evidence and perspective for short-term cognitive stimulation training and improving creativity.
