  • 静息态功能连接两组比较
    Mon, 02/04/2013 - 13:30wuqinjuan1
         静息态功能连接，以PCC为种子点得到功能连接网络，当AD-NC时，得到与PCC的连接明显下降，但是两组分别做单样t检验时得到的网络组成均无右侧颞上回与PCC的连接，此时能说两组的DMN存在不同吗？还是说功能连接网络存在不同，但是右侧颞上回也不存在于两组的功能连接网络里，如何解释右侧颞上回的连接下降呢？谢谢各位老师。

  • 请教：任务状态下的功能连接
    Fri, 02/01/2013 - 13:09junperson
    尊敬的老师，您好！ 我想请教您的是任务态的数据（如blocked design, event-related design）可否拿出来做功能连接？ 比方说：用任务激活的区域作为种子点对全脑进行功能连接计算。 如果可以需要注意哪些问题（与静息态功能连接不同的地方）？ 比方说：1.对信号频段的提取（filter）还是0.01~0.08Hz吗？  2.任务态的每个run如果只有5分钟，是不是太短了？  3.如果每个run太短的话，是否可以直接讲几个run的数据放在一个文件夹里进行计算（...
