Holding information in working memory is essential for cognition, but removing unwanted thoughts is equally important. Here we use multivariate pattern analyses of brain activity to demonstrate the successful manipulation and removal of information from working memory using different strategies including suppressing a specific thought, replacing a thought with a different one, and clearing the mind of all thought. These strategies are supported by distinct brain regions and have differential consequences for allowing new information to be encoded.

在工作记忆中保持信息对于认知至关重要，但去除不需要的想法同样重要。在这里，我们使用大脑活动的多元模式分析来证明可以使用不同策略成功地操作和去除工作记忆中的信息，这些策略包括抑制特定的想法、用不同的想法替换一个想法以及清空头脑中的所有想法。这些策略得到了不同脑区的支持，并对允许新信息编码产生不同的影响。
