In 2003, Giulio Tononi and Chiara Cirelli, biologists at the University of Wisconsin-Madison, proposed that synapses grew so exuberantly during the day that our brain circuits got "noisy." When we sleep, the scientists argued, our brains pare back the connections to lift the signal over the noise.

2003年，威斯康星大学麦迪逊分校的生物学家朱利奥·托诺尼（Giulio Tononi）和基娅拉·奇雷利（Chiara Cirelli）提出，突触在白天生长得非常激烈，令大脑电路变得“嘈杂”。当我们睡觉时，大脑得以减少连接，这样真正的信号才可以超过噪声。
