描述----------Description----------
The 'paulsen' data frame has 346 rows and 1 columns.
“保尔森的数据框有346行1列。
Sections were prepared from the brain of adult guinea pigs. Spontaneous currents that flowed into individual brain cells were then recorded and the peak amplitude of each current measured. The aim of the experiment was to see if the current flow was quantal in nature (i.e. that it is not a single burst but instead is built up of many smaller bursts of current). If the current was indeed quantal then it would be expected that the distribution of the current amplitude would be multimodal with modes at regular intervals. The modes would be expected to decrease in magnitude for higher current amplitudes.
切片制备从成年豚鼠大脑。自发性电流流入个别脑单元，然后记录和测量每个电流的峰值幅度。实验的目的是看到如果量子性质（即，它不是一个单脉冲串，而是建立许多更小的脉冲串的电流）的电流流动。如果当前的确是量子然后将期望的电流振幅的分布将是多峰与以规则的时间间隔模式。将期望的模式，以降低较高的电流振幅的大小。
