       y: The current flowing into individual brain cells.
          The currents are measured in pico-amperes.

     The `paulsen' data frame has 346 rows and 1 columns.

     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.
