 ## Usage
 
-The `BinnedAlignedSpikes` object is designed to store counts of spikes around a set of events (e.g. stimuli or behavioral events such as licks). The events are characterized by their timestamps and a bin data structure is used to store the spike events around each of the event timestamps. The `BinnedAlignedSpikes` keeps a separate count for each of the units (e.g. neurons).

 ### Parameters and data structure
 The structure of the bins are characterized with the following parameters:
  
-* `milliseconds_from_event_to_first_bin`: The time in milliseconds from the event to the first bin. A negative values indicates that the first bin is before the event whereas a positive value indicates that the first bin is after the event. 
+* `milliseconds_from_event_to_first_bin`: The time in milliseconds from the event to the first bin. A negative value indicates that the first bin is before the event whereas a positive value indicates that the first bin is after the event. 
 * `bin_width_in_milliseconds`: The width of each bin in milliseconds.
