  :mod:`neo.core` provides classes for storing common electrophysiological data
  types.  Some of these classes contain raw data, such as spike trains or
  analog signals, while others are containers to organize other classes
  (including both data classes and other container classes).
  
  Classes from :mod:`neo.io` return nested data structures containing one
  or more class from this module.
  
  Classes:
  
  .. autoclass:: Block
  .. autoclass:: Segment
  .. autoclass:: Group
  
  .. autoclass:: AnalogSignal
  .. autoclass:: IrregularlySampledSignal
  
  .. autoclass:: ChannelView
  
  .. autoclass:: Event
  .. autoclass:: Epoch
  
  .. autoclass:: SpikeTrain
  .. autoclass:: ImageSequence
  
  .. autoclass:: RectangularRegionOfInterest
  .. autoclass:: CircularRegionOfInterest
  .. autoclass:: PolygonRegionOfInterest
  
  Deprecated classes:
  
  .. autoclass:: ChannelIndex
  .. autoclass:: Unit
