 # Designating electrophysiology data
 # ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-#
 # As mentioned above, :py:class:`~pynwb.ecephys.ElectricalSeries` objects
 # are meant for storing specific types of extracellular recordings. In addition to this
 # :py:class:`~pynwb.base.TimeSeries` class, NWB provides some :ref:`modules_overview`
 # for designating the type of data you are storing. We will briefly discuss them here, and refer the reader to
 # :py:mod:`API documentation <pynwb.ecephys>` and :ref:`basics` for more details on
 # using these objects.
 #
-# For storing unsorted spiking data, there are two options. Which one you choose depends on what data you 
-# have available. If you need to store the complete, continuous raw voltage traces, you should store the traces with
-# :py:class:`~pynwb.ecephys.ElectricalSeries` objects as :ref:`acquisition <basic_timeseries>` data, and use
-# the :py:class:`~pynwb.ecephys.EventDetection` class for identifying the spike events in your raw traces.
-# If you do not want to store the raw voltage traces and only the waveform 'snippets' surrounding spike events,
-# you should use :py:class:`~pynwb.ecephys.SpikeEventSeries` objects.
-#
 # The results of spike sorting (or clustering) should be stored in the top-level :py:class:`~pynwb.misc.Units` table.
 # The :py:class:`~pynwb.misc.Units` table can contain simply the spike times of sorted units, or you can also include 
 # individual and mean waveform information in some of the optional, predefined :py:class:`~pynwb.misc.Units` table
