Numerical values of the timestamps (in seconds) are shown in the Timestamps sheet of the Data

view:

2.1.2. Events

Event data type in NeuroExplorer is used to represent the series of timestamps recorded from

external devices (for example, stimulation times recorded as pulses produced by the stimulus

generator). Event data type stores only the times when the external events occurred. A special

Marker data type is used to store the timestamps together with other stimulus or trial information.

Events are very similar to spike trains. The only difference between spike trains and events is that

spike trains may contain additional information about recording sites, electrode numbers, etc.

Internally, event timestamps are represented exactly as Spike Train timestamps. See Spike Trains for

more information about the timestamps in NeuroExplorer.

Creating Event Variables

You can add events to the data file using Copy | Paste command in the Timestamps view (see

Importing Data from Spreadsheets for details).

You can also create additional events based on the events in the data file. Use Edit | Operations on

Data Variables menu command and then select one of the operations in the Operations dialog.

2.1.3. Intervals

Intervals are usually used in NeuroExplorer to select the data from a specified time periods (see Data

Selection Options for details).

Each interval variable can contain multiple time intervals. For example, the Frame variable in the

following figure has two intervals:
