Events, Intervals – Multichannel Systems NeuroExplorer User Manual
Page 42
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
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
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
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
for details).
Each interval variable can contain multiple time intervals. For example, the Frame variable in the
following figure has two intervals:
