Add Comment
The Add Comment feature allows the user to add a timestamped text comment to the
Neural Event file. Comments can be visualized in the Raster Plot view. When in the
Raster Plot window or the Central Main Window, a comment time stamp is initiated by
typing and completed when the <Enter> key is pressed.
nPlay Server
nPlay Server loads and replays recorded neural
data in ‘.nsx’ or ‘.nev’ formats for viewing and
analysis in Central. When playing back the
continuous data files, the user can filter, sort
spikes, and down sample. A Neural Signal
Processor does not need to be connected to the
PC to use this utility.
