N-Trode
Multiple single channels can be linked into N-Trode channel groupings. These are user
defined electrode subsets created to record signals from proximal regions when any
single unit spike is detected within the N-Trode. N-Trodes allow for neural events
detected on one channel within an N-Trode to force the creation of neural events on the
other N-Trode channels. When an event is detected on a channel within an N-Trode, all
other N-Trode channels record a neural event with the same timestamp, spike width
samples, pre-threshold samples, and refractory period (see Global Settings). Central
supports multiple N-Trode sets containing up to four electrodes each. Define N-Trode
configurations in the Hardware Configuration window or within the N-Trode application
window.
Note:
Spike sorting occurs on the N-Trode as a single entity. This causes neural events
on all N-Trode channels to be subject to refractory periods caused by a neural event
detected on any N-Trode channel.
