1 vs 2 ch with the BioGraph Infiniti Suite for TLC Assessment

March 28, 2008

Good clarification Jill, I was just going to point to this.

If you don't connect anything in one input (like C or D, with the ProComp

Infiniti encoder), you won't get anything from that input. And when you

review your session, you will have graphs and data only for the side with

attached EEG sensor and electrodes.

This is true of all screens in the BioGraph Infiniti Suite for TLC

Assessment and Training. For example, if you want a one channel

Windowed-Squash, just connect one set of electrode and use the C+D

Windowed-Squash screen.

Because of the way the report screens are created, it make sense to use

input C with elecrode on the left or frontal part of the head and to use

input D with electrode on the right or posterior part of the brain.

The new training suite (The Integrated Neurofeedback) will have more

options: Screens with one channel only, like " C " ; screens with one channel

being the focus of training but with a second channel connected for artefact

monitoring on both sides, like " C(D) " ; and 2 channels, like " C+D " .

See attahment for more info.
