Can I record high-density sEMG with the ActiveTwo system?
High density surface EMG as described in the recent publications on the Biosemi site is possible with the addition of the sEMG accessories. The original model of the high density sEMG probe was made for ActiveOne, so the connector differed. The current version separates the electrode grid from the preamp as in: reusable grid sEMG preamplifier…
Read MoreHow long do active electrodes last, and what is the process for repair if they get broken?
We expect the new red-rubber reinforced ActiveTwo active electrodes to last more than 1000 uses, based on our experience so far, and based on automated repeated-strain testing. The way ActiveTwo electrode sets are built, they are not repairable by the end-user, but we can replace single electrodes for you. We can so this quickly (24…
Read MoreCan I install ActiView on a Windows 10 computer?
You CAN install current versions of ActiView on Windows 10. But, before you do so, if the system was orignally delivered before January of 2017 you should update the firmware on the optical receiver / USB interface so that you do not have to go through the very long and arduous process of installing an…
Read MoreWhere can I find the coordinates of the 128 channel caps based on the 5% system defined by Oostenveld and Praamstra?
The positions in these caps come from the Oostenveld and Praamstra 5% system. See http://robertoostenveld.nl/electrode/ for background and for links to electrode coordinates in a variety of formats. Depending on what software you are using for analysis, we might be able to provide another file format. The Biosemi channel assignments (relating electrode labels to electrode sites in…
Read MoreWhat are the computer requirements for ActiveTwo?
ActiveTwo is provided with drivers and host data acquisition software for Windows, Mac, and Linux computers. Note that certain applications, such as event-related potentials, often require a separate computer to run experimental control / stimulus delivery software. The requirement for a separate computer for stimulus delivery is more a function of the experimental control software…
Read MoreWhat is the purpose of amplifier/converter modules in the ActiveTwo system?
The ActiveTwo Base System has no channels. The Base System consists of the parts that every ActiveTwo system needs to have, but excludes the parts that are used to custom configure ActiveTwo for various purposes, like amplifier/converter (AC modules). The AC modules give the system the capacity to record from active electrodes. With four of…
Read MoreIs every TMS system EEG compatible?
Maybe. There is no way the EEG system can harm the TMS system, but there are some TMS systems that are essentially useless with some EEG systems. You need a a suitable combination of features in each to be successful at all in using TMS with EEG. Desirable attributes: Coils designed specifically for use with…
Read MoreIs every EEG system TMS compatible?
No. There are a few special attributes that are required and others that are desirable. Required attributes: Inputs should be protected so that they are not damaged by the TMS pulse Frequency response on all channels should be from DC on the low end, since AC coupled inputs will “ring” when presented with a large…
Read MoreWhat is the difference between 1020 and ABC electrode / cap labels?
Electrodes and head caps can have positions derived from systems based on the International 1020 System. When the positions are based on 1020, the labels on the caps and electrodes can either be the actual 1020 position names (such as Fp1, Cz, etc) or they can be what is called ABC, which actually means A1,…
