How to decide which EEG amplifier best fits your research

You would like to start with EEG research, but you are unsure what amplifier works best for you? Given the range of possibilities, it can be hard to choose the best EEG amplifier for your research. If you could use some guidance, this article is a good start for you!

  • EEG amplifier signal pipeline, and why you (mostly) do not need to worry about aliasing

EEG amplifier signal pipeline, and why you (mostly) do not need to worry about aliasing

An EEG signal goes through various transformations on both the hardware- and software-level before being saved on the hard disk or being displayed on the screen. This article explains the pipeline principles and highlights the difference between user-configurable filters vs. automatic filters that prevent aliasing artifacts by design.

  • Mains Power Supply for BrainAmp amplifiers is now available!

Mains Power Supply for BrainAmp amplifiers is now available!

The best possible data quality is achieved by using a battery to power your EEG amplifier. However, there are many cases where a mains power supply is needed to ensure uptime of the system in your lab. With Mains Power Supply for BrainAmp we reintroduce a solution that allows you to power BrainAmp amplifiers from the mains.

  • A guide to peripheral physiology measurements using the Brain Amp ExG MR – Part 2: Let’s focus on ECG

A guide to peripheral physiology measurements using the BrainAmp ExG MR – Part 2: Let’s focus on ECG

In this part of our peripheral physiology series we introduce ECG measurement using BrainAmp ExG MR in the MR environment. The safety issues associated with ECG in the MR environment are highlighted. We explain the mechanisms which may limit the signal quality and introduce a methodology to obtain precise heart rate information.

Keeping active electrodes fit and well: A guide for diagnosis and repair

Are you a user of the Brain Products active electrodes? Do you struggle to check whether your active electrodes are still fit for recording? Was it already suggested to perform a “saline test” but you are not sure on how to interpret the outcome of your test? This article might be ideal for you!

  • EIB64-DUO – a common input box for both actiCHamp Plus and BrainAmps

EIB64-DUO – a common input box for both actiCHamp Plus and BrainAmps

You might have already come across an Electrode Input Box (EIB). In the past, the main function of the EIB was to enable the use of touch-proof (1.5 mm DIN) electrodes with either BrainAmp or actiCHamp Plus systems. If your lab already has both actiCHamp Plus and BrainAmp equipment, you might find the new EIB64-DUO from Easycap particularly interesting for your passive electrode setup!

  • Transcranial Evoked Potentials can be reliably recorded with active electrodes (Fig. 1)

Transcranial Evoked Potentials can be reliably recorded with active electrodes

In this article, based on our current work, we compared transcranial evoked potentials recorded with active and passive electrodes. Signals obtained with the two methods did not statistically differ in amplitude and topography, and showed a high degree of similarity across the scalp. We conclude that active electrodes are a viable solution for studies combining transcranial magnetic stimulation and electroencephalography.

A guide to peripheral physiology measurements using the BrainAmp ExG MR – Part 1: Let’s focus on EMG

Using the BrainAmp ExG MR to record peripheral physiology in the scanner can add another level of measurement to your studies. If you want to learn more about performing safe and successful EMG measurements in the MR environment, this article is for you.

  • How to do hyperscanning with BrainAmps

Hyperscanning series part 1: How to do hyperscanning with BrainAmps

This first part of the hyperscanning series introduces our current gold standard hardware solution for this application: the BrainAmps. Combining multiple BrainAmps allows using separate ground and reference channels for each participant and provides perfect clock synchronization in a single EEG recording file.
