Recording brain waves in extreme situations: The psychoactivity of ayahuasca

This user research summary is based on the article “Acute Biphasic Effects of Ayahuasca“. Ayahuasca is an amerindian psychoactive sacrament used worldwide. Neuroscience studies have shown contradictory results regarding its effects in the brain. Combining EEG, plasma samples and robust statistics, we’ve uncovered biphasic effects in the brain which are related to many psychoactive compounds, not only N,N-dimethyltryptamine (DMT), as previously proposed.

  • Decoding subjective taste categories using multivariate pattern analysis of single-trial EEG

Decoding subjective taste categories using multivariate pattern analysis of single-trial EEG

Compared to other senses, very little is known about taste. In a recent study (Crouzet, S. M., Busch, N. A., & Ohla, K. (2015). Taste quality decoding parallels taste sensations. Current Biology, 25(7), 890-896.), we used mulitvariate pattern analysis of single-trial EEG data to investigate which information about a taste is represented in taste-evoked brain responses.

New CapTrak software version 1.1.0 supports actiCHamp systems

Brain Products is happy to announce a new version of the CapTrak electrode localization system (to be released in mid-April 2015), which interfaces directly with one of our company’s flagships: the actiCHamp EEG recording system. The new CapTrak software allows not only to localize the electrode positions in an extremely easy, accurate and fast way. It also helps to figure out if the cap has been misplaced in consequent measurements or if the cap size does not fit your subject!

actiCHamp revision 3.0 now with clock output for synchronization with tAC, tDC and tRN stimulators

Removing artifacts induced by tDC, tAC, tRN stimulators from EEG signals is a tricky and challenging task. However, it is a key prerequisite for EEG signal analysis. Artifact-corrected EEG data will lead to improved scientific conclusions on the effects of the stimulation that has been applied.

Recording EOG signals with actiCHamp – active or passive electrodes?

The artifacts produced by eye movements and blinks are problematic for the EEG researcher and can have a negative impact on results. Advanced algorithms (e.g. Ocular Correction ICA) can be very effective in correcting the ocular related artifacts, however in some cases a dedicated ocular channel is required. Here, we will describe various approaches on how to use an actiCHamp amplifier to record an Electrooculogram (EOG).

Product Launch: Photo Sensor

The Photo Sensor measures the screen brightness and, when combined with StimTrak, generates a trigger at the exact stimulus onset. It is a valuable tool to check the performance of a monitor or any experiment control software. This becomes essential if visual stimuli are planned to be presented on a tablet or cell phone display.
