ECG/EOG/EMG biosignals recording

Fig 1. Montage creation All stanadrd Mitsar-EEG amplifiers have extra bipolar channels for extra biosignals recording. Following data can be acquired: Electrocardiogram (ECG or EKG)Electrooculogram (EOG)Electromiogram (EMG)RespirationAnd etc. Below is the scheme of electrodes placement of the subject body or face to record proper signal. It is also required to add POLY (BIO) channel to the montage like shown on the EEGStudio screen capture on Fig 1.Be aware that signal amplitude of EEG and biosignals could be different and it might be [...]

Dry sensors for SmartBCI wireless EEG

Dry cap top view SmartBCI wireless EEG systems now support both standard wet electrodes and caps with dry sensors. We have upgraded the EEG amplifier and design special EEG cap with active electrodes with soft dry sensors. Now all SmartBCI system are compatible with both types of electrodes without any modification. You can now order extra 21 channel dry cap for your SmartBCI system in addition to your clinical kit with wet electrodes. Dry EEG cap includes 19 EEG channels [...]

Short-Delay Neurofeedback Facilitates Training of the Parietal Alpha Rhythm

Figure 10: The magnitude of sustained changes in alpha rhythm parameters as a function of actual mean feedback latency for A) alpha magnitude, B)burst incidence rate, C) burst amplitude and D) burst duration. The text on each panel shows p-value for the hypothesis that the correlation coefficient is zero obtained with the parametric t-test and with a randomization test (in brackets). Only gain in alpha-spindles appear to have a significant linear dependence on feedback latency. Our great collaborators from Center [...]

ADHD and Neurofeedback training

The use of Neurofeedback for Attention Deficit Hyperactivity Disorder. Attention Deficit Hyperactivity Disorder (ADHD) is a big social problem as a lot of children have it. The origin of ADHD is genetic mechanisms, organic brain damage, and psychosocial factors. Children and adolescents suffering from ADHD are characterized by restlessness, distraction, hyperactivity, impulsivity, poor school performance, fatigue. These symptoms may be the result of reduction of activation level of frontal cortex in combination with dysfunction of non-specific trunk structures and midbrain. An integrated approach to the diagnosis [...]

EEG caps overview and comparison

Our Mitsar-EEG amplifiers are compatible with a few EEG caps. Mitsar-EEG-BT and Mitsar-EEG-202-24 are equipped with D-sub DB25 connector that is used in most EEG caps on the market. Mitsar-EEG-202-31 require either custom EEG caps with D-sub DB37 or it could be used with regular caps via adapter that could be ordered together with a EEG system. Below we have listed 3 different EEG caps with electrodes placement according to the international “10-20” system that are compatible with Mitsar-EEG systems. [...]
