Companies like NeuroSky and Muse promise neurofeedback solutions to help improve meditation and sleep, although the research potential of such devices is ultimately limited by this.Įmotiv offers 5 and 14 channel solutions, with built-in metrics to enhance understanding of the respondent’s mental state. The lower end of this list also, unsurprisingly, starts with the lowest amount of electrodes. Below you will find the price range of headsets from some of the leading manufacturers. Making a choice between devices is of course best done with an expert at hand, and we are always available if you want to discuss your needs. The specific prices can be hard to pin down, as some are not public, or can be subject to academic discounts, and can fluctuate with changing currency prices, amongst other reasons. This is why we have set out the range of prices you are likely to find when searching for the EEG headset that is perfectly suited to your needs. Part of the trade-off is that it takes longer to collect and analyze the data, but whatever your need are – it’s always good to talk to the experts first. Many of the devices at the upper ends of the pricing range are particularly advanced, research-grade devices that provide incredible sensitivity, with a large number of sensors too.

Each offers something unique for the consumer – whether it’s the number of channels, a stationary or portable device, the predefined metrics offered, or of course the price.Īs with many devices (and most things in life): you get what you pay for. This would mean that your computer would represent the data in the following way: Voltage 2- Bit Digital Representation 0-2.5 00 2.5-5.0 01 5.0-7.5 10 7.5-10.Electroencephalography (EEG) is a technique with over a hundred years of history, and while it was originally used more strictly in the fields of psychology, medicine, and neuroscience, it is widely used today in gaming, human-computer-interaction, neuromarketing, simulations, and beyond.ĭue to this increased use and demand of high-quality EEG devices, there are now numerous companies that are able to cater to the specific needs of EEG users. To give an idea of how it would work with eeg data, let’s say your system has 4 ADC bits and you want to measure a signal between 0 and 10 Volts. The number of bits is important in being able to accurately estimate the voltage, but more bits doesn’t necessarily mean better quality data. Simply put, the Analog to Digital Converter (ADC) Bits is the resolution of the signal. This EEG tutorials has some more details on the sampling rate ADC Bits: Depending on the frequency you are interested in studying, your sampling rate needs to be at least 2.5 times greater. Most devices will have a minimum of 256 samples a second, but you can find some which have a higher sampling rate. The Sampling Rate of an EEG is the number of sample a second you can get from your device. You would be better off with an OpenBCI so that you can place the electrodes where you want. If you want to measure Motor Imagery with the Muse, you won’t have much success. In most eeg papers, they will state where on the brain the strong response came from.Īlso, many consumer EEG’s have electrodes which are rigid and can’t be moved. Measuring Relaxation levels is easy with 1 or 2 electrodes but measuring other brain activity can be difficult. Number and Placement of Electrodes:ĭepending on the type of brain response you want to measure, your system may need a minimum number of electrodes. When deciding which EEG headset to purchase, there are a few features you should look at when making your decision.
