Why are beta waves split into low beta and high beta in EmotivPRO, while others are not?

Most brainwave bands—like delta, theta, and alpha—are typically defined in relatively narrow frequency ranges, often about 4 Hz wide. However, the beta band spans a much broader range of frequencies, which is why we’ve chosen to divide it into low beta and high beta.

This split allows for more precise discrimination between different types of mental activity. For example:

• Low beta is generally associated with less demanding cognitive tasks—such as alertness, focus, or mild concentration.
• High beta, on the other hand, is linked to more intensive cognitive processing, such as problem-solving, decision-making, or activities that require more brain networks and resources.
  

By separating the beta band, we can gain finer resolution in interpreting brain activity, especially in research or performance-related contexts. It’s important to note that this split doesn’t result in any loss of information—the low and high beta bands can easily be recombined if needed.

As for gamma waves, although they also occupy a higher frequency range beyond beta, they represent a distinct class. Gamma is generally involved in high-level processing, such as memory recall, learning, and the integration of information across brain regions. In short, Beta is split simply because it covers a wider frequency range, and dividing it provides more analytical value without compromising the integrity of the data. It’s easy to recombine the low and high beta ranges, so there is no information lost.
