EEG neurofeedback technology
Strictly speaking, the term alpha brain waves refers to neural oscillations in the range of 8 to 12 hertz. In many instances, however, the term connotes much more than a particular waveform. Through a combination of scientific and cultural factors, alpha has come to signify relaxation, tranquility, and even spirituality. Below, we offer a brief history of alpha waves, with the goal of contextualizing modern interpretations of the rhythm.

neurorehabilitation EEG device
Neurorehabilitation and assistive technologies use brain-computer interfaces (BCIs) to involve the central nervous system in the rehabilitation process or to allow control of technology. Moving BCI-based neurorehabilitation or motor restoration applications from the laboratory to home settings will improve accessibility to therapies and assistive applications. This will increase potential benefits and allow a more intensive data collection to foster scientific progress.

girl that fainted beacuse of an epilepsy seizure
Epilepsy is a chronic neurological disorder that affects about 50 million people worldwide. The most visible symptom is the appearance of seizures, an abnormal electrical signal that occurs inside the brain. The electroencephalogram (EEG) is a non-invasive brain recording technique that detects seizures accurately. In this post, we will show you the characteristics of the signals associated with seizures and the procedures used in the diagnosis of epilepsy.

tech features of EEG systems
One of the key aspects to consider when we plan to start an EEG-neurotechnology project is the hardware. There are several technical specifications and parameters that should be considered when choosing a system that best adapts to our project requirements. In this post, we will help you understand the main features of an electroencephalogram (EEG) system.

Woman wearing a wet eeg cap
A Wet-EEG cap is a type of electroencephalogram (EEG) device that requires the use of an electrolytic substance to improve scalp-electrode conductivity. This term is used in opposition to dry-EEG. This post will help you understand the differences between those concepts and focus on the key points to be aware of when selecting a wet-EEG system.

EEG synchronization
One of the first questions to answer when we approach a research methodology that involves the recording of multiple devices is always: how do I synchronize the various signals? Due to the fact that there are many different systems and devices used by researchers that come from multiple vendors, or are developed by the researchers themselves, this is always one of the first problems to solve.

man wearing head-mounted eye tracking device
Recent advancements in eye tracking technology have expanded the field to include applications in many different areas, both as a tool for research and as a source of real-time data for interaction. Eye tracking has expanded well beyond the original research in vision and attention. As a result, the field now includes very disparate use cases. Systems are designed to fit certain applications and are often much less suited for others.

robotic hand extended
Electroencephalography (EEG)-based neurotechnology not only offers us new alternatives to interact with our environment directly via our brain, but also promises to improve our human functions. In this post, we will discuss how to exploit these technologies as a rehabilitative tool for people with nervous system damage, and how to facilitate human enhancement for the general population.

man and woman in iat
We are all somewhat biased due to our past experiences and the upbringing and education we have been given. It remains more or less unconscious in our minds, defining our beliefs, influencing our attitudes, and shaping our behavior. It is the reason why we associate the color black with elegance and red with passion. However, it is also the reason why technology is still more associated with boys than girls, or why, in part, we still suffer from racism.

indoor gps system in a store
Geolocalization is key to multiple applications and services. Indoor Positioning Systems (IPS) are key to extend these services indoors where GPS systems are not reliable. IPS are integrated and can be deployed in homes and buildings, and can interact with smart devices to provide them with spatial context. In this post we will explain how IPS work, what types of IPS technology exist, its features and its main applications to track people, from hospitals to market research.

old woman using modern neurofeedback for cognitive enhancement
Neurofeedback is a human enhancement technique aimed at providing cognitive improvements in psychological variables such as memory, attention, processing speed or executive functions. We describe herein neurofeedback and biofeedback techniques, the science behind one of the most validated protocols, the new trends in modern approaches, influenced by the advances in brain-computer interfaces, and some use cases and scientific results.

eeg connectivity layer
When choosing an electroencephalogram (EEG) device it is important to find the best possible performance by balancing device features and value. Once all the signal related features (those which apply to both sensor and amplifier stages) have been addressed, we will discuss other important characteristics such as connectivity, power, autonomy, data format, etc.

eye that is being recorded by an eye trracking technology
Eye tracking has become an invaluable tool for understanding attention, visual behavior and human behavior in a number of diverse fields, from psychology, neurophysiology, user experience, market research, etc. The technology can also be used for medical analysis and screening, and it provides a new method of interaction. Historically, eye tracking systems were invasive and immobile, and therefore useful only in very limited experiments.

girl wih a variable EEG electrode placement
The market for neurotechnology devices is growing, with many new tools available. Finding the right EEG headset can be a challenge. There are many features that will influence this decision, but a very important one is whether the EEG has a fixed or variable sensor layout. Variable layouts will give you flexibility at the cost of usability, and fixed layouts the opposite. We explain here the pros and cons of each version.
