SubliminalHomerehab cover image
SubliminalHomeRehab is a Eureka Eurostars project aimed at developing and validating an upper-limb motor rehabilitation system for stroke patients. This project, led by Bitbrain, is  developing a home-based neurorehabilitation platform to be setup and used autonomously by the patients alone. This system combines measurements of brain electrical activity (electroencephalography, EEG) and kinematics (inertial measurement units, IMUs) to control electrical stimulation of the paralyzed arm muscles.

girl wih preparing for a sleep EEG test
Sleep is a natural behavior that forms part of our daily routine. It can be found in virtually the entire animal kingdom and plays a fundamental role in people's well-being. During sleep, a significant number of brain and body functions remain active for restorative purposes. Without enough sleep, the homeostasis of the sleep-wake cycle is seriously compromised, which can result in a number of disorders directly affecting cognitive performance and physical health.

According to UNESCO, less than 30% of people conducting scientific research in the world are women, only 3% of Nobel prizes in science have been awarded to women, and only 11% * positions in senior research are held by women in Europe. On the other hand, in the technology sector, women only represent 17.5% of the technology workforce worldwide (Honeypot, 2018) and occupy 5% of leadership positions (PWC, 2017).

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.

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.

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.

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.

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/neuromarketing, 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. While there are still some limitations

eeg data processing with ai, deeplearning, machine learning
EEG systems capture information about many different aspects of our cognition, behavior, and emotions. The technology not only helps to study the brain, but also has applications in health, in affective and emotional EEG monitoring, and in human improvement. However, EEG data is not easy to interpret: it has a lot of noise, varies significantly between individuals and, even for the same person, changes substantially over time.

a participant performing an implicit bias test
Implicit measures became very popular years ago by the academics, and many researchers employed them to analyze biases in racial groups, gender, sexuality, age, and religion, as well as to assess self-esteem in clinical psychology. Today, other applications in market research have emerged to gather information on implicit preferences of products, brands, politicians, and celebrities, and to reveal which attributes are more inherently associated with these concepts.

slider eeg amplifier tech features
When choosing an electroencephalogram (EEG) device within the constraints of a project requirements, it is important to find the maximum performance possible by balancing features and value. This article will build on top of the previous one (EEG sensor layer) by addressing important EEG amplifier features like sampling rate, bandwidth, noise level, CMRR, etc.
