Solving BCI bottlenecks for medical applications

Medical BCI-based applications are still limited. Neuroelectrics is addressing most critical issues so that they can be effectively adopted in clinical settings or in users’ homes. Carabalona et al. (2009) discussed several points that need to be considered when designing, selecting and using a BCI system for neurorehabilitation purposes. In particular, they emphasized the importance […]

Out-of-Body-Experiences and Neurosciences

“The easiest path is not always the best” Lobsang Rampa, The Third Eye  Ever since I read when I was a teenager Lobsang Rampa’s The Third Eye, I have been fascinated with astral traveling, or as modern science calls it, Out-of-Body Experiences (OBE). In the last years, OBE have been studied from a neuro-scientific point […]

Can cortical networks be used to analyse EEG signals?

Broadly speaking, when we talk about analysing EEG signals, we are talking about how to use those time-varying signals to classify clinical conditions, behavioural events or predict responses (is the person awake or not? is this person going to develop Parkinson?). As such, learning temporal dependencies in those time series and predicting or classifying events […]

SONAR – BRAINPOLYPHONY

Since its first edition in 1994 Sonar Festival is definitely one of the electronic music festivals you cannot miss. For its sixth consecutive year in Barcelona, Sonar+D organized its famous hackathon along with the Music Technology Group of the Universitat Pompeu Fabra. Sonar Music Hack Day (MHD) is a hacking session in which participants will […]

Moving Neuroscience out of the lab

Recently in Starlab we conducted some recordings out of the lab. We equipped some volunteers with a bunch of EEG, ECG and GSR sensors along with a GoPro cam so we could capture electro-physiological signals as well as volunteers’ point of view during the whole experiment. The idea was to record people while visiting an […]

BCI Evolution-Exploring Opportunities

Brain-Computer Interaction (BCI) based technology is thriving and has the potential of spreading into society by addressing the needs of various user groups under different application scenarios. Wolpaw and Wolpaw (2012) identified the five principal BCI scenarios or application types that may have evolved so far, namely, replace, restore, improve, supplement and enhance. Communication is […]

Support Vector Machines: What they do and their best ‘trick’

In the past years machine learning has been used to address many different problems in neuroscience. When we talk about classification, several algorithms have been proposed for specific tasks. For instance, in Starlab we have used discriminative learning algorithms for EEG/ECG classification (e.g. neurodegenerative diseases) or time-series classification. This type of algorithms model the dependence […]

Get your brain fit

As I have explained in a previous post, we loose about 100 000 neurons per day. But this is not something to be really worried about, since the thing that really matters is the quality of their connections, not their number. As we know, the brain is plastic so we can create new connections and […]

Music from the brain: a new way of communication for patients with severe speech disabilities.

In this post I would like to introduce the concept of BrainPolyphony, a CRG Awards-founded project in which  Centre de Regulació Genòmica (CRG), Universitat de Barcelona, Mobilitylab, ASDI and Starlab will explore new ways of communication for patients suffering from severe speech disabilities. Patients with neurodegenerative diseases, such as cerebral palsy, often experience important communication problems. […]
