During the next weeks in Starlab/Neuroelectrics we will conduct a study on meditation patterns measured in EEG brain signals. First of all, I would say that previously I had no idea about what mediation was, I have never practiced yoga or any other meditation technique, and obviously I am far from being an expert in […]
As I have mentioned some times in previous posts, I am pretty sure that in the next years we will see great advances in the field of neuroscience. The 20th century was the century of physics, with great discoveries such as the theory of relativity and quantum physics, among others. I reckon the 21st century […]
On 11th November 2012, I successfully defended my PhD at the University of Barcelona. I will never forget that date and I still vividly remember all the emotions I felt that day. After 5 years of intense research, I had 45 minutes to brief the jury about the motivation, methods and results of my research. […]
One of the holy grails of EEG, along with dry electrodes, is the idea of single-channel EEG. Or rather, useful single-channel EEG. It’s very easy to record EEG from a single channel but making sense of the data and building a useful application around it is not. The reason that single-channel EEG is so attractive […]
Some time ago we carried out an experiment in Starlab to see if we could find stress markers in EEG signals. This research was done within the Interstress European project. The positive results of this experiment were also used as a part of my PhD thesis. I will briefly explain in this post the experiment […]
As most of you may know P300 is one of the most studied and used event related potentials (ERP) in brain computer interfaces (BCI). This potential is usually elicited by the oddball paradigm in which series of low-probability target items are mixed with high-probability non-target ones. The person carrying out the BCI task is asked […]
Is transcranial current stimulation (tCS, including direct current, tDCS, alternating current, tACS, or random noise stimulation tRNS) effective? Now that is a good and difficult question! Let me try to review recent developments. In a recent post I provided an overview of tCS in Stroke. Here I do the same but for Pain. Please let […]
To celebrate my 14th post in Neuroelectrics blog, I have decided to share 14 different ERP components and modalities with you. I presume you know a bit about ERP’s, or else please have a look at the basic ERP concepts explained in my previous post “Event-Related Potential: Our Brain Response To External Stimuli” before going […]
Today, instead of writing about something I’ve worked on or something I know, I want to do something different: I want to learn about something together with you, the readers. There’s a particular application which I don’t know much about, and I’d like to learn or read about it. And I thought that writing here […]
With our previous posts, we have been trying to provide our readers with a complete set of knowledge and tools for working with EEG and other physiological signals. We presented the basics of EEG signal processing, the practical usage of EEG signal processing related to emotions or Alzheimer, useful technologies like machine learning, practical guidelines for […]
