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 […]
EEG is one of the biological potentials with lowest amplitude (typically a few microvolts). It is highly sensitive and is likely to be contaminated by undesired non cerebral potentials coming from biological or external sources. These unwanted signals dirtying your recording are called artifacts. Even though there are more, through this post I will try […]
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 […]
At Neuroelectrics and Starlab we intend to stimulate activity in the areas we work in and we are convinced that one of the ways of achieving this is by publicly sharing our knowledge on different topics we find interesting. Following this philosophy, more than a year ago we started the blog you are now reading, […]
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 […]
Researchers working on the field of Neuroscience have surely sometimes thought about this question. It might sound like Sci-Fi for the common laymen, but neuro-implants are a reality nowadays. In this post I would like to give an introduction to the different brain recording techniques and comment the pros and cons of invasive vs. non-invasive […]
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 […]
Carrying out an EEG experiment is complex, expensive and time-consuming. This blog post is meant to provide a series of guidelines by focusing on a concrete experiment. Hopefully this will teach you some basic concepts regarding experimental design in general and it might also save you some time and money by not falling into typical […]
Recording a EEG signal can be tricky. Many conditions, internal and external, can affect the signal that you want to obtain. The quality of the sensor, the correct placement of the electrodes, the appearance of interferences, or many other issues can modify the fidelity of the signal you finally record. In his last post, Dr. […]
