Some would say that my mom is a bit eccentric … When we were little, she would have us play a fun game … well, I remember this happening at least once probably around 1975. The game was … telepathy. My siblings and I would sit around for a while trying to transmit each other thoughts. […]
While heading to Petronas Technology University where I will give a course on transcranial current stimulation (tCS) basics I summarized the basics of the technology and particularly on Starstim, the device we envisioned and started to develop within the HIVE project. tCS devices allow the controlled injection of low-amplitude electrical currents into the cerebral cortex […]
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. […]
In a previous post, I explained the basic steps in EEG data analysis. Now I will go trough the type of EEG featuresmost commonly used inEEG applications. First of all, we have to understand that an EEG signal is a discrete time series (or a set of discrete time series if we consider more than […]
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, […]
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 […]
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 […]
Neuro-imagining techniques aim to represent the structure or functioning of the brain. They can be understood as an X-ray photograph of the brain that in the case of functional imagining will show the brain areas activated during a process or cognitive task, and techniques such as fMRI, PET or MEG are examples. Pascual-Marqui, Michel and […]
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 […]
If you have ever worked in the field of biopotential recording, you surely are aware of the omnipresent artefacts. If you haven’t, let me introduce you to them. Artefacts includes all the parts of your recorded signal that does not originate from the source you are expecting the signal to come from. That is the […]
