Brain-to-brain communication

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. […]

Measuring the effect of meditation using EEG

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 […]

EEG features

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 […]

Single-Channel EEG

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 […]

Artifacts Contaminating Your EEG Recordings

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 […]

tDCS clinical research – recent highlights: Pain

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 […]

Audio neurofeedback

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 […]

What is Loreta? What can I use it 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 […]

A Simple EEG Experiment

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 […]

6 Ways to EEG Gold

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. […]
