Trends in tDCS at SfN 2014

This year at SfN we had 20 posters and 2 nano-symposia featuring tDCS in the title from a similar number of labs. On the face of it this is very good for the field that so many labs are exploring the technology but I think it’s interesting that only 3 directly address the parameters of […]

SSVEP-Based Brain Conputer Interfaces

As I explained in one of my previous posts, a Brain Computer Interface (BCI) is a direct communication pathway connecting the brain to a computer or other external device. BCIs do not depend on the brain’s normal action pathways through peripheral nerves and muscles. This makes them the ideal technology to develop systems assisting or […]

Modern History of Neuroscience

A few months ago I wrote “The Unknown History of Brain Science” in which I briefly covered the evolution of Neuroscience up to the discovery of the EEG by Hans Berger in 1929. Much more has happened since. Let’s see the most break-through discoveries that happened in this last 100 years or so. In my […]

Are brains computers?

Recently Stephen Hawking apparently said “I think the brain is like a programme in the mind, which is like a computer, so it’s theoretically possible to copy the brain onto a computer and so provide a form of life after death.”, which understandably generated a fair amount of noise on Twitter and elsewhere. I think […]

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 […]

EEG in multimodal environments

We have been working lately on some applications that take EEG sensors out of the common lab and put them out in the cold, through applications that use EEG in multimodal environments, like virtual reality worlds, augmented reality set ups, sport training systems, etc. This brings a lot of new approaches, usages and opportunities to the EEG […]

What is QEEG?

Non-invasive EEG recording techniques consist of the recording and interpretation of voltage fluctuations generated by the brain along the scalp, being measured by an array of electrodes that covers the whole scalp surface or a given area of interest. From the first EEG experiment recorded by Berger in 1929 to the late 1960’s EEG was […]

The Unknown History of Brain Science

Brain Science is older than you might expect. Of course, many of the first brain theories were wrong, but you might be surprised by the fact that the first known writings about the brain date fback to 4000 BC. Let’s have a quick overview of some of the main historical milestones regarding the Unknown History […]

How To Understand The Machine Learning Family

In former posts I have given a quick-and-dirty overview of Machine Learning and related methodologies: “what most people call machine learning in neuroscience academic texts is known in other research contexts as pattern recognition, data mining, artificial intelligence (AI), computational intelligence (CI), soft computing (SC), or data analytics. All of these refer to more or […]
