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. […]
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 […]
When you think about biometrics, futuristic movies like Minority Report or Gattaca might come to your mind. However, the use of biometrics for authentication purposes has been around for a long time but mostly after the 9/11 terrorist attacks. After that event the identification of citizens and travellers has become a priority on the international agenda and […]
EU-funded project AsTeRICS was born with the main objective of developing a support platform to facilitate and improve communication resources of people with motor disabilities, with no cognitive impairment, no perceptual limitations (neither visual nor auditory) and with basic skills in using technologies such as PCs, cell phones, electronic agendas, etc. For most potential users […]
As promised in my previous post about Event-Related Potentials, I will explain the basics and standard steps commonly used in the analysis of EEG signals. There is a lot of literature and many concepts are involved in the field of EEG signal processing, and some of them can get very technical and difficult. That is […]
If you are interested in Neuroscience, I am sure you have heard the term event-related potential. My objective in this post is to provide you with an introduction to this widely used neuroscience technique. In order to do so, let me first categorise EEG recordings in two groups: Spontaneous EEG: the subject can have his/her […]
By following these tips, you will ensure a good experiment, avoid major problems and in the long term save a lot of precious time. Be sure you follow them very carefully if you want to have good quality and useful EEG data! 1) Understand very well what you want to study and why …and if […]
