Patient Plays a Musical Instrument While Brain Tumour Removed

A team of neurosurgeons at a Spain hospital successfully removed a brain tumour while the patient was conscious and playing saxophone. With this approach it was possible to operate without damaging the part of the brain involved in musical language.


Aguilera, who was told he had a brain tumour after suffering dizzy spells, said: “Music is what has accompanied me half a lifetime, so when the doctors told me I could do that, I did not think twice.”

This is clearly one of the many advances in medicine and neuroscience. More information here.

Interactive Brain Injury

The Traumatic Brain Injury (TBI) from the Center of Excellence for Medical Multimedia enables the use of this Interactive Brain where it shows and describes the different brain areas, function and result of injury. 


This online application offers 5 view options: Side view, Inside view, Visual anatomy, Motility and Left & right brain function. At the right column 3 other options: Description area, Function and Result of injury. The next picture shows a visual anatomy of optic radiations:


The trauma can cause nerve cells in the brain to stretch, tear, or pull apart, making it difficult or impossible for the cells to send messages from one part of the brain to another, and to the rest of the body. TBI can interfere with how the brain works, including thinking, remembering, seeing, and controlling movements. Traumatic brain injury can range from mild to very severe depending on many things, including the force of the trauma, previous brain injuries and how quickly emergency medical treatment is given.

Thinking the Music and Write it Directly

Hi-tech channel from Euronews has just published a small report about a "new way of thinking" the music. This research group predicts that in a near future, using the BCIs, will be possible  to “think” directly the music onto the page, without having to write it down.


Pianist Francesco Prode is wearing a neural sensor on his head, which picks up his brainwaves and sends them to a laptop. In front of him is a Kinect motion sensor of the kind used in video games. As he passes his hand in front of the device, just like an orchestra director, the pianist activates the reproduction of a fragment of piano sound previously recorded by a computer.

A Subject-independent Pattern-based BCI

A provisional PDF file corresponding to the article "A Subject-independent Pattern-based BCI", created by Andreas M. Ray,  Ranganatha Sitaram,  Mohit Rana,  Emanuele Pasqualotto,  Korhan Buyukturkoglu,  Cuntai Guan,  Kai Keng Ang, Cristián Tejos,  Francisco J. Zamorano, Francisco Aboitiz, Niels Birbaumer and Sergio Ruiz was published in Frontiers in Behavioral NeuroScience


"A brain-computer interface (BCI) enables direct communication from the brain to devices, bypassing the traditional pathway of peripheral nerves and muscles. Traditional approaches to BCIs require the user to train for weeks or even months to learn to control the BCI. In contrast, BCIs based on machine learning only require a calibration session of less than an hour before the system can be used, since the machine adapts to the user's existing brain signals. However, this calibration session has to be repeated before each use of the BCI due to inter-session variability, which makes using a BCI still a time-consuming and an error-prone enterprise. In this work, we present a second-order baselining procedure that reduces these variations, and enables the creation of a BCI that can be applied to new subjects without such a calibration session. The method was validated with a motor-imagery classification task performed by 109 subjects. Results showed that our subject-independent BCI without calibration performs as well as the popular common spatial patterns (CSP)-based BCI that does use a calibration session."

The National Center for Adaptative Neurotechnologies (NCAN) located on New Scotland Avenue in Albany, New York, are building an infrastructure that supports real-time interactions with the central nervous system (CNS) helping to restore a skill such as locomotion.


"Progress in medical science now enables people with severe paralysis to live for many years. Many of these individuals have great difficulty in communicating. Some may even be entirely "locked in" to their bodies: their minds are functioning, but they cannot move a single muscle to communicate in any way. The capacity for simple communication could greatly improve the quality of their lives. The Center for Adaptive Neurotechnologies has addressed this problem by developing a new generation of brain-based communication devices (BCI) that can provide communication and control functions to people who have lost muscle control. By recording brain waves from the scalp and then decoding them, this system allows people to move a computer cursor up/down and left/right, to spell words, and to perform other simple control functions."


The research areas are divided by Guiding Beneficial Plasticity, Brain-Computer Interface (BCI) Based Rehabilitation and Characterizing and Interacting with Cortical Processes. During 2015 some papers have been published in peer-reviewed neuroscientic, neuroengineering and clinical journals related to this subjects:

Identification of Motor Imagery Movements from EEG Signals Using Dual Tree Complex Wavelet Transform

Conference: 4th ICACCI ’15, Kerala, India
DOI: 10.1109/ICACCI.2015.7275623
Abstract: (...) Dual Tree Complex Wavelet Trans-form (DTCWT) domain based feature extraction method has been proposed to identify left and right hand motor imagery movements from EEG signals. After first performing auto-correlation of the EEG signals to enhance the weak brain signals and reduce noise, the EEG signals are decomposed into several bands of real and imaginary coefficients using DTCWT. The energy of the coefficients from relevant bands have been extracted as features and from the one way ANOVA analysis, scatter plots, box plots and histograms, this features are shown to be promising to distinguish various kinds of EEG signals. (...) K-nearest neighbor (KNN) classifiers have been shown to provide a good mean accuracy of 91.07% which is better than several existing techniques.

Brain Driver - Control a Car using Your Mind

AutoNOMOS Labs is a German company that is working on a modular system for the operation of autonomous or semi-autonomous cars. 
Using AutoNOMOS, it is be possible to detect impending dangers on roads, highways, and crossings at an early stage and accidents can be prevented. Once the technology is ready, it will be introduced at first on private property and, finally, in public traffic. The project will make a significant contribution to the development of accident-free, efficient, and environmentally friendly mobility.



In the following video we can see the use of the device EPOC from the Emotiv company. By reading the brain electrical signals recorded at the level of the scalp (EEG) it is possible to identify patterns of behavior. In this particular case driver intentions are identified to turn left, turn right and also accelerate or brake


At this moment tests are being carried out on a large place as the airport runway. In my understanding this "car technology" will need time to grow up until a complete solution can be used in a real scenario within our roads.
Not advancing a date in concrete, one day will be possible to think something like: "Stop here and park on the right side!" :-)

Neuroplasticity using a Bicycle

Here is an excellent example of neuroplasticity where the brain reorganize itself by forming new neural connections throughout life. In this funny and simple experience the wheel of the bicycle was changed, reversing the direction of intention. The instantaneous result was the expected: Falls to the ground! 


But the most interesting is how our brain, after some days or weeks, is able to adapt to this new reality. Especially if you are a child! :-)

FlexCtrl - A new EEG / BCI capture device

A new EEG capture device with 32-channel headset was announced.  This project was found as a BCI crowdfunding campaign in Indiegogo.


Their web page is still under constrution and in my opinion this project does not respond to some fundamental questions: 

  • What kind of dry sensors are used?
  • How does it react with long hair?
  • When the SDK will be available?

Let's wait for the answers...!

Play computer games without using your hands or feet

New BCI solutions are increasingly common in laboratories and research institutes. One such example is the project developed by Christoph Hintermüller and his team from g.tec Guger Technologies. He says: “We have developed so called brain-computer interfaces which allow the user to control different devices and programmes without hands, by means of the user’s thoughts.


This is one more approach to play a computer game hands-free. Using SSVEP the user selects the commands by simply looking at the blinking arrows on the screen. The frequency of the flashing is reproduced in the brain cortex and read by the electrodes at occipital area.

Also Arnau Manzanal of the research and development department says: "As soon as we have understood the electroencephalography patterns produced by the groups of neurons in the brain, we can map the brain activity to any commands for any device, like a television or a motorised system for the home".

Structural change of brain cells caused by depression

The Champalimaud Foundation has just acquired a ultra-high field scanner that can deliver results 10x above the conventional MRI. It can be used in several studies of diseases such as multiple sclerosis or depression.


“In depressed patients, cells change structure, change shape and size. With the method that we have been developing in this lab, it could become possible to study these processes and, hopefully, to see these changes as they occur. Potentially in the future it will be useful for clinicians to select treatments and better diagnosis depression.”

This type of equipment can provide new answers on how the human brain works. Watch the video report here.
