Announcement and Call for Papers: Affective BCI Workshop, Memphis, USA

2nd Workshop on Affective Brain-Computer Interfaces (aBCI) Workshop atACII 2011 (October 9-12), Memphis, USA, October 9, 2011

http://hmi.ewi.utwente.nl/abci2011http://www.acii2011.org

The second workshop on affective brain-computer interfaces willexplore the advantages and limitations of using neuro-physiologicalsignals as a modality for the automatic recognition of affective andcognitive states, and the possibilities of using this informationabout the user state in innovative and adaptive applications. The goalis to bring researchers from the communities of brain computerinterfacing, affective computing, neuro-ergonomics, affective andcognitive neuroscience together to present state-of-the-art progressand visions on the various overlaps between those disciplines.

Recent research in brain-computer interfaces (BCI) shows that brainactivity can be used as an active/voluntary, or passive/involuntarycontrol modality in man-machine interaction. While active BCIparadigms have received a lot of attention in recent years, researchon passive approaches to BCI still desperately needs concertedactivity. However, it has been shown more than once that brainactivations can carry information about the affective and cognitivestate of a subject, and that the interaction between humans andmachines can be aided by the recognition of those user states. Toachieve robust passive BCIs, efforts from applied and basic scienceshave to be combined. On the one hand, applied fields such as affectivecomputing aim at the development of applications that adapt to changesin the user states and thereby enrich the interaction, leading to amore natural and effective usability. On the other hand, basicresearch in neuroscience advances our understanding of the neuralprocesses associated with emotions. Furthermore, similar advancementsare being made for more cognitive mental states, for example,attention, fatigue, and work load, which strongly interact withaffective states.

Topics of interest include, but are not limited to:

* emotion elicitation and data collection for affective BCI* detection of affective and cognitive states with BCI and other modalities* adaptive interfaces and affective BCI

Invited Talk:'Brain Dynamics of Affective Engagement' by Scott Makeig, SCCN,University of California at San Diego, USA

The workshop will be held in conjunction with the 4th Internationalconference on Affective Computing and Intelligent Interaction(ACII2011) at the FedEx? Institute of Technology at the University ofMemphis, TN.

Brain Computer Interfacing in 2011 - From EEG to cortical implants

Science is on the verge of physically integrating human brain and advanced technology in the service of rehabilitation in paralysed people. Recordings of the brain capture detailed neuronal events that can be used to convey intentions for control in computer programs or of robotic limbs. Non-invasive and intracranial solutions utilize electrophysiological signals, but from different neuronal population sizes. Size matters as it determines the detail of information that can be used for BCI, ranging from single neurons to tens of millions depending on type and position of electrodes. Different BCI solutions are likely to serve different needs in patients. The majority of current BCI technologies use EEG scalp electrodes, for detection of several types of mental events such as imagined movements and the P300 oddball response. EEG-based BCI is now close to clinical implementation in the homes of paralysed people. Several human pilot studies have been conducted with intracranial BCI. Amazing achievements have been reported in research with non-human primates, paving the road for further development of human BCI. Much of the required technology for signal processing and decoding currently still resides outside of the body, but with state of the art electronics fully implantable devices are conceivable.

What will be presented?In 2008 we organized a symposium dedicated to the State of the Art in BCI, with a focus on implantable systems. Now, three years later we evaluate the progress. Thirteen speakers will present the latest developments in both scalp-EEG BCI and in all aspects relevant to implantable systems. Scalp-EEG solutions will be discussed in the light of historical developments and of hurdles on the road to commercial availability, and experts will present their views on the future. Implantable systems have to deal with various issues of safety and justification and are therefore more challenging to accomplish. Several approaches are now adopted that vary in the brain areas and functions that are targeted, the type of electrode (cortex penetrating or surface types), and the dimensionality of information decoding (from a simple yes/no switch to complex grasp trajectories). So, what is the current state of affairs? What kind of systems can we expect to see, and when? Key players in the field of BCI will present where the research stands and what is envisioned for the near future.

When? May 20&21, 2011

Researchers' Night: De macht van het brein

Het brein is een mysterie. Onderzoekers kraken hun hersenen om die complexe massa draadje voor draadje te ontwarren.

Valt Parkinson straks te genezen en zijn ADHD en depressies ooit eenvoudig te behandelen? Kunnen mens en machine één worden en zijn protheses dan integraal onderdeel van onszelf? Worden computerspelletjes in de toekomst via gedachten gespeeld? Tijdens de Researchers' Night in LUX op 24 september vertellen en debatteren wetenschappers over wat ze nu al kunnen en wat er in de toekomst mogelijk zal zijn. Maar ook: waar ligt de grens, wanneer slaat de groeiende controle op het brein om in Big Brother-achtige praktijken? De mens is nu verantwoordelijk, maar kunnen wij die macht wel aan?

De wetenschappers nemen hun laboratorium mee naar LUX. Met demonstraties laten ze zien hoe hersenonderzoek in z'n werk gaat. Hersencellen worden live stilgelegd of juist wakker geschud - wie durft?

Brain Computer Interfacing (BCI) aims at making use of brain signalsfor e.g. the control of objects, spelling, gaming and so on. This talkwill first provide a brief overview of Brain Computer Interfacefrom a machine learning and signal processing perspective. Inparticular it shows the wealth, the complexity and the difficulties ofthe data available, a truely enormous challenge: In real-time amulti-variate very strongly noise contaminated data stream is to beprocessed and neuroelectric activities are to be accuratelydifferentiated in real time.

Finally, I report in more detail about the Berlin Brain Computer(BBCI) Interface that is based on EEG signals and take the audienceall the way from the measured signal, the preprocessing and filtering,the classification to the respective application. BCI as a newchannel for man-machine communication is discussed in a clincialsetting and for gaming.

Donders Lecture by prof. dr. Anthony T. Barker (Title: the interaction between electromagnetic fields and the human body: the birth and the development of Transcranial Magnetic Stimulation)

* Date : 23-09-2008
  • Time : 16.00-17.30
  • Location : Hippocrateszaal, Geert Grooteplein Noord 21 (route 77), Radboud University Nijmegen Medical Centre

Abstract: Everyday, we are all exposed to electromagnetic fields from a variety of sources. Some of these exposures are intentional: large magnetic pulses can stimulate the human cortex by inducing currents in the brain. In the 23 years after its first practical demonstration, Transcranial Magnetic Stimulation (TMS) has developed into a principal tool for neuroscientific research. Prof. Barker will give an introduction to the principles, early development and state-of-the art of this application of electromagnetic fields, including a live demonstration. In addition, he will talk about the controversies surrounding the inadvertent exposure to electromagnetic sources such as mobile phones and overhead power cables. Sources and magnitudes of these electromagnetic fields will be discussed, to put the public concern and scientific debate over the possible health risks into perspective.

CV: Anthony T. Barker, specialized in Medical Electronics, obtaining his Ph.D. from the University of Sheffield in 1976. From 1976 until 1990 he worked as physicist at the Royal Hallamshire Hospital, as well as holding the title of Lecturer at the University of Sheffield (1977-1999). Since 1999 he has been a professor at the University of Sheffield and is a Consultant Clinical Scientist in the Department of Medical Physics and Clinical Engineering at the Royal Hallamshire Hospital. Prof. Barker has given numerous prestigious and invited lectures all over the globe. For his development of Magnetic Nerve Stimulation (MNS) and one of its most popular applications, Transcranial Magnetic Stimulation (TMS), he has received awards from the Institution of Engineering and Technology and the Institute of Physical Sciences in Medicine. TMS is a method of non-invasively inducing temporary lesions in specic areas of cortex, changing cortical excitability and directly stimulating the cortex. More than 3000 papers on TMS have arisen from his original papers on the subject. This extremely popular technology has seen a multitude of applications in both research and clinical settings. In addition to his work in the high level magnetic fields of MNS, Prof. Barker is also interested in the biological effects of low-level electromagnetic fields such as those from mobile phones and overhead power cables, and in electrophysiological signal analysis.

Gamen met je Brein: Op zoek naar niet-medische toepassingen voor Brain-Computer Interfacing

Beste relatie,

Dankzij de mogelijkheid verschillende soorten hersenactiviteit te meten en te interpreteren wordt het zo langzamerhand, in beperkte mate en voor beperkte taken, mogelijk computers via hersenactiviteit aan te sturen.

Er zijn veel (medisch georiënteerde) toepassingen denkbaar voor Brain-Computer Interfacing (BCI). Denk aan het aansturen van een toetsenbord, een prothese of bijvoorbeeld een rolstoel. Van daaruit is het betrekkelijk eenvoudig om een stap te maken naar niet-medische toepassingen. Een ieder kan in een situatie terecht komen waarin het nuttig kan zijn om naast de fysieke aanstuurmogelijkheden, een extra modaliteit ter beschikking te hebben. Tevens kan het nuttig zijn dat de computer weet heeft van de mentale toestand van de gebruiker.

Bijzonder interessant is het gebruik van BCI in spelomgevingen. In die omgevingen kan naar hartelust geëxperimenteerd worden met BCI en kan er sprake zijn van veel, heel veel, gebruikers. Na een niet-technische inleiding in wat BCI inhoudt en kan betekenen zullen we dan ook vooral kijken wat voor mogelijkheden er zijn voor BCI in spelomgevingen, wat er al gerealiseerd is en wat de belangstelling is van spelfabrikanten voor deze ontwikkeling.

Het achterliggende idee is dat als BCI in dit soort omgevingen van de grond komt, er van daaruit ook andersoortige, niet op spellen en niet op medisch gebruik gerichte toepassingen van de grond zullen komen. De onderwerpen tijdens deze boeiende sessie zullen geïllustreerd worden met veel videomateriaal.

BrainGain Lecture: Jonathan Rubin at UT Twente

  • Date : 30-01-2008
  • Time : 11-12h
  • Location : UT, Citadel T300
  • Title : A possible mechanism for the efficacy of subthalamic nucleus deep brain stimulation.
  • Abstract : The delivery of high-frequency stimulation (deep brain stimulation, or DBS) to the subthalamic nucleus (STN) or other target areas has become a widely used therapeutic option for the treatment of Parkinson's disease (PD) and other neurological disorders. The mechanisms underlying its effectiveness, however, remain unclear and under debate. Because lesions of the STN and DBS of the STN lead to similar therapeutic outcomes, it has been hypothesized that DBS blocks STN activity, causing an effective lesion. More recent studies, however, have suggested that DBS activates areas downstream from its target site. In the case of PD, this leads to the paradox that although increased inhibitory basal ganglia output is associated with motor symptoms, STN-DBS may increase inhibitory output further yet relieve these symptoms.
    In this talk, I will present work done in a computational model that explains a possible resolution of this paradox. A key aspect of this explanation is that STN-DBS may regularize basal ganglia output, eliminating the pathological rhythmicity associated with PD. The work that I will discuss provides the first detailed demonstration of how such regularization could normalize motor processing, through a restoration of thalamocortical relay in areas targeted by the basal ganglia. In addition to a purely computational exploration of the mechanism involved, I will present results that arise when basal ganglia outputs recorded from MPTP monkeys are incorporated into a computational model. These results show significant distinctions between thalamocortical relay under parkinsonian conditions without DBS, with sub-therapeutic DBS, and with therapeutic DBS.

  • Title : Using Electrocorticography for Brain-Computer Interfacing and Detailed Single-Trial Decoding of Human Behavior
  • More information : http://www.fcdonders.ru.nl
  • Abstract : Brain-Computer Interfaces (BCIs) convert brain signals into outputs that communicate a user's intent. BCIs can be used by people who are severely paralyzed to communicate and interact with their environment. However, practical applications of BCI technology are currently impeded by the limitations and requirements of the prevailing non-invasive and invasive methods.
    Non-invasive BCIs use electroencephalographic activity (EEG) recorded from the scalp. While EEG-based BCIs support higher performance than often assumed, the acquisition of high levels of control typically requires extensive user training. Invasive BCIs use local activity from multiple neurons recorded within the brain. Signals recorded within cortex have higher fidelity, but implementations of intracortical BCIs are currently impeded mainly by the difficulties in maintaining stable long-term recordings.
    Electrocorticographic (ECoG) recording from the cortical surface could be a powerful and practical alternative to current non-invasive and invasive BCI recording methods. ECoG has higher spatial resolution than EEG, broader bandwidth, higher characteristic amplitude, and far less vulnerability to artifacts such as EMG or ambient noise. At the same time, because ECoG does not require penetration of the cortex, it is likely to have greater long-term stability and to produce less tissue damage and reaction than intracortical recordings.
    In this talk, I will discuss the use of ECoG for one- and two-dimensional BCI control. I will also describe how ECoG can be used to accurately decode specific aspects of behavior (e.g., hand or finger movements, or speech) in single trials in humans. These results disprove the widespread assumption that only action- or field potential recordings from intracortical microelectrodes can provide highly specific task-related information.
