Title: A preliminary study of clinical assessment of left unilateral spatial neglect using a head mounted display system (HMD) in rehabilitation engineering technology

Tanaka T, Sugihara S, Nara H, Ino S, Ifukube T.

Unilateral spatial neglect (USN) is a common syndrome in which a patient fails to report or respond to stimulation from the side of space opposite a brain lesion, where these symptoms are not due to primary sensory or motor deficits. The purpose of this study was to analyze an evaluation process system of USN in various visual fields using HMD in order to understand more accurately any faults of USN operating in the object-centred co-ordinates. Eight stroke patients participated in this study and they had Left USN in clinical test, and right hemisphere damage was checked by CT scan. Assessments of USN were performed the BIT common clinical test ( the line bisection test and the stars cancellation test) and special tests the zoom-in condition (ZI) condition and the zoom-out condition (ZO) condition. The subjects were first evaluated by the common clinical test without HMD and then two spatial tests with HMD. Moreover, we used a video-recording for all tests to analyze each subject's movements. For the line bisection test under the commonl condition, the mean percentage of the correct answers at the left side in the test paper was 94.4%. In the ZI condition, the left side was 61.8.% and the right side was 92.4.%. In the ZO condition, the left side was 79.9% and the right side was 91.7.%. There were significant differences among the three conditions. The results of the stars cancellation test also showed the same tendency as the line bisection test. The results showed that the assessment of USN using a technique of HMD system may indicate the disability of USN more than the common clinical tests. Moreover, it might be hypothesized that the three dimensional for USN test may be more related to various damage and occurrence of USN than only the two dimensional test.

We investigated the effects of cortical stimulation on mental rotation tasks in a patient with an electrode array placed over his left primary motor cortex. The array was implanted to relieve chronic pain resulting from right brachial plexus damage. Tasks involving motor imagery were slowed down by cortical stimulation, whereas those involving visual imagery were not. When the patient performed the motor-imagery task, the interference effect on response times disappeared if the stimulator was switched off. We also probed two of the sites (anterior-lateral and posterior-medial position), and found that stimulation of the more anterior-lateral one consistently disrupted motor imagery.

This study used an open clinical trial to test a cognitive-behavioral treatment for public-speaking anxiety that utilized virtual reality as a tool for exposure therapy. Treatment was completed by participants (n=10) meeting the Diagnostic and Statistical Manual of Mental Disorders (DSM)-IV criteria for social phobia, or panic disorder with agoraphobia in which public speaking was the predominantly feared stimulus. Treatment was conducted by a licensed psychologist in an outpatient clinic. Treatment consisted of eight individual therapy sessions, including four sessions of anxiety management training and four sessions of exposure therapy using a virtual audience, according to a standardized treatment manual. Participants completed standardized self-report questionnaires assessing public-speaking anxiety at pre-treatment, post-treatment, and 3-month follow-up. Participants were asked to give a speech to an actual audience at pre- and post-treatment. Results showed decreases on all self-report measures of public-speaking anxiety from pre- to post-treatment, which were maintained at follow-up (n=8; all P<.05). Participants were no more likely to complete a speech post-treatment than at pre-treatment. This study provides preliminary evidence that a cognitive-behavioral treatment using virtual reality for exposure to public speaking may reduce public-speaking anxiety and suggests that further research with a controlled design is needed.

Deviceforge.com today reports that a company has just started marketing a technology that inexpensively adds face recognition to camera-equipped cellphones. Oki's "Face Sensing Engine" (FSE) "middleware" decodes facial images within 280mS on a 100MHz ARM9 processor, and can restrict access to mobile devices by recognizing their owners.

Besides security applications, this new technology could have interesting applications in the field of neurorehabilitation. For example, the implementation of face recognition may help brain-injured patients suffering from neurodegenerative diseases to recognize their relatives and friends

Oki lists the following key features of its FSE technology:

• Compact system footprint -- requires approximately 260KB on an ARM9 processor
  
• Fast image processing -- requires approximately 280mS on a 100MHz ARM9 processor
  
• Face recognition algorithm automatically adjusts to ambient lighting conditions
  
• Supported processor architectures -- ARM9, SH Mobile, and others

Abstract. Drug craving has purportedly been linked to relapse and to substance use. For over two decades, cue reactivity has been a viable method to assess craving and physiological reactions to drug stimuli. However, traditional cue reactivity has faced the following limitations: austere situations or stimuli, lack of complex cues, lack of standardization, and limited generalization outside of the lab setting. In order to improve cue methodologies, a virtual reality (VR) nicotine cue reactivity assessment system (VR-NCRAS) was developed and tested in a controlled experimental trial. Ten nicotine dependent smokers were exposed to VR smoking cues and VR neutral cues in a standardized, timed, computer controlled experiment. Subjective craving and physiological responses were recorded and compared across VR-NCRAS stimuli. Subjective cigarette craving increased significantly and corresponding physiological reactivity was observed in response to VR smoking cues. VR neutral cues did not result in subjective or physiological changes consistent with craving. Implications of these findings on substance abuse research and treatment are discussed.

"...Words like "intelligence", "awareness" and "agency" describe particular and peculiar behaviors performed effectively and appropriately in certain locations and situations. We do not need to imagine that they indicate anything other than that. What is important is not what happens within us, but rather what happens between us in the medium of language in which we communicate, in the social institutions within which we operate and in the culture within which we've been conditioned - at this point in our history and so on, depending on our frame of reference. To talk of agency is to refer to an intentional act defined within a very small frame of reference. [...] In the body performances, the skin has been stretched, the body has been probed and its limbs have been extended. The interest is to construct alternate interfaces that explore the absent, alien, involuntary and automated. What we experience is emptiness, ambiguity and uncertainty. We fear what we have always been and what we have already become -- a zombie with no mind -- a body that performs involuntarily..."

CNET News.com interviews Mike Merzenich, a neuroscientist, on how high-tech is shaping human intelligence. Merzenich, who is also a high-tech entrepreneur, focuses on designing and developing computer applications that support cognitive skills such as memory, attention, and language processing.

In this interview, Merzenich claims that massive exposure to technologies such as video games, television and the Internet is affecting brain evolution. He observes that in each stage of cultural development human beings had to develop novel skills and abilities. The progressive accumulation of these skills determined significant changes in our central nervous system, which is now very different from the brain of our ancestors. As culture and technology are still evolving, the challenges faced by brains are continuously changing and elaborating. Starting from these premises, Merzenich suggests that continuous exercise can help to preserve and maintain cognitive skills and abilities, and assumes that brain fitness will be an important part of every future, well-organized life.

A special issue of the journal Virtual Reality will be devoted to the use of Collaborative virtual environments to support creativity. Here is an excerpt from the journals' call for papers:

Creative processes often are collaborative in nature, with a group of people reflecting on an overall theme, jointly contributing thoughts interactively, and ultimately generating new ideas. Collaborative virtual environments (CVEs) to support this process, thus, should support the group, provide a creative atmosphere and comfortable environment, and support the seamless expression and visualization of ideas. This requires the environment to be inspiring, to enable a wide range of design options, to allow multiple and appropriate types of interaction, to provide for seamless interaction, advanced visualization technologies and simplified sharing mechanisms. Example application areas of such systems are the design and development of computer games, art, product design, fashion, digital storytelling environments, entertainment services, advertising, and architecture or urban planning. The aim of this special issue is to provide an overview of innovative and state-of-theart research on Collaborative Environments in Virtual Reality which support the creative process. Paper contributions should discuss in general how to support creativity with collaborative tools and virtual environments.

Research questions cover a wide range of topics such as how to

• allow participants with various professional backgrounds, working languages,
  and ways of expressing their ideas to collaborate with each other locally and
  over distance
• allow for quick and efficient selection of options to express and visualize
  innovative ideas, going well beyond support for 2D drawings, text and voice
• provide a non-technical, human-friendly and supportive work environment
  with the focus on creativity
• support the design of multi-dimensional interactive applications
• keep an overview on different activity lines in both the design and the use of
  multilevel, multi-dimensional applications

The EU Commission adopted a Green Paper on Mental Health on 17 October designed to tackle mental illnesses in Europe. The Green Paper, 'Promoting the mental health of the population: Towards a strategy on mental health for the European Union', aims to launch a public consultation on how better to tackle mental illness and promote mental well-being in the EU.
Mental illness affects over 27 per cent of European adults every year, and is responsible for the majority of the annual 58,000 deaths by suicide, more than the numbers who die from motor vehicle traffic accidents. Mental health levels can have a significant influence on the economic and social welfare of society. As well as the challenges of mental ill health for the health sector, and the implications for the affected citizens and their families, mental illness imposes significant costs on society and its economic, educational, social, criminal and justice systems. Moreover, stigma and discrimination linked to mental disorders undermine fundamental rights.

A conference to launch the Green paper will be held in Luxembourg on 24 October.

Draft agenda

The launch conference will be followed by three thematic meetings until end of May 2006:
1) Meeting 1: “Promotion and prevention in mental health” (fourth quarter of 2005);
2) Meeting 2: “Social inclusion and fundamental rights in mental health” (first quarter of 2006);
3) Meeting 2: “Information, data and knowledge in mental health” (second quarter of 2006).
