Can neurofeedback training enhance performance?

Can neurofeedback training enhance performance? An evaluation of the evidence with implications for future research.

Appl Psychophysiol Biofeedback. 2005 Dec;30(4):347-64

Authors: Vernon DJ

There have been many claims regarding the possibilities of performance enhancement training. The aim of such training is for an individual to complete a specific function or task with fewer errors and greater efficiency, resulting in a more positive outcome. The present review examined evidence from neurofeedback training studies to enhance performance in a particular area. Previous research has documented associations between specific cortical states and optimum levels of performance in a range of tasks. This information provides a plausible rationale for the use of neurofeedback to train individuals to enhance their performance. An examination of the literature revealed that neurofeedback training has been utilised to enhance performance from three main areas; sport, cognitive and artistic performance. The review examined evidence from neurofeedback training studies within each of these three areas. Some suggestive findings have been reported with regard to the use of neurofeedback training to enhance performance. However, due to a range of methodological limitations and a general failure to elicit unambiguous changes in baseline EEG activity, a clear association between neurofeedback training and enhanced performance has yet to be established. Throughout, the review highlights a number of recommendations to aid and stimulate future research.

Attention rehabilitation following stroke and traumatic brain injury

Attention rehabilitation following stroke and traumatic brain injury. A review.

Eura Medicophys. 2006 Feb 1;

Authors: Michel JA, Mateer CA

Attentional capacities, which are frequently impaired following brain injury, have also been found to be amenable to rehabilitation. This review discusses various approaches to attention rehabilitation in adult clients following stroke and traumatic brain injury. Attention process training has been accepted by many as a practice standard in postacute clients, however, its ability to generalize to new situations and to functional capacities is unclear. There is evidence for the use of psychostimulant medication, which may be most helpful when prescribed in combination with attention training. Biofeedback is a new avenue for intervention and is beginning to show some promising RESULTS: Rather than train underlying processes, another approach which shows promising results in a few small studies is training clients on specific functional skills, such as driving or vocational duties. Finally, modifications to the environment, implementation of strategies, provision of emotional support, and introduction of external supports/aids are important parts of a rehabilitation program, especially as the client returns to their home environment.

Science News: Fitness is good for the brain

From the latest article in Science News Online:

New research suggests that physical exercise encourages healthy brains to function at their optimum levels. Fitness prompts nerve cells to multiply, strengthens their connections, and protects them from harm. Benefits seem to extend to brains and nerves that are diseased or damaged. These findings could suggest new treatments for people with Alzheimer's disease, Parkinson's disease, and spinal cord injuries.
Preliminary studies indicated that when lab animals exercise, their nerve cells release chemicals called neurotrophic factors. These proteins buffer nerve cells against illness or injury, prompt them to grow and multiply, and strengthen each neuron's connection with other nerve cells.
Furthermore, memory tests given to 1,740 people over 65 during a 6-year project have linked moderate exercise to reduced risk of dementia. These results were published in the Jan. 17 Annals of Internal Medicine by a Seattle research team.

Improvement and generalization of arm motor performance through motor imagery practice

Improvement and generalization of arm motor performance through motor imagery practice 
Neuroscience. 2006;137(3):761-72.
Gentili R, Papaxanthis C, Pozzo T.
This study compares the improvement and generalization of arm motor performance after physical or mental training in a motor task requiring a speed-accuracy tradeoff. During the pre- and post-training sessions, 40 subjects pointed with their right arm as accurately and as fast as possible toward targets placed in the frontal plane. Arm movements were performed in two different workspaces called right and left paths. During the training sessions, which included only the right path, subjects were divided into four training groups (n=10): (i) the physical group, subjects overtly performed the task; (ii) the mental group, subjects imagined themselves performing the task; (iii) the active control group, subjects performed eye movements through the targets, (iv) the passive control group, subjects did not receive any specific training. We recorded movement duration, peak acceleration and electromyographic signals from arm muscles. Our findings showed that after both physical and mental training on the right path (training path), hand movement duration and peak acceleration respectively decreased and increased for this path. However, motor performance improvement was greater after physical compared with mental practice. Interestingly, we also observed a partial learning generalization, namely an enhancement of motor performance for the left path (non-training path). The amount of this generalization was roughly similar for the physical and mental groups. Furthermore, while arm muscle activity progressively increased during the training period for the physical group, the activity of the same muscles for the mental group was unchanged and comparable with that of the rest condition. Control groups did not exhibit any improvement. These findings put forward the idea that mental training facilitates motor learning and allows its partial transfer to nearby workspaces. They further suggest that motor prediction, a common process during both actual and imagined movements, is a fundamental operation for both sensorimotor control and learning.

Training benefits brains in older people, counters aging factors

From the news release 

New research at the University of Illinois at Urbana-Champaign shows that training re-ignites key areas of the brain, offsetting some age-related declines and boosting performance. The findings, involving functional magnetic resonance imaging (fMRI), provide the first visible evidence for a relationship between behavioral performance and cortical processors involved in dual-task processing, said Arthur F. Kramer, a professor of psychology and researcher at the Beckman Institute for Advanced Science and Technology.

The study, published online this month in advance of regular publication by the journal Neurobiology of Aginng, also adds to other emerging data that refute the idea that opposite brain areas become activated to help aging people compensate for a loss of cognition. Older studies, Kramer said, did not look at the impacts of training. For the new study, researchers in Kramer's lab looked at areas of the brain known to be associated with executive control - scheduling, planning, juggling multiple tasks and working memory. These areas, the ventral and dorsal prefrontal cortexes, are tied to cognitive declines in aging.

Neural correlate of spatial presence

Neural correlate of spatial presence in an arousing and noninteractive virtual reality: an EEG and psychophysiology study

Cyberpsychol Behav. 2006 Feb;9(1):30-45

Authors: Baumgartner T, Valko L, Esslen M, Jäncke L

Using electroencephalography (EEG), psychophysiology, and psychometric measures, this is the first study which investigated the neurophysiological underpinnings of spatial presence. Spatial presence is considered a sense of being physically situated within a spatial environment portrayed by a medium (e.g., television, virtual reality). Twelve healthy children and 11 healthy adolescents were watching different virtual roller coaster scenarios. During a control session, the roller coaster cab drove through a horizontal roundabout track. The following realistic roller coaster rides consisted of spectacular ups, downs, and loops. Low-resolution brain electromagnetic tomography (LORETA) and event-related desynchronization (ERD) were used to analyze the EEG data. As expected, we found that, compared to the control condition, experiencing a virtual roller coaster ride evoked in both groups strong SP experiences, increased electrodermal reactions, and activations in parietal brain areas known to be involved in spatial navigation. In addition, brain areas that receive homeostatic afferents from somatic and visceral sensations of the body were strongly activated. Most interesting, children (as compared to adolescents) reported higher spatial presence experiences and demonstrated a different frontal activation pattern. While adolescents showed increased activation in prefrontal areas known to be involved in the control of executive functions, children demonstrated a decreased activity in these brain regions. Interestingly, recent neuroanatomical and neurophysiological studies have shown that the frontal brain continues to develop to adult status well into adolescence. Thus, the result of our study implies that the increased spatial presence experience in children may result from the not fully developed control functions of the frontal cortex.

Mind-operated devices: mental control of a computer using biofeedback

Mind-operated devices: mental control of a computer using biofeedback.

Cyberpsychol Behav. 2006 Feb;9(1):1-4

Authors: Parente A, Parente R

This study investigated whether people could learn to control a computer using a biofeedback interface that integrated their galvanic skin response (GSR), heart rate, and temperature. Twenty participants played a computer game using the biofeedback device, both individually and in pairs. Results indicated that most people learned to control the game after a single training session. The GSR measure was the most sensitive means of control. Pairs of participants controlled the device more effectively than single individuals did.

Fourth Workshop on Agents Applied in Health Care

A workshop held in conjunction with the ">17th European Conference on Artificial Intelligence, ECAI-2006

Riva del Garda, Italy, August 28th - September 1st, 2006

April 1st, 2006: Deadline for paper and demos submission

From the workshop website:

Multi-agent systems are one of the most exciting research areas in Artificial Intelligence. In the last eight years there has been a growing interest in the application of agent-based systems in health care. The first specialised workshop on this area was held at Autonomous Agents '2000 in Barcelona, Spain; several other workshops and special issues of journals have followed since then (ECAI-2002, Agentcities ID3-2003, ECAI-2004 and IJCAI-05). Moreover, a growing European community of researchers interested in the application of intelligent agents in health care emerged as a result of the activities within the AgentCities.NET European network and the AgentLink III Technical Forum Group on Healthcare Applications of Intelligent Agents. Thus, it may now be a good time for the specialists in the field to meet and report on the results achieved in this area, to discuss the benefits (and drawbacks) that agent-based systems may bring to medical domains, and also to provide a list of the research topics that should be tackled in the near future to make the deployment of health-care agent-based systems a reality.

Current topics of research include communication and co-operation between distributed intelligent agents to manage patient care, information agents that retrieve medical information from the Internet, and multi-agent systems that assist the doctors in the tasks of monitoring and diagnosis. A lot of methodological and technical problems are beginning to be discovered by the researchers that attempt to deploy agent-based systems in the medical area; just to name a few, there does not exist a universally accepted standard medical ontology, it is difficult to integrate new agent systems with legacy software, and these new agent-based systems should take into account rapidly changing national and international laws and regulations concerning the privacy of medical data and the security of the transaction of patient information between agents.

This one-day workshop will feature some of the following activities:

  • Presentation of state-of-the-art papers with the latest developments in the field.
  • Presentation of review-style papers.
  • Demos of practical applications of MAS in health care.
  • Panel discussion of the main problems that have to be faced to deploy real agent-based health-care applications.
  • Time for meeting colleagues in the field and discussing possible future collaborations.

Virtual reality cues for improvement of gait in patients with multiple sclerosis

Baram, Yoram PhD; Miller, Ariel MD, PhD

Neurology. 66(2):178-181, January 24, 2006.

OBJECTIVE: To study the effects of visual cues, provided through a portable visual-feedback virtual reality (VR) apparatus, on the walking abilities of patients with multiple sclerosis (MS). METHODS: On-line (display-on) and residual short-term therapeutic effects on walking speed and stride length were measured in 16 randomly selected patients with gait disturbances predominantly due to cerebellar ataxia. RESULTS: Patients whose baseline walking speed (BWS) was below the median showed an average on-line improvement of 13.46% in their walking speed, while patients whose BWS was above the median improved their speed by 1.47%. The average short-term residual therapeutic improvement in walking speed was 24.49% in patients with BWS below the median, and 9.09% in patients with BWS above the median. Similar results were obtained for improvements in stride length. These results of improved functions in patients are particularly noteworthy when compared with the lack of change in healthy control subjects. CONCLUSIONS: Patients with multiple sclerosis showed improvement in walking abilities using virtual reality visual-feedback cues.

Humans Ignore Motion and Stereo Cues in Favor of a Fictional Stable World

Humans Ignore Motion and Stereo Cues in Favor of a Fictional Stable World.

Curr Biol. 2006 Feb 21;16(4):428-432

Authors: Glennerster A, Tcheang L, Gilson SJ, Fitzgibbon AW, Parker AJ

As we move through the world, our eyes acquire a sequence of images. The information from this sequence is sufficient to determine the structure of a three-dimensional scene, up to a scale factor determined by the distance that the eyes have moved . Previous evidence shows that the human visual system accounts for the distance the observer has walked and the separation of the eyes when judging the scale, shape, and distance of objects. However, in an immersive virtual-reality environment, observers failed to notice when a scene expanded or contracted, despite having consistent information about scale from both distance walked and binocular vision. This failure led to large errors in judging the size of objects. The pattern of errors cannot be explained by assuming a visual reconstruction of the scene with an incorrect estimate of interocular separation or distance walked. Instead, it is consistent with a Bayesian model of cue integration in which the efficacy of motion and disparity cues is greater at near viewing distances. Our results imply that observers are more willing to adjust their estimate of interocular separation or distance walked than to accept that the scene has changed in size.

Cognitive and Emotional Health Project

Via Brain Blog

The US National Institute on Aging (NIA), the National Institute of Mental Health (NIMH) and the National Institute of Neurological Disorders and Stroke (NINDS) have launched a new initiative, called Cognitive and Emotional Health Project. The goal of the initiative is to evaluate the state of the art in research on demographic, social and biologic determinants of cognitive and emotional health in aging adults.

From the website

"Three Institutes, the National Institute on Aging (NIA), the National Institute of Mental Health (NIMH) and the National Institute of Neurological Disorders and Stroke (NINDS), have joined efforts to launch a new trans-NIH initiative, Cognitive and Emotional Health Project: The Healthy Brain. There are now about 45 million Americans over age 60 and 117 million over age 40. Current evidence indicates that a large number of them are at substantial risk for cognitive impairment from many causes as they age. The same is true for emotional disorders. While research into biological mechanisms and environmental and social effects are yielding promising results in both animal and human studies, much remains to be discovered. Advances in understanding the positive and negative changes in cognition and emotion in adulthood, and what can be done to preserve and enhance positive outcomes, is at the core of the missions of the participating Institutes. The overall goal of the "Healthy Brain Project" is to assess the state of longitudinal and epidemiological research on demographic, social and biologic determinants of cognitive and emotional health in aging adults and the pathways by which cognitive and emotional health may reciprocally influence each other. A number of activities have been undertaken to accomplish these goals."
