Medial profrontal cortex and anterior cingulate cortex in the generation of alpha activity induced by transcendental meditation: a magnetoencephalographic study.

Acta Med Okayama. 2006 Feb;60(1):51-8

Authors: Yamamoto S, Kitamura Y, Yamada N, Nakashima Y, Kuroda S

Previous EEG studies have shown that transcendental meditation (TM) increases frontal and central alpha activity. The present study was aimed at identifying the source of this alpha activity using magnetoencephalography (MEG) and electroencephalography (EEG) simultaneously on eight TM practitioners before, during, and after TM. The magnetic field potentials corresponding to TM-induced alpha activities on EEG recordings were extracted, and we attempted to localize the dipole sources using the multiple signal classification (MUSIC) algorithm, equivalent current dipole source analysis, and the multiple spatio-temporal dipole model. Since the dipoles were mapped to both the medial prefrontal cortex (mPFC) and anterior cingulate cortex (ACC), it is suggested that the mPFC and ACC play an important role in brain activity induced by TM.

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. 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.

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.
