Here we consider research on the kinds of sensory information most effective as feedback during remote control of machines, and the role of virtual reality and telepresence in that research. We argue that full automation is a distant goal and that remote control deserves continued attention and improvement. Visual feedback to controllers has developed in various ways but autostereoscopic displays have yet to be proven. Haptic force feedback, in both real and virtual settings, has been demonstrated to offer much to the remote control environment and has led to a greater understanding of the kinesthetic and cutaneous components of haptics, and their role in multimodal processes, such as sensory capture and integration. We suggest that many displays using primarily visual feedback would benefit from the addition of haptic information but that much is yet to be learned about optimizing such displays.

Emotional effects of sertraline: novel findings revealed by meditation.

Am J Orthopsychiatry. 2006 Jan;76(1):134-7

Use of selective serotonin reuptake inhibitors continues to increase, as does concern about previously unrecognized, subtle side effects and questions about whether these drugs produce effects on healthy subjects. The authors report novel emotional effects identified by an experienced, psychologically healthy meditator who is a psychiatrist and researcher. On a meditation retreat, the subject identified a specific profile of emotional changes related to sertraline use. In particular, cognitive abilities and the emotions of fear and anger seemed unaffected. However, the emotions of sadness, happiness, rapture, and love were dramatically reduced in intensity and duration. ((c) 2006 APA, all rights reserved).

Effect of neurofeedback training on the neural substrates of selective attention in children with attention-deficit/hyperactivity disorder: a functional magnetic resonance imaging study.

Attention Deficit Hyperactivity Disorder (AD/HD) is a neurodevelopmental disorder mainly characterized by impairments in cognitive functions. Functional neuroimaging studies carried out in individuals with AD/HD have shown abnormal functioning of the anterior cingulate cortex (ACC) during tasks involving selective attention. In other respects, there is mounting evidence that neurofeedback training (NFT) can significantly improve cognitive functioning in AD/HD children. In this context, the present functional magnetic resonance imaging (fMRI) study was conducted to measure the effect of NFT on the neural substrates of selective attention in children with AD/HD. Twenty AD/HD children--not taking any psychostimulant and without co-morbidity-participated to the study. Fifteen children were randomly assigned to the Experimental (EXP) group (NFT), whereas the other five children were assigned to the Control (CON) group (no NFT). Subjects from both groups were scanned 1 week before the beginning of the NFT (Time 1) and 1 week after the end of this training (Time 2), while they performed a Counting Stroop task. At Time 1, for both groups, the Counting Stroop task was associated with significant loci of activation in the left superior parietal lobule. No activation was noted in the ACC. At Time 2, for both groups, the Counting Stroop task was still associated with significant activation of the left superior parietal lobule. This time, however, for the EXP group only there was a significant activation of the right ACC. These results suggest that in AD/HD children, NFT has the capacity to normalize the functioning of the ACC, the key neural substrate of selective attention.
