Background: Transcranial direct current stimulation (tDCS) is currently being investigated as a non-invasive neuromodulation therapy for a range of conditions including stroke rehabilitation. tDCS affects not only the area underlying the electrodes but also other areas of the cortex and subcortical structures. This could lead to unintended alteration in brain functions such as autonomic control.

Magnetoencephalography (MEG) enables non-invasive recording of neuronal activity, with reconstruction methods providing estimates of underlying brain source locations and oscillatory dynamics from externally recorded neuromagnetic fields. The aim of our study was to use MEG to determine the effect of manual acupuncture on neuronal oscillatory dynamics. A major problem in MEG investigations of manual acupuncture is the absence of onset times for each needle manipulation.

"Visual capture" is the term used to describe vision being afforded a higher weighting than other sensory information. Visual capture can produce powerful illusory effects with individuals misjudging the size and position of their hands. The advent of laparoscopic surgical techniques raises the question of whether visual capture can interfere with an individual's rate of motor learning.

Interviews based on the Supported Employment Fidelity Scale were conducted with staff from five of the leading providers of supported employment. One provider obtained a good IPS adherence score, three a fair score and one a non-adherence score.

Platelet refractoriness due to human leucocyte antigen (HLA) alloimmunization is a significant risk to allogeneic bone marrow transplant recipients. To identify factors contributing to this risk, we reviewed the records of 317 consecutive, paediatric, allogeneic bone marrow transplant recipients at a single institution. The 6-year estimated cumulative incidence of platelet refractoriness due to HLA alloimmunization was 2.
