Effects of Lee Silverman Voice Treatment (LSVT LOUD) on Swallowing in Patients with Progressive Supranuclear Palsy: A Pilot Study.

Objectives: Progressive supranuclear palsy (PSP) is an uncommon progressive neurodegenerative disease with no effective cure at present. The initial symptoms resemble those of Parkinson's disease; however, the prevalence of PSP is about one-tenth that of Parkinson's disease. In many cases, dysphagia is severe, and the development of dysphagia is an early predictor of life expectancy.

Neural Processing Mechanism of Mental Calculation Based on Cerebral Oscillatory Changes: A Comparison Between Abacus Experts and Novices.

: Abacus experts could mentally calculate fast some mathematical operations using multi-digit numbers. The temporal dynamics of abacus mental calculation are still unknown although some behavioral and neuroimaging studies have suggested a visuospatial and visuomotor neural process during abacus mental calculation. Therefore, this contribution aims to clarify the significant similarities and the differences between experts and novices by investigating calculation-induced neuromagnetic responses based on cerebral oscillatory changes.

Frequency-specific genetic influence on inferior parietal lobule activation commonly observed during action observation and execution.

Brain activity relating to recognition of action varies among subjects. These differences have been hypothesised to originate from genetic and environmental factors although the extent of their effect remains unclear. Effects of these factors on brain activity during action recognition were evaluated by comparing magnetoencephalography (MEG) signals in twins.

Non-invasive detection of language-related prefrontal high gamma band activity with beamforming MEG.

High gamma band (>50 Hz) activity is a key oscillatory phenomenon of brain activation. However, there has not been a non-invasive method established to detect language-related high gamma band activity. We used a 160-channel whole-head magnetoencephalography (MEG) system equipped with superconducting quantum interference device (SQUID) gradiometers to non-invasively investigate neuromagnetic activities during silent reading and verb generation tasks in 15 healthy participants.

Noninvasive spatiotemporal imaging of neural transmission in the subcortical visual pathway.

Spatiotemporal signal transmission in the human subcortical visual pathway has not been directly demonstrated to date. To delineate this signal transmission noninvasively, we investigated the early latency components between 45 ms (P45m) and 75 ms (N75m) of visually-evoked neuromagnetic fields (VEFs). Four healthy volunteers participated in this study.
