TL;DR: In this article, the authors reanalysed 31 primary data sets as a single large sample (N = 2876) to provide a more definitive view of the association between bipolar disorder and cognitive impairment.

TL;DR: Directional uncertainty is established as an important determinant of beta-band power during motor preparation and neural activity in the sensorimotor cortex during motor Preparation covaries with directional uncertainty.

TL;DR: The results indicate that the power in the alpha-band is associated briefly with cue size, but is otherwise an undifferentiated indication of neural activation, whereas the power of the beta-band reflects the level of motor preparation.

TL;DR: Investigating the relation between impulsivity and the modulation of beta band oscillatory activity associated with action planning and execution found that the decrease of relative beta band power during action planning in the left fronto-central group of channels was more pronounced in the high impulsivity group than in the low impulsiveness group.

TL;DR: The superior parietal lobule (SPL) of six human subjects was imaged at 4 T during mental traversing of a directed maze path to demonstrate the orderly involvement of the SPL in this function, and document a new, orderly functional organization of the SPL with respect to mental tracing.
