Cerebellar tDCS Does Not Enhance Performance in an Implicit Categorization Learning Task.

Transcranial Direct Current Stimulation (tDCS) is a form of non-invasive electrical stimulation that changes neuronal excitability in a polarity and site-specific manner. In cognitive tasks related to prefrontal and cerebellar learning, cortical tDCS arguably facilitates learning, but the few studies investigating cerebellar tDCS, however, are inconsistent. We investigate the effect of cerebellar tDCS on performance of an implicit categorization learning task.

Comparison of Genome Sequences from Strains Isolated from Symptomatic and Asymptomatic Patients.

is a common cause of respiratory tract infections (RTIs) in children. We recently demonstrated that this bacterium can be carried asymptomatically in the respiratory tract of children. To identify potential genetic differences between strains that are carried asymptomatically and those that cause symptomatic infections, we performed whole-genome sequence analysis of 20 strains.
