Multicenter Study Comparative Study
Reduced fronto-cortical brain connectivity during NREM sleep in Asperger syndrome: an EEG spectral and phase coherence study.
To investigate whether sleep macrostructure and EEG power spectral density and coherence during NREM sleep are different in Asperger syndrome (AS) compared to typically developing children and adolescents. ⋯ Quantitative analysis of the EEG during NREM sleep supports the hypothesis of frontal dysfunction in AS.

Randomized Controlled Trial Multicenter Study Comparative Study
Assessment of a scalp EEG-based automated seizure detection system.
The purpose of this study was to evaluate and validate an offline, automated scalp EEG-based seizure detection system and to compare its performance to commercially available seizure detection software. ⋯ With comparable detection sensitivity, an improved false detection rate makes the automated seizure detection software more useful in clinical practice.

Randomized Controlled Trial Comparative Study
Reproducibility and influence of test modality order on thermal perception and thermal pain thresholds in quantitative sensory testing.
To evaluate the reproducibility of quantitative sensory testing (QST), performed with the method-of-limits (MLI) at different test intervals, by assessing the inter- and intra-individual variation of thermal cold (CT) and warm (WT) perception thresholds, and of thermal cold- (CPT) and heat pain (HPT) thresholds. ⋯ The findings show that QST with the MLI is a reliable tool for indirect evaluation of human small nerve fiber function.

Randomized Controlled Trial Comparative Study
Cutaneous perception thresholds of electrical stimulation methods: comparison of tDCS and tRNS.
Controlled blinded studies using transcranial electrical stimulation (tES) paradigms need a validated sham stimulation paradigm since an itching or tingling sensation on the skin surface under the electrode can be associated with current flow. ⋯ As tRNS has been shown to have similar aftereffects as anodal tDCS, this finding points to the application of tRNS as a possible alternative with a better blinding control.
