Depression is a commonly occurring mental disorder, and investigations have been carried out into attentional bias in this condition. The aim of the present study was to investigate the interference inhibition for emotional words in depressed individuals in the emotional Stroop task. ⋯ This is probably the first study to explore the cerebral mechanism of current and remitted depression using the emotional Stroop task. RMD participants were also examined to explore whether attentional bias of emotional stimuli was a stable cognitive vulnerability factor that might be associated with the recurrence of depression. This study and would shed light on the cognitive bias of depression for emotional stimuli.

Clinical deep brain stimulation (DBS) systems typically utilize voltage-controlled stimulation and thus the voltage distribution generated in the brain can be affected by electrode impedance fluctuations. The goal of this study was to experimentally evaluate the theoretical advantages of using current-controlled pulse generators for DBS applications. ⋯ The use of current-controlled DBS may help minimize time-dependent changes in therapeutic efficacy that can complicate patient programming when using voltage-controlled DBS.

The aim of this single-blinded, complete crossover study was to evaluate the effects of tDCS on thermal and mechanical perception, as assessed by quantitative sensory testing (QST). ⋯ Impairment of these somatosensory percepts suggests a short-term suppression of lemniscal or suprathalamic sensory pathways following motor cortex stimulation by cathodal tDCS.

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.
