Emotional processing, p50 sensory gating, and social functioning in bipolar disorder.

Emotional processing has been reported to effect sensory gating as measured by the event-related potential known as P50. Because both P50 and emotional processing are dysfunctional in bipolar disorder (BD), we sought to investigate the impact that concurrent emotional processing has on sensory gating in this psychiatric population. P50 was recorded using a paired-click paradigm.

Delayed early face processing in bipolar disorder.

Bipolar disorder primarily encompasses mood symptom states of depression and mania separated by symptom-free euthymia, and patients also exhibit cognitive deficits that include face processing. However, there is minimal extant event-related potential (ERP) research investigating the time course of these impairments. The aim of the present study was to contribute to a greater understanding of the specific stages of face processing that are impaired in bipolar disorder.

Event-related potential correlates of inhibition in bipolar disorder.

Lack of inhibitory control is a commonly reported impairment in patients with bipolar disorder, however, there has been little research regarding the time course of inhibitory processes. Twenty-six participants (13 bipolar and 13 controls) completed an emotional go/no-go inhibition task while event-related potentials were recorded. Go minus no-go difference waves were computed to index response inhibition.

Neural correlates of emotional face processing in bipolar disorder: an event-related potential study.

Background: Behavioural and imaging studies report that individuals with bipolar disorder (BD) exhibit impairments in emotional face processing. However, few studies have studied the temporal characteristics of these impairments, and event-related potential (ERP) studies that investigate emotion perception in BD are rare. The aim of our study was to explore these processes as indexed by the face-specific P100 and N170 ERP components in a BD cohort.

Acquisition of the lateral inconsistency in involuntary behaviour of upper limbs in 12-year-old children during walking at moderate speed.

The aim of this work was to investigate possible lateralisation in the behaviour of periodic motion of the human upper limb, during normal walking at a comfortable speed of locomotion. Ten healthy pre-adolescent, strongly right-handed, 12-year-old males participated in the experiment. Participants were walking on a treadmill with a standardised velocity of 1.
