The P3(00) event-related potential (ERP) was elicited in 20 left- and 20 normal right-handed young adult male subjects using a simple visual stimulus discrimination task. For left-compared to right-handed subjects, P3 amplitude was larger at anterior electrode sites for the target stimuli and larger overall for the novel visual stimuli; P3 latency was shorter for left-compared to right-handers for the target stimuli. The N1, P2, and N2 components demonstrated similar handedness effects. The relationships of ERP amplitude and handedness to anatomical variables and cognitive factors are discussed.

Extraversion and the Brain: A Coordinate-Based Meta-Analysis of Functional Brain Imaging Studies on Positive Affect.
J Evid Based Med

School of Teacher Education, Dali University, Dali, China.
Objective: Extraversion is a fundamental personality dimension that contributes to an individual's overall health and well-being. Many studies have examined the neural bases of extraversion but these results are inconsistent. This study adopted a meta-analysis approach to examine the brain activity correlates of extraversion by incorporating functional neuroimaging studies in the context of positive affect/emotional stimuli.

Background: Intervertebral disc degeneration (IVDD) is one of the main causes of chronic low back pain. The degenerative process is often initiated by an imbalance between catabolic and anabolic pathways. Despite the large socio-economic impact, the initiation and progress of disc degeneration are poorly understood.

Objective: To develop and evaluate instruments for measuring implicit associations of nursing home care providers with behaviours aimed at improving resident mood.
Method: Study 1 ( = 41) followed an iterative approach to develop two implicit association tasks measuring implicit attitude (positive versus negative valence) and motivation (wanting versus not wanting) regarding mood-improving behaviours, followed by an evaluation of the content validity for target stimuli representing these behaviours. In Study 2 ( = 230), the tasks were assessed for stimulus classification ease (accuracy and speed) and internal consistency.
Unveiling the link between chronic inflammation and cancer.

The highly nuanced transition from an inflammatory process to tumorigenesis is of great scientific interest. While it is well known that environmental stimuli can cause inflammation, less is known about the oncogenic modifications that chronic inflammation in the tissue microenvironment can bring about, as well as how these modifications can set off pro-tumorigenic processes. It is clear that no matter where the environmental factors come from, maintaining an inflammatory microenvironment encourages carcinogenesis.

Like humans and many other animal species, birds exhibit left-right asymmetries in certain behaviours due to differences in hemispheric brain functions. While the lateralization of sensory and motor functions is well established in birds, the potential lateralization of high-level executive control functions, such as volitional attention, remains unknown. Here, we demonstrate that carrion crows exhibit more pronounced volitional (endogenous) attention for stimuli monocularly viewed with the left eye and thus in the left visual hemifield.
