Greater left frontal activation appears to be a measure of appetitive reactivity for desired stimuli, such as alcohol cues. However, inconsistencies in past research examining frontal asymmetry to appetitive stimuli suggest that individual differences strongly influence frontal asymmetry to appetitive stimuli. Because core personality systems of approach, avoidance, and supervisory control play...

abstractbackgroundline of treatment for management of hydrocephalus despite available new techniques andsystems of shunting. associated complications should be recognized and managed properly,but the most recognized complications are shunt obstruction which its prevalencethrough surgical approach is discussed here. two approaches (frontal and parietal) are usedto insert ventriculoperitoneal shu...

Gray's Reinforcement Sensitivity Theory (RST) asserts three core personality systems: the behavioral approach system (BAS), the fight-flight-freeze system (FFFS) and the revised behavioral inhibition system (r-BIS). Past models of frontal activity link greater relative left frontal activity with Carver and White's (1994) BAS scale and trait impulsivity and greater relative right frontal activit...

OBJECTIVE To determine how cortical compensation occurs in higher cognitive systems during the recovery phase of diffuse axonal injury (DAI). DESIGN 12 right-handed patients with a magnetic resonance imaging (MRI) lesion pattern compatible with pure DAI were identified. Pure DAI was defined as finding of traumatic microbleeds on T2*-weighted gradient-echo images in the absence of otherwise tr...

INTRODUCTION Computer-aided surgery (CAS) systems integrate endoscopic visualization with real-time localization based on preoperative imaging. One short-coming of the current systems is the lack of real-time, radiographic assessment of surgical changes. We describe the potential applications of xCAT, a new intraoperative mobile volume CT scanner and its utility in providing surgical navigation...

As an explicit organizing metaphor, memory aid, and conceptual framework, the prefrontal cortex may be viewed as a five-member 'Executive Committee,' as the prefrontal-control extensions of five sub-and-posterior-cortical systems: (1) the 'Perceiver' (dominant-right-hemisphere ventral-lateral prefrontal cortex--VL/PERC-PFC) is the frontal extension of the ventral perceptual stream (the VL/PERC ...

We address the pose mismatch problem which can occur in face verification systems that have only a single (frontal) face image available for training. In the framework of a Bayesian classifier based on mixtures of gaussians, the problem is tackled through extending each frontal face model with artificially synthesized models for non-frontal views. The synthesis methods are based on several impl...

Face recognition has established itself as an important subbranch of pattern recognition within the field of computer science. Many state-of-the-art systems have focused on the task of recognizing frontal views or images with just slight variations in head pose and facial expression of people. In this work we concentrate on two approaches to recognize profile views (90 degrees) with previous kn...

The paranasal sinuses and the mastoid air-cell systems are evaginations of the mucous membrane of the nasal and nasopharyngeal cavities . Separate theories regarding their pneumatization have been suggested. However, correlation studies between the two systems giving a possible clue to a common pneumatizing process have been few (1 , 2]. One hundred adult patients without ear disease and minima...
