The question of how affective processing is organized in the brain is still a matter of controversial discussions. Based on previous initial evidence, several suggestions have been put forward regarding the involved brain areas: (a) right-lateralized dominance in emotional processing, (b) hemispheric dominance according to positive or negative valence, (c) one network for all emotional processi...

INTRODUCTION Color processing is a central component of mammalian vision. Gender-related differences of color processing revealed by non-invasive functional transcranial Doppler ultrasound suggested right hemisphere pattern for blue/yellow chromatic opponency by men, and a left hemisphere pattern by women. MATERIALS AND METHODS The present study measured the accumulation of [18F]fluorodeoxygl...

OBJECTIVES Language function is mainly located within the left hemisphere of the brain, especially in right-handed subjects. However, functional MRI (fMRI) has demonstrated changes of language organization in patients with left-sided perisylvian lesions to the right hemisphere. Because intracerebral lesions can impair fMRI, this study was designed to investigate human language plasticity with a...

The present study sought to explore the relationship between Iranian EFL teachers' brain dominance, teaching experience and their teaching style. The study population consisted of all EFL teachers of high schools in Shiraz holding a B.A degree, with the sample consisting of 100 participants recruited through convenience sampling. The study employed a descriptive correlational design. To collect...

introduction: emotional words in comparison with neutral words have different hemispheric specialization. it is assumed that the right hemisphere has a role in processing every kind of emotional word. the objective of the present study was the development of a persian version of the dichotic emotional word test and evaluate its validation among adult persian speakers.   materials and methods: t...

Schizophrenia is associated with an absence of the lateralizations that typify the human brain. Previous evidence emphasized structural changes, particularly reduced asymmetry in extension and surface of the planum temporale, although gross structural deviations occur only in a minority of patients. The present study describes an absence of lateralization on a robust functional measure that cha...

the aim of this research was to compare brain quadrant dominance between athletic and non-athletic students. for this purpose, 199 university students participating in sport olympiad summer 1391 were selected as the athletic sample and 162 students as the non-athletic samples using simple random sampling method. the hermann brain dominance instrument (hbdi) was used for data collection. the res...

background: pragmatics is appropriate use of language across a variety of social contexts  that  provides accurate interpretation   of   intentions.   the   occurrence    of   the right hemisphere lesions can interfere with pragmatic abilities, and particularly with the processing of nonliteral speech acts. methods: since the objective of this study was to assess different  aspects of pragmatic...

In patient studies, impairments of sense of body ownership have repeatedly been linked to right-hemispheric brain damage. To test whether a right-hemispheric dominance for sense of body ownership could also be observed in healthy adults, the rubber hand illusion was elicited on both hands of 21 left-handers and 22 right-handers. In this illusion, a participant's real hand is stroked while hidde...

OBJECTIVE The purpose of this study was to assess and compare cognitive functioning in adults with unilateral hemispheric injury due to either congenital damage or an ischemic event in young adulthood. METHOD Adults with cerebral palsy resulting from left hemispheric brain damage were compared with adults who had a unilateral stroke in either the left or the right hemisphere. Our primary inte...
