background and aim: auditory temporal resolution skill is calculated according to the minimum required time to analyze or integrate acoustic events. this skill, which is essential for speech perception, was evaluated by gap detection tests. the aim of this study was to determine the presence or absence of any differences between the right and left ear in the gap detection test. methods: after p...

Previous research supported that the prevalence of addiction is related to brain laterality. Brain laterality is often determined by left/right handedness and this phenomenon is considered as an important factor in addiction prevalence. The present study attempts to examine the relationships between left/right handedness with addiction and smoking on Iranian population. In this study, 2000 male...

Migraine is a common disabling condition likely to be associated with dysfunction of brain pathways involved in pain and other sensory modalities. Functional brain imaging in acute migraine has proved challenging due to the logistic problems associated with an episodic condition although it has provided us with important insights into the pathophysiology of the condition. Since the seminal obse...

This study was designed to investigate differences in the degree of manual lateralization between right-handed and left-handed normal boys. Sixty-three 5, 7, and 9 year olds were tested on the Minnesota Rate of Manipulation Test (displacing subtest and turning subtest), the Finger Tapping Test, the Purdue Pegboard (placing subtest and assembly subtest), and the Southern California Motor Accurac...

BACKGROUND A right handed man with trauma to the head was admitted with headache and seizures. A severe right sided weakness was noted after a blunt trauma to the right side of his head. METHODS AND RESULTS MRI of brain revealed a right-sided subdural hematoma and a normal left hemisphere and downstream motor pathways. Bimanual simultaneous drawing and manual reaction times indicated that the...

introduction: pain as a complex process in the cns has been extensively studied by many researchers. it has been found that pain is controlled by certain pathways in the cns, one of most important of which is the descending noradrenergic system. the pathway begins with locus coeruleus (lc) nucleus and ends in the spinal cord. in this study, formalin test was used as a chemical and tonic pain te...

Relations between laterality and motor abilities were assessed in preschool children. Study sample included 202 children aged 5-7.5 decimal years. Upper extremity usage and gesture laterality was assessed by a battery of tests and used on children evaluation according to harmonious or inharmonious laterality. The performance of motor tasks that require whole body coordination, the speed of alte...
