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...

We aimed to compare Gleason score and tumor laterality between transrectal ultrasound-guided biopsy of the prostate (TRUSBX) and radical prostatectomy (RP). Some factors that could cause a discrepancy in results between these two procedures were also evaluated. Among the 318 cases reviewed, 191 cases were selected for inclusion in this comparative study. We divided the patients into two groups ...

During zebrafish development, the left-right (LR) asymmetric signals are first established around the Kupffer’s vesicle (KV), a ciliated organ generating directional fluid flow. Then, LR asymmetry is conveyed and stabilized in the lateral plate mesoderm (LPM). Although numerous molecules and signaling pathways are involved in controlling LR asymmetry, mechanistic difference and concordance betw...

Language laterality can be unequivocally ascertained by comparing the effects of unilateral ECT to the right and the left hemisphere. It has been shown in right-handed depressed patients that a unilateral treatment to the left hemisphere resulted in transient dysphasia whereas unilateral ECT to the right hemisphere did not. The language laterality in a small group of left-handed depressed patie...

Effects of human laterality, type of computer and noise on computer operators' performance of a data entry task were investigated. Seven right- and 7 left-motorsided male subjects performed the task on desktop and laptop computers in a sitting posture under varying noise levels. The mean number of characters entered per minute was statistically analysed. The right-motorsided operators entered m...

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...

BACKGROUND AND PURPOSE Language is a cardinal function that makes human unique. Preservation of language function poses a great challenge for surgeons during resection. The aim of the study was to assess the efficacy of resting-state fMRI in the lateralization of language function in healthy subjects to permit its further testing in patients who are unable to perform task-based fMRI. MATERIAL...

Electro-enccphalographic (E.E.G.) pattern of 35 drug free schizophrenic patients was studied. 15 cases (42.86%) had abnormal EEG records, 9 records out of 15 abnormal records showed effect of laterality. Laterality of abnormality to left hemisphers was present in 7 cases while laterality to right hemisphere was present only in 2 cases. Cortical locations of abnormalities were also studied. The ...
