Hemispheric Asymmetry in Neuroscience

AIM OF THE STUDY: Reliable and valid evaluation of hand strength is important for determining the effectivity of treatment strategies and it is accepted that grip and pinch strength provide an objective index for the functional integrity of upper extremity. This study was designed to evaluate the grip and pinch streng…

Left-right asymmetries are most likely a universal feature of bilaterian nervous systems and may serve to increase neural capacity by specializing equivalent structures on left and right sides for distinct roles. However, little is known about how asymmetries are encoded within vertebrate neural circuits and how later…

Neglect patients bisect lines far rightward of center whereas normal subjects typically bisect lines with a slight leftward bias supporting a right hemisphere bias for attention allocation. We used fMRI to assess the brain regions related to this function in normals, using two complementary tasks. In the Landmark task…

OBJECT The aim of this study was to examine the arcuate (AF) and superior longitudinal fasciculi (SLF), which together form the dorsal language stream, using fiber dissection and diffusion imaging techniques in the human brain. METHODS Twenty-five formalin-fixed brains (50 hemispheres) and 3 adult cadaveric heads, pre…

Widespread use of mobile phones which are a major source of electromagnetic fields might affect living organisms. However, there has been no investigation concerning prenatal exposure to electromagnetic fields or their roles in the development of the pyramidal cells of the cornu ammonis in postnatal life. Two groups o…

The purpose of this study was to determine the possible morphometrical differences of the corpus callosum between professional musicians and non-musicians. Certain callosal dimensions and areas were measured in 20 professional musicians and compared with 20 age-, sex- and handedness-matched control group by using in v…

OBJECTIVE: To test the hypotheses that (1) there is no difference in mandibular asymmetry between the crossbite and normal side in a unilateral crossbite group (UCG) and between the right and left sides in a bilateral crossbite group (BCG) and a control group (CG); and (2) there is no significant difference in mandibu…

(1) Aim: The study aimed at assessing simple-reaction, recognition and cognitive-reaction times to visual stimuli among student athletes: boxing, gymnastics, taekwondo, judo, karate and wrestling, using computer games tests. (2) Methods: Our study involved 332 students and athletes. We applied three types of computer…
