Verbal, nonverbal, demographic, and eye-hand laterality measures were administered to a sample of 34 Navy recruits attending a remedial reading program and 53 recruits who were members of a regular recruit company. Verbal intelligence scores (as determined by the General Classification Test) differentiated best between the remediation and non-remediation groups. Race (being non-Caucasian) was a...

background: research into the role of neuroimaging in primary headaches such as tension type headache (tth) is ongoing. in the present study, we aim to evaluate the ability of neuroimaging to detect potential abnormalities in patients with new onset tth and normal neurological exam. materials and methods: in a prospective study, 294 cases of new onset tth with normal neurological exam, that had...

Over the last century, sporadic research has suggested that people whose hand, eye, foot, or ear dominances are not consistently right- or left-sided are at special risk of suffering academic difficulties. This phenomenon is known as crossed laterality. Although the bulk of this research dates from 1960's and 1970's, crossed laterality is becoming increasingly popular in the area of school educ...

More breast cancers are diagnosed in the left breast than the right. The ratio (l/r) is called the laterality ratio. We analyzed 1.2 million cases of breast cancer diagnosed in the US between 1973 and 2010 and recorded by the Surveillance, Epidemiology, and End Results (SEER) program. We found that the laterality ratio depends upon the country of birth, but not race of the patient. We identifie...

BACKGROUND AND PURPOSE Three-dimensional time-of-flight MR angiography (3D TOF MRA) often discloses prominent posterior cerebral artery (PCA) laterality in the setting of M1-segment middle cerebral artery (MCA) occlusion. We sought to analyze the implications of prominent PCA laterality at 3D TOF MRA. METHODS We retrospectively reviewed 3D TOF MRA and digital subtraction angiography (DSA) fin...

Despite significant scientific advances, the nature of the left-hemispheric systems involved in language (speech and gesture) and manual actions is still unclear. To date, investigations of human laterality focused mainly on non-communication functions. Although gestural laterality data have been published for infants and children, relatively little is known about laterality of human gestural c...

Introduction: about 20% to 30% of patients with epilepsy are diagnosed with drug-resistant epilepsy and one third of these are candidates for epilepsy surgery. Surgical resection of the epileptogenic tissue is a well-established method for treating patients with intractable focal epilepsy. Determining language laterality and locality is an important part of a comprehensive epilepsy program befo...
