Vep latency: Sex and head size

Clinical Neurophysiology, 2006
To investigate whether differences in visual evoked potential (VEP) latencies in a large sample of healthy subjects are influenced by different head size or sex or both.Black-and-white pattern-reversal checkerboard VEPs at a frequency of 2c/deg. were recorded in a group of 54 normal subjects of both sexes (age 30.15+/-9.12 years).

Head Shape and Size of Newborn Infants

Developmental Medicine & Child Neurology, 1971
SUMMARYStudies of head shape and size in 55 newborn infants showed that all measurements of head size related equally well with gestational age and birthweight. Formulae were derived for calculating head circumference from measurements of anteroposterior, biparietal and cross‐sectional areas of the head; in this way spuriously large measurements of ...

Resurfacing head size and femoral fracture: Are registry conclusions on head size justified?

European Journal of Orthopaedic Surgery & Traumatology, 2015
Joint registries report that peri-prosthetic fractures are the most common reason for early revision of a hip resurfacing arthroplasty (HRA) and are twice as likely with small implant sizes. However, a national survey found peri-prosthetic fracture to be strongly associated with surgical accuracy. We therefore asked whether the force required to induce

Reduction in head size in patients with aspartylglucosaminuria

Acta Neurologica Scandinavica, 2005
To show that the head may shrink in adult patients with aspartylglucosaminuria (AGU), a neurodegenerative disease.The head circumference (HC) of 40 adult patients (age at baseline 15 to 47) was measured twice with an interval of 10 years. Of these 40, 21 aged 15-47 and 19 young patients aged 5-14 as well as 40 healthy controls underwent lateral ...

Intrauterine Rubella, Head Size, and Intellect

Pediatrics, 1975
The assumption that congenital rubella is commonly associated with microcephaly and mental retardation was examined. Among a rubella clinic population of 111 children, 92 children had vision sufficient to allow testing by the Leiter International Scale. The mean IQ for this group was 99.46 (SD, 19.5).

Familial variation of head size and adjustment for parental head circumference

The Journal of Pediatrics, 1980
Occipitofrontal head circumference was measured on 122 twin pairs, their spouses, and their children. These data indicate that approximately 50% of normal head size variation is familial. Because of the relationship between the head size of normal children and their parents, adjustment of a child's head size value by the average parental value permits ...

Brain size, head size, and intelligence quotient in monozygotic twins

Neurology, 1998
Many studies of monozygotic (MZ) twins have revealed evidence of genetic influences on intellectual functions and their derangement in certain neurologic and psychiatric diseases afflicting the forebrain. Relatively little is known about genetic influences on the size and shape of the human forebrain and its gross morphologic subdivisions.

DETERMINING LESION SIZE IN OSTEONECROSIS OF THE FEMORAL HEAD

The Journal of Bone and Joint Surgery-American Volume, 2006
Several studies have documented that the size of the osteonecrotic lesion in the femoral head is an essential parameter in determining prognosis and treatment. There are several methods currently available to measure lesion size, but no general agreement as to which is most useful.

Association between Head Circumference and Body Size

Hormone Research in Paediatrics, 2011
<i>Background/Aims:</i> Studies on the association between head circumference (HC) and height or weight have shown variable results. <i>Methods:</i> Using data from the Dutch nationwide survey performed in 1997 (n = 14,500), we calculated correlations for different ages, and fitted a regression model for the estimation of HC. HC

EFFECT OF ENHANCEMENT OF HEAD BOUNDARY ON HEAD SIZE AND SHAPE

Perceptual and Motor Skills, 1958
In a previous study an attempt was made to deal experimentally, from the viewpoint of sensory-tonic and developmental theory (3), with the problem area of self-perception, or more specifically, with the perception of one's own body or body parts (4). A fundamental assumption underlying the study was that the body serves a dual role.
