Recently, structural MRI studies in children have been used to examine relations between brain volume and behavioral measures. However, most of these studies have been done in children older than 2 years of age. Obtaining volumetric measures in infants is considerably more difficult, as structures are less well defined and largely unmyelinated, making(More)
Arterial spin labeled (ASL) perfusion MRI provides a noninvasive approach for longitudinal imaging of regional brain function in infants. In the present study, continuous ASL (CASL) perfusion MRI was carried out in normally developing 7- and 13-month-old infants while asleep without sedation. The 13-month infant group showed an increase (P<0.05) of relative(More)
Specific language impairment is a developmental language disorder characterized by failure to develop language normally in the absence of a specific cause. Previous twin studies have documented the heritability of reading and language measures as well as the genetic correlation between those measures. This paper presents results from an alternative to the(More)
The purpose of this study was to evaluate auditory sensory and discrimination responses in children with semi-lobar holoprosencephaly (HPE). Event-related potential (ERP) signals were recorded to tone pair stimuli at 62 electrode sites from the scalp using an oddball paradigm (a two-block design, inter-stimulus interval=70 or 300 ms; frequency of tone(More)
Converging information on medical issues, motor ability, and cognitive outcomes is essential when addressing long-term clinical management in children with holoprosencephaly. This study considered whether adding more informative structural indices to classic holoprosencephaly categories would increase prediction of cognitive outcomes. Forty-two children(More)
In this paper, different means of assessing cognitive development in children with severe impairments in both their expressive language and their motor skills are reviewed. A range of techniques are considered, including traditional cognitive tests and behavioral and physiological measures, but these techniques are generally impractical and minimally(More)
