Initial Mlu Predicts The Relative Efficacy Of Two Grammatical Treatments In Preschoolers With Specific Language Impairments, Paul J. Yoder, Dennis L. Molfese, Elizabeth Gardner

Center for Brain, Biology, and Behavior: Faculty and Staff Publications

Purpose—We sought to confirm predictions based on past findings that pre-treatment mean length of utterance (MLU) would predict which of two grammatical treatments would best facilitate generalized and maintained grammatical development in preschoolers with specific language impairment (SLI).

Method—The participants were 57 preschoolers with specific language impairment (SLI). A randomized group experiment was used. The two grammatical treatments were Broad Target Recasts (BTR) and Milieu Language Teaching (MLT). MLU was assessed at Time 1 in two conversational language samples. Growth rate of productive grammar was quantified using growth curve modeling on the Index of Productive Syntax (IPSyn) from …

Interictal Magnetoencephalographic Findings Related With Surgical Outcomes In Lesional And Nonlesional Neocortical Epilepsy, Rui Zhang, Ting Wu, Yingying Wang, Hongyi Liu, Yuanjie Zou, Wen Liu, Jing Xiang, Chaoyong Xiao, Lu Yang, Zhen Fu

Center for Brain, Biology, and Behavior: Faculty and Staff Publications

Purpose: To investigate whether interictal magnetoencephalography (MEG) concordant with other techniques can predict surgical outcome in patients with lesional and nonlesional refractory neocortical epilepsy (NE).

Methods: 23 Patients with lesional NE and 20 patients with nonlesional NE were studied. MEG was recorded for all patients with a 275 channel whole-head system. Synthetic aperture magnetometry (SAM) with excess kurtosis (g2) and conventional Equivalent Current Dipole (ECD) were used for MEG data analysis. 27 Patients underwent long-term extraoperative intracranial video electroencephalography (iVEEG) monitoring. Surgical outcomes were assessed based on more than 1-year of post-surgical follow-up using Engel classification system.

Results: As we …

Neuromagnetic Measures Of Word Processing In Bilinguals And Monolinguals, Yingying Wang, Jing Xiang, Jennifer Vannest, Tom Holroyd, Daria Narmoneva, Paul Horn, Yinhong Liu, Douglas Rose, Ton Degrauw, Scott Holland

Objective: This study aimed to use magnetoencephalography (MEG) to examine the question of whether Mandarin-English bilingual speakers recruit the same cortical areas or develop distinct language-specific networks without overlaps for word processing.

Methods: Eight healthy Mandarin-English bilingual adults and eight healthy English monolingual adults were scanned while single-word paradigms were audio-visually presented.

Results: Our results showed significantly stronger beta-band power suppression in the right inferior parietal lobe (IPL) covering the supramarginal gyrus (BA 40) and angular gyrus (BA 39) for bilinguals when processing Mandarin versus English. Moreover, there were no significant differences between bilinguals and monolinguals in the left inferior …

Sleep Assessments In Healthy School-Aged Children Using Actigraphy: Concordance With Polysomnography, Karen Spruyt, David Gozal, Ehab Dayyat, Adrienne Roman, Dennis L. Molfese

Center for Brain, Biology, and Behavior: Faculty and Staff Publications

Actigraphic recordings (ACT) are widely used in school children as a less intrusive and more extended approach to evaluation of sleep problems. However, critical assessment of the validity and reliability of ACT against overnight polysomnography (NPSG) are unavailable. Thus, we explored the degree of concordance between NPSG and ACT in school-aged children to delineate potential ACT boundaries when interpreting pediatric sleep. Non-dominant wrist ACT was simultaneously recorded with NPSG in 149 healthy school-aged children (4.1 to 8.8 years old, 41.7% boys and 80.4% Caucasian) recruited from the community. Analyses were limited to the Actiware (MiniMitter-64) calculated parameters originating from 1-min …

Sleep Duration, Sleep Regularity, Body Weight, And Metabolic Homeostasis In School-Aged Children, Karen Spruyt, Dennis L. Molfese, David Gozal

Center for Brain, Biology, and Behavior: Faculty and Staff Publications

OBJECTIVE: The goal was to explore the effects of duration and regularity of sleep schedules on BMI and the impact on metabolic regulation in children.

METHODS: Sleep patterns of 308 community-recruited children 4 to 10 years of age were assessed with wrist actigraphs for 1 week in a cross-sectional study, along with BMI assessment. Fasting morning plasma levels of glucose, insulin, lipids, and high-sensitivity C-reactive protein also were measured for a subsample.

RESULTS: Children slept 8 hours per night, on average, regardless of their weight categorization. A nonlinear trend between sleep and weight emerged. For obese children, …

Sleep Estimates In Children: Parental Versus Actigraphic Assessments, Ehab A. Dayyat, Karen Spruyt, Dennis L. Molfese, David Gozal

Center for Brain, Biology, and Behavior: Faculty and Staff Publications

Background: In the context of increasing awareness about the need for assessment of sleep duration in community and clinical settings, the use of questionnaire-based tools may be fraught with reporter bias. Conversely, actigraphy provides objective assessments of sleep patterns. In this study, we aimed to determine the potential discrepancies between parentally-based sleep logs and concurrent actigraphic recordings in children over a one-week period.

Methods: We studied 327 children aged 3–10 years, and included otherwise healthy, nonsnoring children from the community who were reported by their parents to be nonsnorers and had normal polysomnography, habitually-snoring children from the community …

Minimal Information For Neural Electromagnetic Ontologies (Minemo): A Standards-Compliant Method For Analysis And Integration Of Event-Related Potentials (Erp) Data, Gwen Frishkoff, Jason Sydes, Kurt Mueller, Tim Curran, John F. Connolly, Kerry Kilborn, Dennis L. Molfese, Charles Perfetti, Allen D. Malony

Center for Brain, Biology, and Behavior: Faculty and Staff Publications

We present MINEMO (Minimal Information for Neural ElectroMagnetic Ontologies), a checklist for the description of event-related potentials (ERP) studies. MINEMO extends MINI (Minimal Information for Neuroscience Investigations)to the ERP domain. Checklist terms are explicated in NEMO, a formal ontology that is designed to support ERP data sharing and integration. MINEMO is also linked to an ERP database and web application (the NEMO portal). Users upload their data and enter MINEMO information through the portal. The database then stores these entries in RDF (Resource Description Framework), along with summary metrics, i.e., spatial and temporal metadata. Together these spatial, temporal, and functional …
