TL;DR: A unified non- Convex SCCA model, based on seven non-convex functions, for unbiased estimation and stable feature selection simultaneously is designed and an efficient optimization algorithm is proposed, which obtains both higher correlation coefficients and better canonical loading patterns.
Journal ArticleDOI
Lateral asymmetries of tardive dyskinesia in schizophrenia
TL;DR: The current study was designed to assess the prevalence of asymmetric dyskinetic movements in a larger number of schizophrenic patients using quantitative electromechanical measures of TD as well as observer rating scales.
Journal ArticleDOI
Therapeutics for cognitive aging.

TL;DR: This review summarizes the scientific talks presented at the conference “Therapeutics for Cognitive Aging,” hosted by the New York Academy of Sciences and the Alzheimer's Drug Discovery Foundation on May 15, 2009, which tackled the many aspects of developing therapeutic interventions for cognitive impairment.

Rich Club Network Analysis Shows Distinct Patterns of Disruption in Frontotemporal Dementia and Alzheimer’s Disease
Madelaine Daianu,Neda Jahanshad,Julio E. Villalon-Reina,Mario F. Mendez,George Bartzokis,Elvira E. Jimenez,Aditi Joshi,Joseph P. Barsuglia,Paul M. Thompson +8 more
TL;DR: This work reconstructed structural brain connectivity networks to map connections between cortical regions and examined how bvFTD and EOAD disrupt the weighted 'rich club' - a network property where high-degree network nodes are more interconnected than expected by chance.
Journal ArticleDOI
Myelination and brain electrophysiology in healthy and schizophrenic individuals.
TL;DR: The ‘expanded’ neurodevelopmental model of schizophrenia (Bartzokis, 2002) was useful in reinterpreting well-established observations in the field of sleep research and brain electrophysiology and may prove useful in interpreting age-related as well as disease-related findings in the EEG literature.
