Filter Cart

The Filter Cart provides a way to query and access data for which you may be interested.  There are multiple places to go query and Add to Filter Cart (Sometimes called Download).  

A few points related to the filter cart are important to understand with the NDA Query/Filter implementation: 

First, the filter cart is populated asyncronously.  So, when you add subjects, sometimes it may take a few minutes to populate.  You can continue to do other things during this time. 

When you are adding your first filter, all data associated with your query will be added to the filter cart (whether it be a collection, a concept, a study, a data structure/elment or subjects). Not all data available for the subjects selected will necessarily be displayed.  For example, if you select the NDA imaging structure image03, and further restrict that query to scan_type fMRI, only fMRI images will appear and only the image03 structure will be available.  However, if you want to see all of the clinical and phenotype, then select, "Find All Subject Data" to see all the data avaialble for those subjects.  

when a secord or third filter is applied, an AND condition is used to determine the subjects that are exist in all filters.  If the subject does not appear in any filter, that subjects data will be excluded from your filter cart. Given the sparcity of data in the NDA, it is possible for no subjects to appear across filters.  If that happens, clear your filter cart, and start over.  

The NDA is looking to enhance query/filtering.  Until additional tools become available, it is best to package more data than you need and then package and download the data and use other tools to further restrict and analyze the data.  If you have any questions on data access, are interested in using avaialble web services or need help accessing data, please contact us for assistance.

Selected Filters
No filters selected

The filters you have selected from various query interfaces will be stored here, in the 'Filter Cart'. The database will be queried using filters added to your 'Filter Cart', when multiple filters are defined, each will be executed using 'AND' logic, so with each filter that is applied the result set gets smaller.

From the 'Filter Cart' you can inspect each of the filters that have been defined, and you also have the option to remove filters. The 'Filter Cart' itself will display the number of filters applied along with the number of subjects that are identified by the combination of those filters. For example a GUID filter with two subjects, followed by a GUID filter for just one of those subjects would return only data for the subject that is in both GUID filters.

If you have a question about the filter cart, or underlying filters please contact the help desk at The NDA Help Desk

The neurophysiology of sensory processing and multisensory integration in ASD
Natalie Russo 
Sensory atypicalities represent a cardinal feature of Autism Spectrum Disorders (ASD) and have been established as the source of much behavioral aggression, frustration, and functional impairment over the course of the lifespan within this population[1-3]. Research in this area generally has been clinically focused, and limited to descriptions of the phenomena [4-8], although there are notable exceptions.These include a small number of psychophysics studies that report that, compared with neurotypical individuals, persons with ASD demonstrate a specific strength in their ability to detect small changes or differences between visual [9-14], auditory [15-21] and tactile stimuli [22-25]. In addition, emerging evidence from the basic neuroscience literature on distinguishing features of ASD highlights fundamental differences in the reliability of evoked responses to unisensory stimuli using fMRI [26], as well as differences in the timing [27, 28] and amount of multisensory integration [27, 29] using event related potentials (ERP). Although both perspectives have advanced our knowledge of the field, what has been missing from the current literatures but which is now the focus of this proposal, is an integrated perspective on sensory processing in ASD. The series of studies proposed seeks to a)characterize the neurophysiological underpinnings of enhanced sensory perception across sensory modalities in ASD, b) assess the impact of enhanced sensory perception on the ability to integrate inputs from multiple sensory modalities at the level of both behavior and brain, c) to trace how the sephenomenon unfold during development, d) to discern how attention shapes MSI in persons with an ASD, e) to ascertain if physiological indices of sensory processing and MSI can predict autistic symptomatology, and f) to determine if meaningful subgroups of individuals with ASD can be identified on the basis of the physiological and behavioral data. These goals will be addressed in 14 experiments in which the performance of individuals with an ASD (children and adults) will be compared to IQ- and age-matched typically developing children and adults. Children between the ages of 8 and 16 years, and adults age 18-30 will be tested to assess the developmental progression of sensory processing and MSI both in TD and ASD individuals from the school years into adulthood. By combining clinical (diagnostic, cognitive and behavioral) and experimental (psychophysics, reaction time, electrophysiology) methods to trace the development of sensory and multisensory processing and their relevance to clinical features of ASD, the proposed studies will yield evidence that is both clinically and functionally relevant. These findings may help identify physiological mechanisms that afford an integrated perspective on ASD and facilitate early objective diagnosis.

Associated Studies

Studies that have been defined using data from a Collection are important criteria to determine the value of data shared. The number of subjects column displays the counts from this Collection that are included in a Study, out of the total number of subjects in that study. The Data Use column represents whether or not the study is a primary analysis of the data or a secondary analysis. State indicates whether the study is private or shared with the research community.

Brief Report: Social Functioning Predicts Externalizing Problem Behaviors in Autism Spectrum Disorder.Individuals with ASD often display externalizing behaviors, which have been associated with lower quality of life in adulthood. Social difficulties have been hypothesized to underlie externalizing problems among individuals with ASD (Klin and Volkmar in Asperger Syndrome, 340-366, 2000), but this has never been tested empirically. We examined whether socialization abilities predicted externalizing problems assessed by parent report in a group of 29 individuals with ASD (age range 7-16 years) and 29 TD individuals matched for IQ, age, and gender. Socialization scores accounted for 50% of the variance in externalizing behaviors among individuals with ASD, but not in TD children. These findings have implications for intervention, and suggest that targeting social difficulties might provide a better means to addressing externalizing problems.32/32Primary AnalysisShared
