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

Electrophysiological Response to Executive Control Training in Autism
Susan Faja 
Fifty to 96% of children with ASD demonstrate impaired executive control the ability to manage complex or conflicting information in the service of a goal. Development of appropriate executive control is relevant to public health because these skills are critical for success in school, the workplace, and social relationships. Executive impairments in ASD have been well documented, but have received virtually no intervention research attention. Further, development of neural systems underlying executive control in ASD and their contribution to social function and symptoms remain poorly understood. The proposed project has the following scientific goals: (1) to determine the neural basis of executive control in children with ASD using two well-established electrophysiological measures (K99 period); (2) to test whether individual electrophysiological differences in executive control are meaningfully related to the social function and symptoms of children with ASD (R00 period); and (3) to assess whether brief, focused training in executive control produces significant changes in the brain function and behavior of children with ASD (R00 period). These goals will be addressed using a common set of electrophysiological measures. During the mentored K99 phase, the neural response to executive control tasks by 30 children with ASD will be compared with 30 typically developing children. During the independent phase, 60 children with ASD will be randomly assigned to receive brief executive control training or to a wait list. Individual differences in neural response and their relation to social ability will be assessed in all children prior to intervention.

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.
