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

Dysfunction of Sensory Inhibition in Autism
Richard Edden 
Autism Spectrum Disorder (ASD) is a group of developmental disorders which affects approximately 1% of children, a prevalence rate that is increasing annually. The molecular basis of ASD is likely to be complex and heterogeneous, but given the central role of the inhibitory neurotransmitter GABA incognitive control, development and plasticity and a growing body of evidence linking GABAergicdys function to autism and autistic phenotypes, GABA system is a strong potential area for ASD research.Recently, it has become possible to measure GABA concentration non-invasively in the brain using magnetic resonance spectroscopy (MRS), and in an extremely novel set of experiments we have shown that differences in regional GABA concentration among healthy subjects have measurable behavioral correlates. For example, GABA concentration in sensorimotor cortex correlates with performance at a somotosensory discrimination task (see paper attached and below); this may have particular relevance for autism, as atypical response to tactile stimuli is a common (and diagnostic) feature of autism and one that can substantially impair behavioral function This proposal arises from a collaboration between Dr Richard Edden (PI) and Dr Stewart Mostofsky (Co-I)to apply the extremely novel pairing of MRS of GABA with somatosensory paradigms to investigate whether there is a measurable GABA deficit in autism, and whether this correlates with autism associated differences in somatosensory processing. The findings from examination of GABA MRS and its association with autistic behavior will provide a foundation for investigating novel treatment therapies, specifically use of medications that increase GABAergic activity. In Aim 1, we will measure GABA concentration in a group of 32 typically developing children (TDC) between the age of 8 and 12 years to characterize the typical range. In Aim 2, we will compare twenty children with ASD to twenty TDC to investigate differences in GABAergic inhibition, and perform measures of tactile discrimination to investigate whether the abnormal tactile processing commonly observed in ASD arises from a GABAergic deficit.
