Registered outcomes3
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Neurochemical response to GABAergic stimulation. | Through study completion, an average of 2 years. | Comparing brain excitation-inhibition measures (i.e., glutamate and GABA) when the GABAergic system is activated by a single oral dose of the GABA-B drug Arbaclofen versus the placebo condition. |
| Secondary | Functional connectivity measures using resting state functional magnetic resonance imaging. | Through study completion, an average of 2 years. | Maps of functional connectivity will be obtained for each condition and compared between adults with and without ASD. |
| Secondary | Brain oscillations under sensory stimulation | Through study completion, an average of 2 years. | Brain oscillations and event-related potentials will be recorded during sensory stimulation using high density electroencephalography. |
