α[C-11]Methyl-l-tryptophan (AMT) is an analog of tryptophan used with positron emission
tomography for the measurement of serotonin synthesis in humans. Several attempts have …

Positron emission tomography (PET) is now regularly used in the diagnosis and staging of
cancer. These uses and its ability to monitor treatment response would be aided by the …

Purpose: We studied the relation between quantitative interictal subdural EEG data and visually
defined ictal subdural EEG findings in children with intractable neocortical epilepsy, and …

Based on reports of increased platelet serotonin in 30 to 50% of autistic subjects, abnormal
serotonergic neurotransmission may be important in the pathogenesis of autism. However, …

We examined the brain organization for language and auditory functions in five high-functioning
autistic and five normal adults, using [ 15 O]-water positron emission tomography (PET). …
