Research Summary

Current research explores the neural basis of the genetic vulnerability of children (ages 13 - 18 of alcoholics. Another project assesses the effects of marijuana on brain blood flow and cognition. Both research areas involve purely behavioral assessment of cognitive functions such as attention and memory, as well as neuroimaging studies performed during cognitive task performance. We are assessing blood flow with positron emission tomography (PET) during cognitive task performance in schizophrenic patients, normal volunteers, and marijuana users. O'Leary, D.S., R.I.
