A comparative study has been made of the catalepsy-inducing and antiapomorphine effects of DD-3480, a new butyrophenone derivative, and haloperidol in monkeys. DD-3480 exhibited catalepsy-inducing effects in a dose-dependent manner at oral doses of 2.5-10 mg/kg. This effect was comparable to that of haloperidol, but its duration was shorter in DD-3480 than(More)

The time evolution of the histogram (number of pixels versus signal intensity) is used to calculate delta R2 parameters from dynamic contrast-enhanced magnetic resonance (MR) imaging of the brain. This method partially corrects for partial volume effects and is an improvement over the approach using the signal intensity as a function of time when(More)
