Several important behavioral and anatomical effects were observed.
	First, all of the animals appeared to develop an aversion to the taste and/or subjective effects of the medications.
	Second, a significant number of monkeys became aggressive during the study
	(2/3 of the olanzapine recipients, 1/3 of the haloperidol recipients).
	Third, chronic exposure to haloperidol and olanzapine resulted in comparable and diffuse reductions in brain volume and brain weight.
