- Allocation: RandomizedIntervention Model: Crossover AssignmentIntervention Model Description: This study will follow a single-blind, crossover design wherein each participant will participate in all of the 4 possible treatment combinations (intranasal insulin or intranasal placebo, olanzapine or placebo) including: Intranasal placebo and placebo Intranasal placebo and olanzapine Intranasal insulin and placebo Intranasal insulin and olanzapine Masking: Double (Participant, Investigator)Masking Description: Participants will be masked to: Knowing whether they were assigned to the olanzapine or placebo conditions Knowing whether they were assigned to the intranasal insulin or intranasal placebo conditions. Investigators will only be masked to the randomization of placebo or olanzapine for the participants, but will know whether the participant receives intranasal insulin or intranasal placebo.Primary Purpose: Basic Science

The primary objective of the study is to examine whether a single dose of OLA given to young healthy volunteers during PECs can inhibit the activity of a central insulin stimulus (i.e, INI) to reduce endogenous glucose production. Secondarily, in an exploratory arm, this study seeks to examine whether a single dose of OLA can inhibit improvements associated with INI administration on specific cognitive domains (visuospatial, and verbal memory). Further, the study will also explore the effects of insulin and OLA on neurochemical and neurohemodynamic measures obtained through MRI imaging techniques. To accomplish these objectives, this study will have two separate and parallel arms - a metabolic PEC arm to study the primary hypothesis, and an MRI imaging and cognitive testing arm to study the two secondary hypotheses.
