Study Summary

Purpose: In this study, the investigators will delineate how brain network dynamics are modulated by experimentally induced elevated blood glucose levels and examine how glucose levels gate neuronal excitability measured by the response to TMS. Participants: Participants must be between the ages of 18 and 65 with no known diabetes, no known adverse reaction to finger prick blood draw, and no known neurological or psychiatric illness. Participants must have a body-mass index less than 30. Procedures: Participants will consume either a drink that contains 75 g of glucose or a placebo, and their response to TMS will be measured to examine the effect of glucose on motor cortex excitability.

Primary Outcome

Change in MEP over time to indicate changes in motor cortex excitability

Interventions

  • DEVICE Single-pulse TMS
