Official title

Modulation of Motor Cortex Excitability by Glucose Administration

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

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.
