    Insulin-induced hypoglycemia impairs cortical function, increasing reaction times in both healthy individuals and type 1 diabetics. Individual responses varied, with some showing no change despite low blood glucose levels.

    Area of Science:

    • Neuroscience
    • Endocrinology
    • Metabolic Disorders

    Background:

    • Insulin-induced hypoglycemia affects brain function.
    • Type 1 diabetes patients experience altered glucose regulation.

    Purpose of the Study:

    • To investigate cortical function during hypoglycemia.
    • To compare reaction times in healthy controls and type 1 diabetics.

    Main Methods:

    • Assessed reaction time to visual stimuli under euglycemic and hypoglycemic conditions.
    • Used intravenous insulin to induce controlled hypoglycemia.

    Main Results:

    • Hypoglycemia significantly increased reaction times in both groups.
    • Individual variability in response was observed.

  • Reaction time changes were not correlated with hormone responses.

    • Conclusions:

    • Cortical function, measured by reaction time, is impaired by hypoglycemia.
    • Significant individual differences exist in response to low blood glucose.
