What Neuroscience Reveals About Aging, Dementia & God's Design with Dr. Robyn Honea

Can neuroscience strengthen your faith? In this thought-provoking episode of inContext, Michael Easley sits down with neuroscientist Dr. Robyn Honea, whose research has focused on Alzheimer's disease, brain imaging, and neuroplasticity for more than two decades. Together, they explore what modern neuroscience reveals about the incredible design of the human brain—and why our ultimate hope is found not in biohacking or longevity, but in Christ. Dr. Honea shares how years of studying the aging brain led her to publicly integrate her Christian faith with her scientific work. They discuss the fear of dementia, the promise and limitations of medical advances, the role of exercise and healthy habits in brain health, and why believers should steward their bodies without making health an idol. Whether you're caring for aging parents, interested in neuroscience, working in healthcare, or simply wondering how faith and science fit together, this conversation offers biblical wisdom, scientific insight, and lasting encouragement.
