The Bible and scientific research seem to allow for something very close to that possibility.

Baker’s Evangelical Dictionary of Biblical Theology, states that: “Heart” occurs over one thousand times in the Bible, making it the most common anthropological term in the Scripture. It denotes a person’s center for both physical and emotional-intellectual-moral activities.

Modern neuroscience amplifies the Bible’s view of the heart-brain connection and reinforces its approach to humans as fully integrated beings. Neurologically, the heart is part of the central nervous system. It is connected to our brain through several neurologic and hormonal mechanisms, the most important of which is the vagal nerve which plays a key role in calming our flight or flight response and provides information to the brain crucial for social interaction.

In Chapter 6 of Your Faithful Brain Dr. Matheson explores in some detail what science has learned about the relationship of the heart and the brain. He says:

Neuroscience supports that your heart and your brain are intimately and purposely connected. Your heart and brain influence each other reciprocally to help maintain emotional and physiological balance. Links between our brain and heart are interactive, providing two-way communication. This helps the heart participate with the brain in guiding our lives. One way to look at this is that your heart helps your brain think.
