How Imagination Activates the Brain: Science Reveals Shared Neural Pathways with Perception

A new study has revealed that the brain uses the same neurons to imagine objects as it does to see them, providing a biological explanation for why mental imagery can feel as vivid as real perception. The research, led by Cedars-Sinai Health Sciences University, found that 40% of the neurons activated when viewing a face or object fire in the exact same pattern when a person later imagines that same image from memory.

By recording the electrical activity of individual neurons in patients with implanted electrodes, researchers were able to decode the neural patterns associated with visual perception, and imagination. They focused on the fusiform gyrus, a high-level visual processing area known for its role in recognizing faces and objects. Using artificial intelligence to analyze the “language” of these neurons, the team could predict exactly what a person was imagining based solely on brain activity.

The study confirmed that the neural code for object recognition previously identified in primates is also present in humans, establishing a shared biological mechanism across species. This discovery helps explain why memories can feel so vivid and lifelike, as the brain essentially reactivates the same sensory pathways used during the original experience.
