Imagination Revives Visual Neural Patterns

Research published on April 9, 2026, indicates that imagining an object can revive portions of the neural pattern the brain uses to see that object. By recording brain activity directly, scientists demonstrated that the processes of visual perception and visual imagination share a common neural basis.

This discovery builds upon the work of Doris Y. Tsao, PhD, of the University of California, Berkeley, who served as a co-senior author on the study. Tsao had previously identified the specific neural code for object recognition in nonhuman primates.

The current findings reveal that this same neural code is present in humans. According to the research, this shared code explains how the human brain is able to recreate images from memory during the process of visual imagination.

Similarities Between Perception and Imagination

The overlap between seeing and imagining has been a subject of ongoing study. Brain scan research published on May 24, 2023, found that seeing an object and imagining it evoke highly similar patterns of neural activity.

This similarity suggests that the brain utilizes the same cellular machinery to represent an object regardless of whether that object is physically present in the environment or is being recalled from memory.

However, the brain must still be able to differentiate between these two states. Reporting from Neuroscience News has explored how the brain distinguishes imagination from reality and the specific circumstances under which this distinction fails.

Neural Architecture and Brain Waves

Further research into the architecture of imagination has focused on the specific electrical activity of the brain. In a study published on August 20, 2024, Hiroshi Yamakawa and colleagues from the University of Tokyo and the Whole Brain Architecture Initiative used EEG analysis to examine these processes.

Their research indicated that certain brain waves appear to be specific to visual imagination. The study also looked at the anatomy of hierarchy within the brain, specifically examining feedforward and feedback pathways.

Uncertainties in Spontaneous Imagination

While the mechanisms for imagining specific objects are becoming clearer, other forms of imagination remain less understood. A paper published on November 1, 2023, by Riccardo Fesce and Roberto Gatti of Humanitas University noted that less is known about spontaneous, free visual imagination.

Fesce and Gatti highlighted that while certain networks in the resting brain can be identified as sustaining specific visuospatial operations, the drivers of free imagination are not as well-defined. These identified networks include those used for:

• Scene representation
• Self-visualization

The researchers noted that the brain continues to elaborate information even in the absence of external stimuli, but the exact circuits that drive spontaneous visual imagination continue to be a subject of investigation.
