Global Aphantasia
Global aphantasia is characterized by a complete absence of voluntary mental imagery across all sensory modalities - visual, auditory, tactile, taste, and smell. Sometimes referred to as 'total aphantasia.' This type of aphantasia differs from single-sensory aphantasia, offering unique insights into how the mind processes information without any form of mental simulation. Like other forms, global aphantasia can be either congenital (present from birth) or acquired. Understanding total aphantasia helps researchers explore the interconnected nature of sensory processing and memory systems. On this page, you'll find studies examining the full spectrum of sensory imagery, personal experiences of living with global aphantasia, and resources about adapting to a life without any form of mental imagery.

Same Brain, Different Reality: The Neuroscience Behind Aphantasia's Hidden Mechanisms
How a neurologist's decades-long investigation into patients who couldn't "see" half their memories led to groundbreaking discoveries about aphantasia, brain connectivity, and the hidden mechanisms of human imagination.

Breaking the Connectivity Code: How The Aphantasia Brain Access Visual Information Without the Mind's Eye
How a brain researcher's journey from engineering to neuroscience uncovered the hidden networks that allow people with aphantasia to navigate a visual world without mental imagery—and what this reveals about the nature of consciousness itself.
