Global Aphantasia

Global aphantasia is a complete absence of voluntary imagery across every sense, sometimes called total aphantasia. It can be congenital or acquired.

Rethinking Mental Imagery: Why Scientists Had It Wrong (And Why That's Good News)

For decades, neuroscientists assumed they understood mental imagery. Then people with aphantasia proved them wrong—and changed the future of consciousness research.

A decade of aphantasia research – and still going!

A decade of research shows aphantasia is a heterogeneous condition with varying subtypes and preserved cognitive performance. This suggests that conscious visual imagery is not required for complex tasks like memory and spatial reasoning.

Definition: Aphantasia

Researchers define aphantasia as the absence of voluntary sensory imagery, often extending beyond vision to other modalities. This formal definition establishes a standardized framework for classifying multisensory and global imagery deficits.

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.

Proposal for a consistent definition of aphantasia and hyperphantasia: A response to Lambert and Sibley (2022) and Simner and Dance (2022)

Researchers propose defining aphantasia as the absence or reduction of voluntary sensory imagery across any modality. This unified terminology avoids a proliferation of new terms while acknowledging that imagery deficits can be specific or multisensory.
