X) has uncovered surprising neural activity in people with aphantasia—a condition where individuals report being unable to ...

Thanks to 7T fMRI, researchers from Paris Brain Institute and NeuroSpin, the CEA's neuroimaging center, are exploring the neural substrate of visual imagery at very high resolution for the first time.

"Our test, called the Imagination Perception Battery (BIP), is designed to assess the link between perception and mental imagery through the different visual qualities that enable a scene to be ...

These processes were even less defined in 2003, when an articulate and bright 60-year-old man walked into Adam Zeman’s office. Zeman, a neurologist at the universities of Edinburgh and Exeter who ...

The human visual system is a dominant part of the brain’s processes and navigation of the world. To better understand an aspect of this system, researchers from Drexel University’s College of Nursing ...

The most famous test is called the Vividness of Visual Imagery Questionnaire, created in 1973 to study the strength of mental imagery, long before aphantasia was named.

If you have imagery and you imagine looking into the sun, it turns out that your pupils constrict [as well]—and that doesn't happen in people with aphantasia,” Zeman explains, referring to a ...

A new screening tool for visual perception difficulties after stroke that takes just 15 minutes to complete could help improve diagnosis of visual perception problems common in stroke survivors ...
