The strength of a person’s mental imagery is linked to the excitability of different brain regions. Exactly how this network controls the strength of visual imagery remains unknown.

Insights into the neural mechanisms that underlie visual imagery, how imagery can be objectively and reliably measured, and how it affects general cognition.
Study using binocular rivalry and self-rated object and spatial imagery (VVIQ, SUIS and OSIQ) finds people with aphantasia show almost no imagery-based rivalry priming. Findings suggest aphantasia is a condition involving a lack of sensory and phenomenal imagery and not a lack of metacognition.
Mental imagery is a fundamental part of human cognition that bridges cognition with sensory representations. This paper introduces a novel technique to measure the sensory capacity of mental imagery while removing the need for memory and any direct subjective reports.
Visual working memory performance is assessed in aphantasic individual. Study finds while participant performs significantly worse than controls on the most difficult visual working memory trials, surprisingly, their performance on a task designed to involve mental imagery did not differ from controls.
