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.
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.
New methods in behavioural psychophysics (the binocular-rivalry technique) and brain imaging (decoding techniques) have been developed and utilized to uncover many new insights into the mechanisms and brain areas involved in mental imagery.
Performance in visual working memory can be predicted by the strength of mental imagery as assessed with binocular rivalry. Findings could help reconcile current controversy regarding the mechanism and location of visual mnemonic storage.
