Discussion

fMRI study reveals distinct neural mechanisms for object representations related to visual imagery experience.

Key finding shows shared neural representations exist for object knowledge and sensory input variations.
Participants with and without visual imagery were analyzed using fMRI and machine learning techniques.
Distinct brain regions emerged for visual-structured and language-structured knowledge representations.
Results highlight that different neural mechanisms underlie visual imagery and object knowledge retrieval.

Tian et al. (2025) studied this question.
