Neural Representations in Visual and Parietal Cortex Differentiate between Imagined, Perceived, and Illusory Experiences.

Journal of Neuroscience September 20, 2023 Siyi Li, Xuemei Zeng, Zhujun Shao et al.

Humans constantly receive massive amounts of information, both perceived from the external environment and imagined from the internal world. To function properly, the brain needs to correctly identify the origin of information being processed. Recent work has suggested common neural substrates for perception and imagery. However, it has remained unclear how the brain differentiates between...

A cortical hierarchical mechanism for subjective visual experience during working memory

Tingting Wu, Qing Yu

Abstract Working memory (WM) provides a mental sketchpad for simulating sensory experiences associated with mnemonic content. A critical unresolved question is how the brain generates the subjective sensory experience of these internal simulations. Here, we studied individuals with aphantasia, who report a subjective inability to generate visual imagery despite normal WM performance, providing...
