People with aphantasia exhibit the inability to voluntarily generate or form mental imagery in their minds. Since term “aphantasia” was proposed describe this, it has gained increasing attention from psychiatrists, neuroscientists, and clinicians. Previous studies have mainly focused on definition, prevalence, measurement of aphantasia, its impacts individuals’ cognitive emotional processing, theoretical frameworks synthesizing existing findings, which contributed greatly our understanding aphantasia. However, there are still some debates regarding conclusions derived research theories that were constructed various sources evidence. Building upon endeavors, this systematic review emphasizes future is much needed refine definition diagnosis strengthen empirical investigations at behavioral neural levels, and, more importantly, develop update theories. These multiple lines efforts could lead a deeper further guide researchers directions.

Abstract The ability of the human brain to encode and recognize sequential information from different sensory modalities is key memory formation. sequence in which these are presented during encoding critically affects recognition. This study investigates modality sequences its neural impact on recognition using multivariate pattern analysis (MVPA) oscillatory EEG activity. We examined reinstatement multisensory episode-specific n = 32 participants who encoded sound-image associations (e.g., image a ship with sound frog). Images sounds were natural scenes 2-second real-life sounds, sequentially encoding. During recognition, stimulus pairs simultaneously, classification was used test whether order could be decoded as contextual feature memory. Oscillatory results identified distinct signature successful retrieval, associated original sequence. Furthermore, MVPA successfully patterns sequences, hinting at specific traces. These findings suggest that forms signature, affecting later provides novel insights into relationship between broad implications for cognitive neuroscience research.

Abstract Vividness of visual imagery is subject to individual variability, a phenomenon with largely unexplored neurobiological underpinnings. By analyzing data from 273 participants we explored the link between structural-functional organization brain connectomes and reported intensity (measured VVIQ-2). Employing graph theory analyses investigated both structural (DTI) functional (rs-fMRI) within network regions often implicated in imagery. Our results indicate relationship increased local efficiency clustering coefficients connectome individuals who experience more vivid Increased were mirrored increases left inferior temporal regions, region frequently identified as critical hub literature. Furthermore, found have lower levels global their connectome. We propose that clarity are optimized by characterized heightened localized information transfer interconnectedness. Conversely, an excessively globally integrated might dilute specific neural activity crucial for generating images, leading less locally concentrated resource allocation key involved vividness.

Adam Zeman’s recent review provides a thorough exploration of mental imagery extremes and their far-reaching implications. The article contrasts the lack subjective experience found in aphantasia with heightened vividness hyperphantasia. This discussion is extremely important for understanding diversity human thought from basic perspective high-level cognitive processes. To facilitate this conversation, we propose refined definitions that distinguish aspects experiences measurable performance. By addressing concern, both piece across broader field, encourage clearer imagery’s complexity emphasize need robust, multifaceted metrics separate experiential dimensions empirical. We hope will investigations neural, behavioral, psychophysiological mechanisms underlying extremes.
