View article: Oculomotor and Pupillary Markers of Visuospatial Mental Imagery in Aphantasia and Typical Imagery
Oculomotor and Pupillary Markers of Visuospatial Mental Imagery in Aphantasia and Typical Imagery Open
Our eyes engage not only in visual perception but also in visual mental imagery, mimicking perceptual processes without external stimuli. Mental imagery vividness varies along a spectrum, with aphantasia at the lower extreme, where individ…

Right-hemisphere frontoparietal oscillations precede conscious reports of visual targets Open
What neural events precede conscious reports? Hemisphere-asymmetric frontoparietal networks are causally related to conscious perception (Bartolomeo et al., 2025; Kaufmann et al., 2024), but their spectrotemporal dynamics remain unclear. H…

Visual mental imagery in typical imagers and in aphantasia: A millimeter-scale 7-T fMRI study Open
Most of us effortlessly describe visual objects, whether seen or remembered. Yet, around 4% of people report congenital aphantasia: they struggle to visualize objects despite being able to describe their visual appearance. What neural mech…

Probing the imaginable: Shared and Distinct Processes between Imagery and Perception across semantic domains Open
Our ability to visualize things outside our field of view feels similar to our visual perception. Yet, perception arises from real-world sensory experiences, while imagery depends on mental representations. This raises important questions …

Refining Visual Mental Imagery Research: Definitions, Metrics, and Key Research Areas. Comment on “Aphantasia and hyperphantasia: exploring imagery vividness extremes” Open
Adam Zeman’s recent review provides a thorough exploration of mental imagery extremes and their far-reaching implications. The article contrasts the lack of subjective imagery experience found in aphantasia with the heightened vividness of…

Developmental surface dyslexia and dysgraphia in a child with corpus callosum agenesis: an approach to diagnosis and treatment Open
We present a case study detailing cognitive performance, functional neuroimaging, and effects of a hypothesis-driven treatment in a 10-year-old girl diagnosed with complete, isolated corpus callosum agenesis. Despite having average overall…

Tracking the mind’s eyes: Spatiotemporal Dynamics of Domain-General and Domain-Specific Visual Mental Imagery Open
When we relive our memories, enjoy a novel, create a painting, or predict whether our car will fit in a parking spot, we use our “Mind’s Eye” to engage in Visual Mental Imagery (VMI). The current consensus is that VMI depends crucially on …

Development of a novel task to assess peripheral awareness in the presence of foveal distractors Open
Awareness of the visual periphery is a crucial aspect of perception. However, few studies assess the ability to detect peripheral stimuli while competing stimuli of the same type are simultaneously displayed in the center of the visual fie…

Fronto-parietal networks shape human conscious report through attention gain and reorienting Open
How do attention and consciousness interact in the human brain? Rival theories of consciousness disagree on the role of fronto-parietal attentional networks in conscious perception. We recorded neural activity from 727 intracerebral contac…

<i>Present</i>: flexible neuroscience- and technology-driven frameworks for the study of classroom engagement Open
Classroom engagement’s impact on academic success is crucial. However, the contributions of affective, cognitive, and behavioral components of engagement remain uncertain. We conducted two studies using non-invasive, research-based approac…

Visual mental imagery: evidence for a heterarchical neural architecture Open
Theories of Visual Mental Imagery (VMI) emphasize the processes of retrieval, modification, and recombination of sensory information from long-term memory. Yet, only few studies have focused on the behavioral mechanisms and neural correlat…

Resource sharing in cognitive control: Behavioral evidence and neural substrates Open
Cognitive control is a capacity-limited function responsible for the resolution of conflict among competing cognitive processes. However, whether cognitive control handles multiple concurrent requests through a single bottleneck or a resou…

Building a taxonomy of mental processes supporting social functioning to accelerate the integration between psychology and neuroscience: A commentary on Dang et al. Open
A methodological and theoretical chasm continues to exist between social psychology and social neuroscience, particularly with respect to research relevant to understanding racial bias, social justice and inequality. We use the Dang et al.…

Cognitive Considerations in Major Depression: Evaluating the Effects of Pharmacotherapy and ECT on Mood and Executive Control Deficits Open
Deficits in the executive control of attention greatly impact the quality of life of patients diagnosed with major depressive disorder (MDD). However, attentional deficits are often underemphasized in clinical contexts compared with mood-b…
