The surface area of human V1 predicts the subjective experience of object size
The surface area of human primary visual cortex (V1) varies substantially between individuals
for unknown reasons. We found that this variability was strongly and negatively correlated …

Unexpected arousal modulates the influence of sensory noise on confidence
10.7554/eLife.18103.001 Human perception is invariably accompanied by a graded feeling
of confidence that guides metacognitive awareness and decision-making. It is often …

[HTML][HTML] Relating inter-individual differences in metacognitive performance on different perceptual tasks
Human behavior depends on the ability to effectively introspect about our performance. For
simple perceptual decisions, this introspective or metacognitive ability varies substantially …

Stochastic resonance effects reveal the neural mechanisms of transcranial magnetic stimulation
Transcranial magnetic stimulation (TMS) is a popular method for studying causal relationships
between neural activity and behavior. However, its mode of action remains controversial, …

Visual working memory performance in aphantasia
C Jacobs, DS Schwarzkopf, J Silvanto - Cortex, 2018 - Elsevier
Aphantasia, ie, the congenital inability to experience voluntary mental imagery, offers a new
model for studying the functional role of mental imagery in (visual) cognition. However, until …

[PDF][PDF] Neural population tuning links visual cortical anatomy to human visual perception
The anatomy of cerebral cortex is characterized by two genetically independent variables,
cortical thickness and cortical surface area, that jointly determine cortical volume. It remains …

Contextual illusions reveal the limit of unconscious visual processing
The perception of even the most elementary features of the visual environment depends
strongly on their spatial context. In the study reported here, we asked at what level of abstraction …

[HTML][HTML] Subjective size perception depends on central visual cortical magnification in human V1
DS Schwarzkopf, G Rees - PloS one, 2013 - journals.plos.org
In the Ebbinghaus illusion, the context surrounding an object modulates its subjectively
perceived size. Previous work implicates human primary visual cortex (V1) as the neural …
