Abstract
The brain continuously integrates information from the two retina into a persistent 3D experience. In
many situations the brain is faced with situations with multiple, ambiguous, interpretations. When the
brain is confronted with these situations it will choose one of the possible interpretations. Surprisingly
this perceptual selection process occurs continuously throughout our daily lives, without any conscious
awareness that this is taking place. In the lab we can isolate this perceptual selection process and tap
into the subjects, subjective, perceptual state. This enables us to investigate different visual states
without changing the actual visual input and allows us to directly investigate the source of perceptual
selection.
In the current investigation we presented the subjects with ambiguous rotating random dot spheres.
Using a 7 Tesla MRI scanner we acquired images with a much higher temporal and spatial resolution
than is currently standard for fMRI’s. Earlier studies have shown many areas, ranging from occipital to
frontal area, involved in this selection process. Investigating these areas with a much higher temporal
resolution and a higher voxel size enables us to investigate what brain processes govern the inevitable
perceptual selection visual awareness undergoes.
