In the classic model of vision, processing is local, feedforward and hierarchical. The first stages of the visual system are retinotopic, i.e., neighboring points in the outside world are mapped onto neighboring photoreceptors of the retina and this is pre ...
Activation of the basal forebrain (BF) has been associated with increased attention, arousal, and a heightened cortical representation of the external world. In addition, BF has been implicated in the regulation of the default mode network (DMN) and associ ...

Visual processing starts with retinotopic encoding: neighboring points in the real world are projected onto neighboring points in the retina. However, perception is usually non-retinotopic. For example, the motion trajectory of a reflector on a bike appear ...

The early visual system is organized retinotopically. However, under ecological viewing conditions, motion perception occurs in non-retinotopic coordinates. Even though many studies revealed the central role of nonretinotopic processes, very little is know ...
The cerebellum is known to contain a double somatotopic body representation. While the anterior lobe body map has shown a robust somatotopic organization in previous fMRI studies, the representations in the posterior lobe have been more difficult to observ ...
The early visual system is organized retinotopically. However, motion perception occurs in non-retinotopic coordinates. Even though many perceptual studies revealed the central role of non-retinotopic processes, little is known about their neural correlate ...

Very little information is transferred across saccades. It is commonly thought that detailed vision starts mainly anew with each saccade. Here, we show that transsaccadic integration occurs even for very fine grained and unconscious information when object ...

External stimuli and tasks often elicit negative BOLD responses in various brain regions, and growing experimental evidence supports that these phenomena are functionally meaningful. In this work, the high sensitivity available at 7T was explored to map an ...

Retinal imaging is routinely used to provide information about vision health. Recent studies showed that retinal images can also provide information on general health (e.g. stress level), brain pathologies and attention. Depending on the target information ...
The visual system is composed of diverse cell types that encode distinct aspects of the visual scene and may form separate processing channels. Here we present further evidence for that hypothesis whereby functional cell groups in the dorsal lateral genicu ...
