Organometallic Ruthenium(II) Arene Compounds with Antiangiogenic Activity

Paul Joseph Dyson, Hubert van den Bergh, Georges Wagnières, Patrycja Nowak-Sliwinska, Angela Casini, Alexey Nazarov

The antimetastatic ruthenium (II) compounds [Ru(eta(6)-p-cymene)Cl-2(PTA)] (PTA = 1,3,5-triaza-7-phosphaadamantane) (RAPTA-C) and [Ru(eta(6)-toluene)Cl-2(PTA)] (RAPTA-T), as well as their analogues [Ru(eta(6)-p-cymene)Cl-2(DAPTA)] (DAPTA = (3,7-diacetyl-1, ...

The geometry of visual perception: Retinotopic and nonretinotopic representations in the human visual system

Michael Herzog

Geometry is closely linked to visual perception; yet, very little is known about the geometry of visual processing beyond early retinotopic organization. We present a variety of perceptual phenomena showing that a retinotopic representation is neither suff ...

A New Approach to Non-Retinotopic Processing

Marco Boi

At every moment, the image the world projects on our eyes undergoes rapid and dramatic changes due to the eye movements and to the motion of the objects. Surprisingly, we are not aware of these changes, experiencing the world as stable and constant. This a ...

Non-retinotopic feature integration decreases response-locked brain activity as revealed by electrical neuroimaging

Michael Herzog, Olaf Blanke, Gijs Plomp, Thomas Otto, Manuel Mercier

When presented with dynamic scenes, the brain integrates visual elements across space and time. Such non-retinotopic processing has been intensively studied from a psychophysical point of view, but little is known about the underlying neural processes. Her ...

A (fascinating) litmus test for human retino- vs. non-retinotopic processing

Michael Herzog, Thomas Otto, Marco Boi

In human vision, the optics of the eye map neighboring points of the environment onto neighboring photoreceptors in the retina. This retinotopic encoding principle is preserved in the early visual areas. Under normal viewing conditions, due to the motion o ...

Design and validation of a telemetrically drived implantable glaucoma drainage device

Adan Villamarin

Glaucoma is one of the leading cause of irreversible blindness in the world and it usually occurs when the pressure inside the eyes gradually rises, permanently damaging the optic nerve. Medications and filtering surgery are two possible therapies availabl ...

Diffusion spectrum magnetic resonance imaging (DSI) tractography of crossing fibers

Patric Hagmann, Van Jay Wedeen

MRI tractography is the mapping of neural fiber pathways based on diffusion MRI of tissue diffusion anisotropy. Tractography based on diffusion tensor imaging (DTI) cannot directly image multiple fiber orientations within a single voxel. To address this li ...

Fast-Marching Tractography for Connection Matrix (Fast-TraC)

Jean-Philippe Thiran, Reto Meuli, Patric Hagmann, Leila Cammoun, Xavier Gigandet

Although high angular resolution diffusion MRI techniques are able to solve multiple intra-voxel fiber orientations, the usual streamline Diffusion Spectrum Imaging (DSI) tractography algorithms present some limitations in their ability to map complex fibe ...

Perceptual grouping induces non-retinotopic feature attribution in human vision

Michael Herzog, Thomas Otto

The human visual system computes features of moving objects with high precision despite the fact that these features can change or blend into each other in the retinotopic image. Very little is known about how the human brain accomplishes this complex feat ...

Influence of tyrosinase levels on pigment accumulation in the retinal pigment epithelium and on the uncrossed retinal projection

Friedrich Beermann

To study the relationship among tyrosinase activity, melanin production, and the routing of retinal ganglion cell (RGC) axons at the optic chiasm, we analysed mice with varying doses of the tyrosinase gene. These include the dark-eyed albino (Tyrc44H), a r ...
