From retinotopic processing to nonretinotopic representation

Encoding of visual information in the brain is retinotopic: Neighboring points in the visual field are mapped onto neighboring photoreceptors in the retina, and these neighborhood relations are maintained in the early stages of cortical processing. However ...

Image reproduction with compensation of luminance adaptation

Mahmut Sami Arpa

We introduce an image reproduction model that retargets colors for printing purposes to ensure similar luminance perception under photopic and scotopic vision. Our model is based on the physiological functioning of the rod and cone cells in the retina in v ...

Parallel pathways from whisker and visual sensory cortices to distinct frontal regions of mouse neocortex

Carl Petersen, Varun Sreenivasan, Céline Matéo, Alexandros Kyriakatos

The spatial organization of mouse frontal cortex is poorly understood. Here, we used voltage-sensitive dye to image electrical activity in the dorsal cortex of awake head-restrained mice. Whisker-deflection evoked the earliest sensory response in a localiz ...

Selective electrical and optical neuromodulation of the central nervous system with conformable microfabricated implants

Amélie Anne Guex

Neuroprosthetic systems are designed to interface with the nervous system, for the replacement or restoration of damaged functions in the motor and/or sensory systems. In order to have an efficient communication with the nervous tissue leading to optimized ...

Retinotopic information is rendered invisible by non-retinotopic processing

Michael Herzog, Marc Michael Lauffs

Classically, stimuli are rendered unconscious by backward masking or binocular rivalry, where it is usually assumed that the mask or the stimulus in the contralateral eye suppress the target. Based, on the Ternus-Pikler display (http://lpsy.epfl.ch/researc ...

Local versus global and retinotopic versus non-retinotopic motion processing in schizophrenia

Michael Herzog, Maya Roinishvili, Marc Michael Lauffs

Schizophrenia impairs cognitive function as much as perception. For example, patients perceive global motion in random dot kinematograms less strongly, because the integration of the dots into a single Gestalt is complex (e.g., Chen, Nakayama, Levy, Matthy ...

A computational model for reference-frame synthesis with applications to motion perception

Michael Herzog, Aaron Michael Clarke

As discovered by the Gestaltists, in particular by Duncker, we often perceive motion to be within a non-retinotopic reference frame. For example, the motion of a reflector on a bicycle appears to be circular, whereas, it traces out a cycloidal path with re ...

Local versus global and retinotopic versus non-retinotopic motion processing in schizophrenia patients

Michael Herzog, Maya Roinishvili, Marc Michael Lauffs

Schizophrenia impairs cognitive functions as much as perception. For example, patients perceive global motion in random dot kinematograms less strongly, because, as it is argued, the integration of the dots into a single Gestalt is complex and therefore de ...

Retina Color-Opponency Based Pursuit Implemented Through Spiking Neural Networks in the Neurorobotics Platform

Marc-Oliver Gewaltig, Egidio Falotico, Lorenzo Vannucci, Paul Levi, Georg Hinkel, Stefan Ulbrich, Alessandro Ambrosano, Ugo Albanese, Murat Kirtay

The 'red-green' pathway of the retina is classically recognized as one of the retinal mechanisms allowing humans to gather color information from light, by combining information from L-cones and M-cones in an opponent way. The precise retinal circuitry tha ...

Putting low-level vision into global context: Why vision cannot be reduced to basic circuits

Michael Herzog, Yvonne Evelina Thunell

To cope with the complexity of vision, most models in neuroscience and computer vision are of hierarchical and feedforward nature. Low-level vision, such as edge and motion detection, is explained by basic low-level neural circuits, whose outputs serve as ...
