Wie das Gehirn aus Lichtreizen Bildeindrücke konstruiert

1,55 Mio. Euro für Deutsch-Israelisches Kooperationsprojekt
RUB-Neurowissenschaftler koordiniert Forschungsvorhaben auf deutscher Seite

Wie konstruiert unser Gehirn aus den mannigfaltigen Lichtreizen, die auf das Auge treffen, ein robustes Bild? Bei diesem komplexen Ablauf sind weit verzweigte Netzwerke von Nervenzellen im Einsatz, deren Zusammenwirken Forscher aus Deutschland und Israel in einem neuen Kooperationsprojekt ergründen.

NeuroImage: Multiplexing in the visual brain

Nerve cell networks transform different information into overlaid activity patterns
RUB Scientists visualize for the first time simultaneous encoding of object orientation and its motion

Imagine sitting in a train at the railway station looking outside: Without analyzing the relative motion of object contours across many different locations at the same time, it is often difficult to decide whether it’s your train that starts moving, or the one at the opposite track.

Perception of motion

The appearance of a spot of light on the retina causes sudden activation of millions of neurons in the brain within tenths of milliseconds.

Nerve cells provide neighborly aid

The visual cortex of the brain analyzes and processes neuronal signals originating from the retina. When parts of the retina are injured, the corresponding regions in the visual cortex no longer receive any input signals.

After retinal lesions, the affected cortical neurons are suddenly cut off from their normal outside world input signals.
