11.11.2011 Attention and awareness uncoupled

Bi-stable visual stimuli used for awareness studies. Left diagram shows a classical example, the Necker cube, where the surface depth perception switches over time. On the right, a binocular rivalry stimulus is shown. By putting one grating in one eye and the other grating in the other eye, our percept starts to switch between the two gratings. Interestingly, as in our main stimuli, the unpatterned donut region also takes over the left grating when the right stimulus is perceived. They are ideal and widely used tools to investigate the neural correlate of visual awareness because our percept switches while the physical stimulus remains constant. Graphics: MPI for Biological Cybernetics Measuring BOLD activity exclusively from the target region. Low-level visual areas such as the primary visual cortex shows retinotopy, where adjacent points in the visual field correspond to adjacent points in the brain. Functional magnetic resonance imaging has high enough spatial resolution to take advantage of this property and measure blood-oxygen-level-dependent (BOLD) signal from regions of the primary visual cortex which corresponds to the “unpatterned inner hole inside the donut” in the right-eye stimulus. This made it possible for us to extract BOLD signal arising exclusively from the physically constant target visual stimulus (a part of the left grating which matches the “inner hole of the donut”), while the target became perceptually visible or invisible depending on the contextual configuration.

18.10.2011 Simple nerve cells regulate swimming depth of marine plankton

In the nervous system of Platynereis (white) some different neuropeptides have been discovered. They are stained in different colors. Image: Albina Asadulina and Markus Conzelmann, Group of Gáspár Jékely/MPI for Developmental Biology Microscopic image of the larva of the marine annelid Platynereis. The larvae swim in the sea powered by a band of beating tiny hair-like structures, the ciliary band. Image: Markus Conzelmann, Group of Gáspár Jékely/MPI for Developmental Biology The larva of Platynereis has a simple nervous system (black). In some single sensory nerve cells a neuropeptide is stained (red). Image: Markus Conzelmann, Group of Gáspár Jékely/MPI for Developmental Biology
