Context, circuit and modulation of courtship signal selection in Drosophila
(2023-03-23)Communication is multi-modal -- when we interact, we speak, gesticulate, and touch. However, the neural computations and circuits that select and coordinate these communication signals are unclear. We address this issue ... -
Mechanisms of local and global motion detection in Drosophila
(2021-07-06)Visual motion is an essential cue for many sighted animals. This can either be caused by the movement of an object, or the relative movement of the entire world caused by self-motion of the animal. Accordingly, the brain ... -
Cellular stress induces RIS dependent sleep and ALA dependent sedation via EGF receptor signaling in Caenorhabditis elegans
(2019-07-15)Why do we sleep? This question is still unsolved, although sleep is such a fundamental behavioral state in all organism with a nervous system. Several physiological mechanisms, like memory consolidation, metabolic waste ... -
From hearing to singing:sensory to motor information processing in the grasshopper brain
(2016-08-02)Grasshoppers, and among them especially the species Chorthippus biguttulus, have been used as a model system to study the neuronal basis of acoustic behavior. Auditory neurons have been described from intracellular recordings. ... -
Vision, cortical maps and neuronal plasticity in Bassoon and PSD-95 mutant mice.
(2014-03-21)Bassoon mutant mice (Bsn-/-) display a striking loss of synaptic ribbons in photoreceptor terminals, which impairs signal transduction through the retina (Altrock et al., 2003; Specht et al., 2007). Therefore we assessed ... -
The modulation of synaptic transmission at the Calyx of Held synapse
(2011-07-05)Short-term plasticity is a fundamental property of all synapses but its underlying mechanisms remain to be elucidated. In this study, the functional role of the well-known second messenger, ...
