Tools that allow acute and selective silencing of synaptic transmission in vivo would be invaluable for understanding the basis specific behaviors. Here, we show presynaptic expression proton pump archaerhodopsin enables robust, selective, reversible optogenetic with rapid onset offset. Two-photon fluorescence imaging revealed this effect is accompanied by a transient increase pH restricted to archaerhodopsin-expressing boutons. Crucially, clamping intracellular abolished without affecting...
Ecological speciation assumes reproductive isolation to be the product of ecologically based divergent selection. Beside natural selection, sexual selection via phenotype-assortative mating is thought promote isolation. Using neotropical fish Poecilia mexicana from a system that has been described undergo incipient ecological in adjacent, but habitats characterized by presence or absence toxic H 2 S and darkness cave habitats, we demonstrate gradual change male body colouration along...
Processing of complex signals in the hearing organ remains poorly understood. This paper aims to contribute this topic by presenting investigations on mechanical and neuronal response tropical bushcricket species Mecopoda elongata simple pure tone as well conspecific song a acoustic signal. The high-frequency bushcrickets, crista acustica (CA), is tonotopically tuned frequencies between about 4 70 kHz. Laser Doppler vibrometer measurements revealed strong dominant low-frequency-induced...
Previous in-vivo studies have shown that the tonotopically-organized hearing organ, crista acustica, of bushcricket Mecopoda elongata is a promising model for investigations basic mechanics. This linearly arranged organ with length <1 mm consists about 45 receptor units and processes frequencies from 4 up to at least 80 kHz. Pure-tone stimulation acustica leads travelling waves along longitudinal axis organ. We found amplitude maximum sound-induced shifted in radial direction during...
