Daily ultrastructural remodeling of clock neurons.

In about 250 clock neurons in the brain form a network that orchestrates circadian rhythmicity. Among them, eight small Lateral ventral Neurons (s-LNvs) play a critical role, synchronizing the circadian ensemble the neuropeptide Pigment-Dispersing Factor (PDF). Moreover, their neurites show daily variations in morphology, PDF levels, synaptic markers and connectivity.

Single Objective Light Sheet Microscopy allows high-resolution brain imaging of Drosophila.

imaging of dynamic sub-cellular brain structures in is key to understanding several phenomena in neuroscience. However, its implementation has been hindered by a trade-off between spatial resolution, speed, photobleaching, phototoxicity, and setup complexity required to access the specific target regions of the small brain of . Here, we present a single objective light-sheet microscope, customized for imaging of adult flies and optimized for maximum resolution.

The metronome-based methodology to monitor the stroke length changes in trained swimmers.

The aim of our study was to develop a methodology that uses the metronome to constrain the swimmers' stroke rate with the aim to monitor changes in stroke length (SL) during two different periods of the season. Thirteen young trained swimmers (15.7 ± 1.
