Two‐Photon Absorption and the Design of Two‐Photon Dyes
Angewandte Chemie - International Edition, 2009 AbstractTwo photons are better than one: This principle applies to a wide range of applications, ranging from engineering to physiology. Recent advances in our understanding of the phenomenon of two‐photon absorption (see picture) and in the design of two‐photon dyes are rapidly increasing the scope of this field.magnified imageTwo‐photon absorption ...

Sharp-wave ripple doublets induce complex dendritic spikes in parvalbumin interneurons in vivo
Nature Communications, 2022 The influence of sharp-wave ripples (SPW-Rs) on dendritic computation remains poorly understood. Here, the authors demonstrate the existence of SPW-R associated, branch-specific, dendritic spikes which serve as a temporal and spatial coincidence ...

An open-source pipeline for analysing changes in microglial morphology
Open Biology, 2021 Changes in microglial morphology are powerful indicators of the inflammatory state of the brain. Here, we provide an open-source microglia morphology analysis pipeline that first cleans and registers images of microglia, before extracting 62 parameters ...

3D optogenetic control of arteriole diameter in vivo
eLife, 2022 Modulation of brain arteriole diameter is critical for maintaining cerebral blood pressure and controlling regional hyperemia during neural activity. However, studies of hemodynamic function in health and disease have lacked a method to control arteriole

Quantitative analysis of 1300-nm three-photon calcium imaging in the mouse brain
eLife, 2020 1300 nm three-photon calcium imaging has emerged as a useful technique to allow calcium imaging in deep brain regions. Application to large-scale neural activity imaging entails a careful balance between recording fidelity and perturbation to the sample.

Multipath Entanglement of Two Photons [PDF]
Physical Review Letters, 2009 We present a novel optical device based on an integrated system of micro-lenses and single mode optical fibers. It allows to collect and direct into many modes two photons generated by spontaneous parametric down conversion. By this device multiqubit entangled states and/or multilevel qu-$d$it states of two photons, encoded in the longitudinal momentum
