Quantitative experiments and analysis determine the limit of excitation power of 1300-nm three-photon microscopy, and the imaging depth where three-photon outperforms two-photon for calcium imaging in the mouse brain.
Establishment of two-photon imaging with a 1100-nm laser, which underfills the objective's back aperture, detects activity of multiple neurons in the prelimbic area and hippocampal CA1 region of the intact mouse brain.
CaImAn is an open-software package that equips the neuroscience community with a set of turnkey, fast and scalable solutions to pre-processing problems arising in single cell calcium imaging data analysis.
The A1 of ferrets and mice show similar tonotopic organizations, with neurons preferring a single frequency being more precisely organized into a tonotopic map than multipeaked neurons.
Simultaneous calcium imaging and cell-attached recording in GCaMP6 transgenic mice in vivo reveals spiking-fluorescence relationship that supports more refined inference of neuronal activities from calcium imaging data.
Simultaneous voltage and calcium two-photon imaging of Purkinje neuron dendrites in awake mice reveals multiple interplaying mechanisms underlying sensory-evoked dendritic coincidence detection of parallel fiber and climbing fiber input.
An all-optical 3D two-photon imaging and photostimulation platform was demonstrated, with the capability to precisely stimulate a large group of cells in mice cortex in vivo with low laser power.
Two-photon in vivo calcium imaging reveals short time-scale, synchronous and sparse population activity in dentate gyrus that replays place-related information, and is important for formation of dentate-dependent spatial memory.
Curvature-preferring neurons in monkey V4 cluster into 0.5-mm patches, which highlights the importance of curvature detection in visual object recognition and the key functional role of V4 in this process.
