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.
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 imaging reveals super-sparse responses to natural images in primate V1, which carry sufficient information for discrimination of the input natural images with high accuracy.
The combination of a new genetically encoded voltage indicator and fast two-photon imaging methods enables detection of rapid neural electrical activity in organotypic slice cultures and in living flies.
Two photon calcium imaging experiments show that excitatory and inhibitory neurons in the mouse superior colliculus are differentially modulated by the motion contrast between stimulus center and surround.
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.
A spatial analysis of auditory and non-auditory properties of excitatory and inhibitory neurons in the mouse dorsal inferior colliculus defines the border between the lateral and the dorsal cortex.
Simultaneous 2-photon imaging of striosomes and matrix in mice shows that striosomes preferentially encode reward-predicting cues whereas both striatal compartments demonstrate reward-related activity.
An optical microscopy approach with an ultra-large field of view but retained subcellular resolution allows simultaneous imaging of neural activity in widely dispersed brain regions.
