TL;DR: This work demonstrates simultaneous functional imaging of neuronal activity at single-neuron resolution in an entire Caenorhabditis elegans and in larval zebrafish brain with high-speed volumetric calcium imaging.

TL;DR: A genetically encoded fluorescent voltage indicator is created, simultaneously optimizing its brightness and membrane localization using the authors' microscopy-guided cell-picking strategy, and is applicable in three model systems.

TL;DR: In this article, the performance of VCO-based ADCs in the presence of nonidealities such as jitter, nonlinearity, mismatch, and the metastability of D flip-flops is analyzed.

TL;DR: Soma-targeting of fluorescent calcium indicators facilitates usage of simple, powerful, one-photon methods for imaging neural calcium dynamics and reported fewer artifactual spikes from neuropil, an increased signal-to-noise ratio, and decreased artifactual correlation across neurons.

TL;DR: The proposed architecture provides bandpass function by time-interleaving first-order voltage-controlled-oscillator (VCO)-based ADCs, which has the advantage that its resolution is determined by the time resolution rather than the voltage resolution, thus making it attractive for future low-voltage CMOS processes.
