How can we get connectivity between large systems of neurons in vivo? Using stimulations of small ensembles and a statistical method called group testing, we show in our recent paper that this is now feasible even in networks of up to 10 thousand neurons: 10^8 connections!
A software platform for construction and orchestration of adaptive experiments. Improv has been used to analyze streaming two-photon calcium images in larval zebrafish in real time, and fit GLM models to infer weighted connections among neurons as the experiment is ongoing.
First observation of complex supercurrent flow in a four-terminal graphene Josephson junction, where we find an unusual coexistence of supercurrent and dissipative currents in the same location.
Research into the mechanisms of superconducting currents in the quantum Hall regime in two-dimensional graphene Josephson junctions.
