Published Workflows
Objective: Enable simultaneous optical readout and manipulation of activity in neural circuits with single-neuron and single-action-potential precision.
Why it works: The approach combines genetically encoded activity sensors, optogenetic actuators, and advanced microscopies so that the same neurons can be both read out and manipulated using light, provided the components are sensitive enough and sufficiently cross talk free.
