They require optogenetic constructs and light-based control in an imaging-compatible setup. The abstract does not specify wavelengths, actuators, or target pathways.; requires optogenetic constructs and light-based experimental control alongside microscopy; Use requires genetic expression in optogenetically transduced neurons and an optical cell-control setup. Targeting is described as being based on promoter activity.; genetic transduction or expression of photosensitive ion channels or pumps is required; optical control infrastructure is required
The abstract does not specify which junctional mechanisms these probes can manipulate or what limitations they have in different systems. No named probe is given in the provided source text.; the abstract does not name specific optogenetic systems, targets, or operating constraints; The abstract does not show that optogenetic tools by themselves constitute established clinical therapies. It only supports preliminary proof-of-principle for therapeutic strategies.; requires genetic expression in optogenetically transduced neuronal populations; targeting is based on promoter activity
