The ability to efficiently and reliably estimate the presence and magnitude of cortical synapses is critical to understanding how synaptic connectivity relates to neural computation, behaviour, and disease. Two-photon optogenetic stimulation paired with whole-cell electrophysiology allows for potential presynaptic partners to be tested for a given patched cell by measuring optogenetically evoked postsynaptic currents (PSCs). However, existing optogenetic mapping approaches fail to reach their potential for three critical reasons: (1) they rely on stimulating neurons one at a time, (2) they use
