The paper measures synaptic inputs onto superficial excitatory neurons in mouse primary visual cortex using two-photon optogenetic stimulation and finds that layer 4 excitatory neurons and somatostatin-neurons in layer 2/3 are the most common sources of input, with strong connections distributed across cells.

This study examines how muscarinic receptor activation affects spike-timing dependent plasticity at layer 2/3 synapses in mouse auditory cortex, showing suppression of tLTP and reduced calcium influx.
