Three-dimensional reconstruction of monosynaptically connected neuronal pairs of presynaptic pyramids and postsynaptic interneurons from groups of medium and wide arbor interneurons. a, Medium arbor basket cell.b, Dendrite-targeting cell. c, Wide arbor basket cell. Note that presynaptic pyramids (dendrites areorange, and axons are yellow) establish two and three putative synapses (white circles) on medium and wide arbor basket cells, respectively (dendrites arelight blue, and axons are darker blue).
