"Fig. 2. Camera lucida drawing of a spiny stratum lucidum neuron {CA3 Lucidum*} subjected to correlated light and electron microscopic analysis. Inset shows the position of the neuron in the slice. The arrow indicates the origin of the axon from the soma. The arrowhead indicates the axon collateral shown in Figure 3B. An open arrow marks the ascending axonal collateral shown in Figure 4A. Note the numerous, occasionally very long, spines on the dendrites. sl, stratum lucidum; sp, stratum pyramidale. Scale bar = 100 [micro]m."

I question axons in SL, but I'm okay with it if Charise is on board. I would have called these 00230. Given the extended SP, I think a very small portion of this arbor is in SL. - CLR 02/11/2015

I'm good with it. Let's add to v1.1 active! - GAA
