New Model of Human Red Nucleus Figure 2. Distribution of WGA-HRP-labelled cells in mesodiencephalic structures (case 1). Successive serial sections are rostrally arranged, i.e., section A is the most rostral. The number in the left corner of each photomicrograph is the rostrocaudal distance (in micrometers) from section A. AM–anteromedian nucleus, dmpNr–dorsomedial part of parvicellular red nucleus, EW–Edinger-Westphal nucleus, FF–Field of Forel, FR–fasciculus retroflexus, MLF–medial longitudinal fasciculus, mNr–magnocellular red nucleus, MTN–medial terminal nucleus, NB–nucleus accessorius medialis of Bechterew, ND–nucleus of Darkschewitsch, Nint–interstitial nucleus of Cajal, Pf–parafascicular nucleus, riMLF–rostral interstitial nucleus of MLF, sPf– subparafascicular nucleus, sRF–suprarubral reticular formation, vlpNr–ventorlateral part of parvicellular red nucleus, III–oculomotor nucleus. Scale bar = 200 mm in P (also applies to A–O). doi:10.1371/journal.pone.0006623.g002 PLoS ONE | www.plosone.org 4 August 2009 | Volume 4 | Issue 8 | e6623
