Figure 14. Brn3c neurons and their projections – summary.

Figure 14

Coronal plate maps of neuron projections in the Brn3cCre/WT; ROSA26tdTomato/WT mouse brain progressing towards the caudal direction from (a) to (e). Nuclei containing cell bodies are indicated in yellow and axonal projections are indicated in blue. Novel ‘Drury’ nucleus is outlined in green. (a) Ventral lateral geniculate nucleus, magnocellular part (VLGMC); dorsal lateral geniculate nucleus (DLG); lateral posterior thalamic nucleus, mediorostral part (LPMR); anterior pretectal nucleus, dorsal part (APTD); paraventricular thalamic nucleus, posterior part (PVP); lateral habenular nucleus (LHb); precommissural nucleus (PrC); periventricular fiber system (pv); optic tract (opt). (b) VLGMC; DLG; medial geniculate nucleus, dorsal part (MGD); medial geniculate nucleus, ventral part (MGV); APTD; anterior pretectal nucleus, ventral part (APTV); deep mesencephalic nucleus (DpMe); periaqueductal gray nucleus (PAG); posterior limitans thalamic nucleus (PLi); opt; zona incerta (ZI). (c) Commissure of the superior colliculus (csc); posterior pretectal nucleus (PPT); nucleus of the optic tract (OT); optic nerve layer of the superior colliculus (Op); zonal layer of the super colliculus (Zo); superficial gray layer of the superior colliculus (SuG); intermediate gray layer of the superior colliculus (InG); intermediate white layer of the superior colliculus (InWh); brachium of the superior colliculus (bsc); deep gray layer of the superior colliculus (DpG); deep white layer of the superior colliculus (DpWh); MGD; MGV; medical geniculate nucleus, medial part (MGM); APT; DpMe; PAG; interstitial nucleus of Cajal (InC); PLi; ZI. (d) Lateral PAG (LPAG); dorsolateral PAG (DLPAG); dorsomedial PAG (DMPAG); Zo; SuG; Op; InG; InWh; DpG; DpWh; bsc; brachium of the inferior colliculus (bic); nucleus of the brachium of the inferior colliculus (BIC); DpMe. (e) Ventrolateral PAG (VLPAG); LPAG; DLPAG; DMPAG; Zo; SuG; Op; InG; InWh; DpG; DpWh; external cortex of the inferior colliculus (ECIC); intercollicular nucleus (InCo); bic; BIC; lateral lemniscus (ll); cuneiform nucleus (CnF); mesencephalic trigeminal nucleus (Me5); pontine reticular nucleus, oral part (PnO); paralemniscal nucleus (PL); microcellular tegmental nucleus (MiTg); parabigeminal nucleus (PBG); epimicrocellular nucleus (Emi). (f) VLPAG; LPAG; DMPAG; dorsal cortex of the inferior colliculus (DCIC); ECIC; central nucleus of the inferior colliculus (CIC); Me5; CnF; mesencephalic trigeminal tract (me5); laterodorsal tegmental nucleus (LDTg); laterodorsal tegmental nucleus, ventral part (LDTgV); principal sensory trigeminal nucleus, dorsomedial part (Pr5DM); principal sensory trigeminal nucleus, ventrolateral part (Pr5VL); sensory root of the trigeminal nerve (s5); pontine reticular nucleus, caudal part (PnC). (g) spinal vestibular nucleus (SpVe); spinal trigeminal tract (sp5); gigantocellular reticular nucleus (Gi); gigantocellular reticular nucleus, ventral part (GiV); sensory trigeminal nucleus, interpolar part (Sp5I); dorsomedial spinal trigeminal nucleus (DMSp5); medial vestibular nucleus (MVe). Plate maps a–g are adapted from the stereotaxic mouse brain atlas , plate numbers 49, 55, 56, 64, 69, 73, and 87 in order (Paxinos, Franklin, & Franklin, 2001).
