(A–C) Selected horizontal sections through the forebrain of a 43 mm larva of P. marinus , immunolabelled for DLL protein. (A/B) Note bilateral streams of DLL-positive neurons apparently invading the olfactory bulb and neighboring pallium, and massive labelling of the subpallium. (C) Section through the alar plate of secondary prosencephalon (SP) and diencephalic prosomeres (p1-p3), showing signal in the prethalamus (PTh; p3) and in the alar hypothalamus (SPV; SP). Note a gap separating the rostral (hp2) and caudal (hp1) SPV cell groups. The arrow in (B) points to the second layer of striatal DLL-ir cells. For abbreviations, see list. Bar ϭ 100 ␮ m.

... more caudal SPV derivatives may include homologs of the anterior hypothalamic nucleus, the posterior (ventral) entopeduncular nucleus and the prein- certal area (Puelles and Rubenstein, 2003;Puelles et al., 2007). Interestingly, the DLL-positive SPV observed in the larval lamprey appears clearly subdivided into rostral and caudal portions (Fig. 4C), consistently with the postulate of rostral (prepeduncular; hp2) and caudal (peduncular; hp1) prosomeric subdivisions of the hypothalamus in the pres- ent updated model. The SPV is continuous in other verte- brates studied (e.g., mouse, chick), though its two parts show a difference in dorsoventral dimension and thickness ...

Animals integrate the different senses to facilitate event-detection for navigation in their environment. In vertebrates, the optic tectum (superior colliculus) commands gaze shifts by synaptic integration of different sensory modalities. Recent works suggest that tectum can elaborate gaze reorientation commands on its own, rather than merely actin...
