Axonal connections between the left and right sides of the brain are crucial for bilateral
integration of lateralized sensory, motor, and associative functions. Throughout vertebrate …

In vertebrate evolution, the brain exhibits both conserved and unique morphological features
in each animal group. Thus, the molecular program of nervous system development is …

The Pax6 gene plays a developmental role in various metazoans as the master regulatory
gene for eye patterning. Pax6 is also spatially regulated in particular regions of the neural …

Hox genes exert fundamental roles for proper regional specification along the main rostro-
caudal axis of animal embryos. They are generally expressed in restricted spatial domains …

The neural crest is a vertebrate-specific cell population that contributes to the facial skeleton
and other derivatives. We have performed focal DiI injection into the cranial neural tube of …

The structural organization of the lamprey extratelencephalic forebrain is re‐examined from
the perspective of the prosomeric segmental paradigm. The question asked was whether the …

The distribution of cholinergic neurons and fibers was studied immunohistochemically in the
brain of two species of lampreys (Petromyzon marinus and Lampetra fluviatilis), by using an …

Neural crest cells contribute extensively to vertebrate head morphogenesis and their origin
is an important question to address in understanding the evolution of the craniate head. The …

Lamprey, the living jawless vertebrate, has been regarded as one of the most primitive
groups of vertebrates. The evolutionary phylogenetic position of the lamprey promises to …

Organization and development of the early vertebrate hindbrain are controlled by a cascade
of regulatory interactions that govern the process of segmentation and patterning along the …
