   Sammanfattning : The vertebrate nervous system is a highly complex and intriguing structure with diverse functions. To understand the functional nervous system, we first have to be aware of how it is assembled during development. LÄS MER

   Sammanfattning : Cranial placodes are transient thickenings of the vertebrate embryonic head ectoderm that will give rise to sensory (olfactory, lens, and otic) and non-sensory (hypophyseal) components of the peripheral nervous system (PNS). In most vertebrate embryos, these four sensory placodes undergo invagination. LÄS MER
