How did early brain researchers describe the brain in terms of a nerve net? How does the idea of individual neurons differ from the idea of a nerve net?
The neuroectoderm appears along the length of the embryo and thickens to form the neural plate. The neural plate sinks and its edges thicken, forming a neural groove with a raised neural fold along each side. The neural folds then fuse along the midline beginning in the cervical region and progress toward the nose and tail. The lumen of the neural tube becomes a fluid-filled space that later develops into the central canal of the spinal cord and the ventricles of the brain. A hollow channel called the neural tube forms, which eventually will grow lateral processes that later form motor nerve fibers.
