Neurulation is the process of formation of neural tube or nerve cord.
When gastrulation ends the prospective neural plate aligns length-wise with the mid-dorsal region. Then neural plate creates the central nervous system including brain & spinal cord.
Alongside the edges of neural plate appears a pair of longitudinal ridges known as neural folds which meet in a semicircle anteriorly.
The neural folds and the median line fuse to form neural tube, enclosing the neural canal.
A short opening remains in the front of the neural tube for a short time through neuropore. After some time posteriorly it contacts with the archenteron by neurenteric canal. Finally the closed tubular neural tube later forms the brain and spinal cord.

Dear Student,
the process of Neurulation in a frog is a folding process in the vertebrate embryos which essentially manages the transformation of the neural plate into the neural tube. At this particular stage the embryo is termed as a neurula. In the primary neurulation, the neural plate creases creases inward until the edges come in contact and fuse.
