Our Request for Applications to expand HCRN closed on August 1st and we received a robust response. Six high quality pediatric neurosurgery centers have applied to join HCRN! Any of these centers would make a significant contribution to the ongoing hydrocephalus research effort. The current HCRN investigators now have the task of reviewing and scoring these and selecting one or two to become fellow members of the Network. This magnitude of response is exciting and indicates the interest in hydrocephalus research and specifically HCRN work among the pediatric neurosurgeons.
