title: Vernon remembered.
abstract: The world of neuroscience lost one of its pioneers when Vernon B. Mountcastle, M.D., died January 11 in Baltimore at age 96. Often referred to as "the father of neuroscience," Mountcastle defied early skeptics by showing how cylinders of neurons, dedicated to specific tasks, work together. This month's Cerebrum features remembrances from two colleagues influenced by Mountcastle-among the many who have gone on to make their own significant impacts in neuroscience.
