KCNC1 and fragile X syndrome: Fig. 3A shows how the relative levels of Kv3.1 change along this axis of the MNTB in published measurements made on normal-hearing rodents and compares these to data from studies in which Kv3.1 levels become uniform across the nucleus, either because of the onset of partial hearing loss [31] or in an animal model of Fragile-X Syndrome [29]. It also shows the relative gradients of KHT that were used in simulations.
