Abstract
The maturation of the spiral ganglion and its peripheral pathways to the cochlea has been morphologically analysed from birth to the 14th day postnatally, i.e. to the time from the onset and during the maturation of cochlear potentials (mouse). The spiral ganglion cells and the neurons between the ganglion and habenula perforata must attain myelination before action potentials can be elicited. Earlier observations that a certain maturation of the organ of Corti is a prerequisite for the development of electrophysiological potentials is probably only coincidental in time with the structural development of the ganglion and the neurons.
