title: [The structural-functional organization of the auditory cortex in rats].
abstract: Using axonal transport of horseradish peroxidase and electrophysiological mapping technique, studies have been made on structural and functional organization of the auditory cortex in rats. After the injection of HRP to peripheral parts of the auditory cortex, mainly initial neurones were found in the dorsal and median parts of the geniculate body. Electrophysiological experiments revealed the localization of neurones with widespread frequency-threshold curves and high thresholds at characteristic frequency. On the basis of the data obtained, it is suggested that similar to other mammals, rats have the areas of secondary fields of the auditory cortex which surround central coniocortex.
