[The direct connections of the auditory and limbic cortices in rats].

Using axonal transport of a horseradish peroxidase, studies have been made on the connections of the limbic cortex with peripheral parts of the auditory cortex in rats. Ipsi- and contralateral projections from the rostral and caudal limbic cortex to the auditory cortex were described together with peculiarities of the distribution of neurones in fields 23 and 24 of the limbic cortex which send their axons to the auditory cortex.
