The trigeminal nerve was unilaterally transected proximal to its ganglion in ten adult bull frogs. The course and termination of the axons were determined with the aid of Nauta and Fink‐Heimer techniques. The trigeminal primary afferents can be traced to five loci within the central nervous system, namely: the main sensory nucleus of the trigeminus, the descending nucleus of the trigeminus, a hitherto undescribed “ventral trigeminal field”, the rostral part of the nucleus of the solitary tract, and to the commissural nucleus of Cajal.
