Summary Intensity and distribution of degeneration in the nucleus reticularis tegmenti pontis (N.r.t.) were mapped in silver impregnated sections following stereotactic lesions of the intracerebellar nuclei. Confirming previous results (Brodal and Szikla, 1972) fibres from the interpositus-lateralis-complex, reaching the N.r.t. by way of the crossed descending limb of the brachium conjunctivum, supply the main central part of the N.r.t. from rostral to caudal. The interpositus posterior does not appear to take part in this projection, nor do the ventralmost parts of the lateral cerebellar nucleus (NL). The caudal part of the latter appears to give off more fibres than its rostral part. Rostral and caudal parts of the interpositus anterior (NIA) appear to contribute approximately equally. Fibres from both nuclei terminate in a largely overlapping fashion in the central main regions of the N.r.t. On the whole the NIA projection is situated a little more medially than the NL projection (Fig. 8). Within both projections caudal parts of the nuclei tend to project somewhat more medially than lateral parts, especially caudally. Certain findings suggest that there may be more detailed topical relations. The organization in the cerebellar-nuclear projection onto the N.r.t. corresponds in principle to the pattern found for its other afferent contingents (especially from the cerebral cortex, Brodal and Brodal, 1971). In spite of wide overlapping there is some degree of topical order.
