The present study utilises the capacity of wheat germ agglutinin-conjugated horseradish peroxidase to label both afferent and efferent projections from selected regions of the thalamic reticular nucleus (TRN) to the pulvinar lateralis-posterior complex (Pul-LP) of the cat. Fourteen injections into the TRN located between anterior-posterior levels 8. 5 and 4. 5 were analysed. The projection of the TEN to the Pul-LP complex is roughly organised in a topographic manner and is not widespread within the thalamus.
Evidence for a nigro-pulvinar-lateralis posterior complex.
