The cortico‐thalamic pathways from the sensorimotor cortex of the prosimian Galago crassicaudatus were studied after cortical lesions. The Glees method and several modifications of the Nauta technique were used. A short description of the thalamic nuclei in Galago is given. The motor cortex was found to project to the following nuclei: reticularis thalami, lateralis anterior, lateralis ventralis oralis, lateralis dorsalis intermedius, the pars paralamellaris of the nucleus lateralis ventralis posterior, the intralaminar nuclei, parafascicularis‐centrum medianum complex, lateral third of the mediodorsalis, praetectalis, zona incerta, H fields of Forel and the subthalamic nucleus. The cortical projections to nucleus centrum medianum was found to be topically organized. The sensory cortex was found to project to the following nuclei: reticularis thalami, lateralis dorsalis intermedius, paracentralis, parafascicularis, pars lateralis and pars medialis of the nucleus lateralis ventralis posterior, praetectalis, posterior, zona incerta, and the H fields of Forel. The topical organization of the cortical projection to the lateral complex and posterior nucleus is discussed.
