title: Cortical projections of the thalamic mediodorsal nucleus in the rat. Definition of the prefrontal cortex.
abstract: Deposits of somatopetal tracers, that filled the entire dorsolateral cortex of one hemisphere, labelled only a few cell bodies in the thalamic mediodorsal nucleus (MD). Further experiments served to confirm the existence of strong projections from MD to the mesial and suprarhinal areas of the frontal cortex. Thus, only a very small proportion of the MD neurones in the rat projects outside the cortical areas described first by Leonard (1969). We conclude that at least in the rat, cortical projections of the MD are selective enough to be used as the basis for definition of the prefrontal cortex.
