The organisation of fibres within the rat basis pedunculi.
The organisation of corticofugal fibres within the basis pedunculi of rats was studied using wheat germ agglutinin-horseradish peroxidase as an orthograde tracer. Following cortical injections, labelled fibres were distributed within the cerebral peduncle in an orderly way. Fibres which originate from cells in the frontal cortex maintain a position in the ventromedial part of the basis pedunculi. Fibres from the occipital and temporal cortex travel in the most dorsolateral part. Somatosensory fibres travel between these two. The extent of labelled fibres within the peduncles is correlated with the relative density of corticopontine cells arising from different areas of the cerebral cortex.
