Injections of the low diffusion retrograde
tracer rhodamine latex microspheres were made in the
pontine grey matter of the cat in order to study the
cortical convergence to the pons. We found a different
distribution of cells in the convex surface of the brain
hemisphere making ventral os dorsolateral injections. In
the first case, cells were grouped in the top of the gyri. In
the second case, cells were more frequent in the bottom
of the sulci. Our results show a possible retinotopic
organization of this projection
