The dynamical structure of the nucleon is studied in the chiral versio
n of the chromodielectric model. The color-dielectric field and the me
son clouds are described by hedgehog coherent states. Standard project
ion techniques are used to construct zero-linear-momentum eigenstates
with the nucleon quantum numbers of angular momentum and isospin. Both
the unpolarized and the polarized quark distribution functions are co
mputed. Results are in good agreement with the data and a noticeable i
mprovement with respect to the predictions of the non-chiral model is
observed.
