We study various dynamical properties (winding angles, areas) of a set of harmonically bound Brownian particles (monomers), one endpoint of this chain being kept fixed at the origin 0. In particular, we show that, for long times t, the areas { A_i} enclosed by the monomers scale like t^{ 1/2}, with correlated gaussian distributions. This is at variance with the winding angles { \theta_i} around fixed points that scale like t and are distributed according to independent Cauchy laws.
