  We analyze the effects of noise on the traveling wave dynamics in neural
fields. The noise influences the dynamics on two scales: first, it causes
fluctuations in the wave profile, and second, it causes a random shift in the
phase of the wave. We formulate the problem in a weighted $L^2$-space, allowing
us to separate the two spatial scales. By tracking the stochastic solution with
a reference wave we obtain an expression for the stochastic phase. We derive an
expansion of the stochastic wave, describing the influence of the noise to
different orders of the noise strength. To first order of the noise strength,
the phase shift is roughly diffusive and the fluctuations are given by a
stationary Ornstein-Uhlenbeck process orthogonal to the direction of movement.
This also expresses the stability of the wave under noise.
