Before revision:  These simulations demonstrate that nonlinear interactions can impede the ability of dPCA to demix neural activity corresponding to experimental parameters , but kdPCA can still recover interpretable components  .
After revision:  These simulations demonstrate that neurally relevant nonlinearities - such as stimulus-dependent gain and rotations - impede the ability of dPCA to demix neural activity corresponding to experimental parameters , but kdPCA can still recover interpretable components .
