  We study correlations between low-lying modes of the overlap Dirac operator
and vacuum defects, center vortices and three-dimensional volumes, in lattice
SU(2) gluodynamics. The low-lying modes are apparently sensitive to topological
properties of the underlying gluon field configurations while the vacuum
defects are crucial for the confinement. We find distinct positive correlation
in both cases. In case of vortices the correlation is stronger.
