By introducing the method of decomposition of almost automorphic sequence, we give some results on the almost automorphy of bounded solutions for the second-order neutral differential equations with piecewise constant argument @@@ (x(t) + px(t -1 ))'' = qx([t]) + f(t), t is an element of R, @@@ where [.] denotes the greatest integer function, p, q are nonzero constants, and f (t) is almost automorphic. Some examples illustrate our results.
