Most ANNs are not similar enough to biological NNs to attempt to recreate these structures.

A feed forward network is just matrix multiplication with a nonlinearity. It could, at best, be described as biologically inspired.

Also SNNs seem to be an active field of research. Namely research center Jülich (human brain project) is conducting experiments on modeling & simulating biological neuron populations.
